We know that the air is toxic, | 0:00:27 | 0:00:30 | |
so we have to try and do something. | 0:00:30 | 0:00:32 | |
I'm now looking at you as a man who is basically pumping poison gas | 0:00:32 | 0:00:36 | |
into these people's homes. | 0:00:36 | 0:00:37 | |
Research shows that your fear is unwarranted. | 0:00:41 | 0:00:44 | |
You cannot just go bang into something. | 0:00:44 | 0:00:47 | |
Don't talk on behalf of me when you're talking about businesses. | 0:00:47 | 0:00:50 | |
Have you done stuff like this before? | 0:00:50 | 0:00:52 | |
Not in this way, not in such a dynamic experiment in a city. | 0:00:52 | 0:00:55 | |
We've got some data coming in, | 0:00:59 | 0:01:01 | |
but it's hard to say exactly what's happened yet. | 0:01:01 | 0:01:03 | |
THEY COUGH AND SPLUTTER | 0:01:03 | 0:01:05 | |
Do you think it's going to work? | 0:01:15 | 0:01:16 | |
Are you optimistic? | 0:01:16 | 0:01:17 | |
# Well, he feels like an elephant | 0:01:34 | 0:01:36 | |
# Shaking his big grey trunk for the hell of it... # | 0:01:36 | 0:01:40 | |
Air pollution. | 0:01:40 | 0:01:42 | |
It's everywhere, it affects all of us | 0:01:42 | 0:01:45 | |
and you have to go to extreme lengths if you want to avoid it. | 0:01:45 | 0:01:49 | |
Right now, I'm totally protected from all the fumes from these cars | 0:01:49 | 0:01:54 | |
because this mask contains filters that are | 0:01:54 | 0:01:58 | |
designed for chemical warfare. | 0:01:58 | 0:02:00 | |
This is military-grade technology. | 0:02:00 | 0:02:03 | |
So at the moment, I'm breathing the cleanest air possible. | 0:02:03 | 0:02:06 | |
This air contains high levels of harmful pollution from industry | 0:02:08 | 0:02:13 | |
and construction, but here, mostly from vehicles. | 0:02:13 | 0:02:16 | |
To test just how dangerous the air we breathe is, | 0:02:22 | 0:02:25 | |
I'm first having to detox - free my body of pollution. | 0:02:25 | 0:02:29 | |
For the past 12 years, Dr Mark Miller has been | 0:02:31 | 0:02:34 | |
investigating exactly how traffic pollution affects us. | 0:02:34 | 0:02:37 | |
I'm his latest lab rat. | 0:02:38 | 0:02:41 | |
You should be breathing nice, clean air at the moment. | 0:02:41 | 0:02:43 | |
So we'll do all these tests, and then, after that, | 0:02:43 | 0:02:46 | |
we'll take the suit off, we'll repeat all the tests again | 0:02:46 | 0:02:49 | |
and, hopefully, we might see that air pollution actually affects | 0:02:49 | 0:02:52 | |
some of the things we've been looking at. | 0:02:52 | 0:02:54 | |
Mark will analyse my blood, | 0:02:56 | 0:02:59 | |
record my heart rate and even test how well my brain is working. | 0:02:59 | 0:03:02 | |
Having done the tests pollution-free, | 0:03:04 | 0:03:07 | |
it's time to expose myself... | 0:03:07 | 0:03:08 | |
..and get a lungful of unfiltered city air. | 0:03:11 | 0:03:14 | |
HE COUGHS | 0:03:18 | 0:03:20 | |
After three hours, I rerun the same set of tests. | 0:03:21 | 0:03:24 | |
So, can you talk me through the results? | 0:03:33 | 0:03:35 | |
So, what we did see was consistently higher blood pressure | 0:03:35 | 0:03:38 | |
once you've had your period of air pollution exposure. | 0:03:38 | 0:03:41 | |
Your blood was a little bit more likely to clot, | 0:03:41 | 0:03:44 | |
so it was, like, a little bit thicker. | 0:03:44 | 0:03:46 | |
You have a slightly higher blood pressure, | 0:03:46 | 0:03:48 | |
your arteries are a little bit more constricted, | 0:03:48 | 0:03:50 | |
a little bit more tense. | 0:03:50 | 0:03:52 | |
That's the sort of thing you would see, perhaps, if you were ageing, | 0:03:52 | 0:03:54 | |
when you get a little bit older. | 0:03:54 | 0:03:56 | |
If you were someone with heart disease, | 0:03:56 | 0:03:58 | |
that does actually increase your risk of having a heart attack. | 0:03:58 | 0:04:00 | |
I guess that, to me, is very shocking. | 0:04:00 | 0:04:02 | |
They're very small changes, but my arteries have got a bit stiffer, | 0:04:02 | 0:04:06 | |
my blood pressure has gone up and my blood has got stickier. | 0:04:06 | 0:04:09 | |
I would be very worried about those changes. | 0:04:09 | 0:04:11 | |
And what about the cognition test? | 0:04:11 | 0:04:14 | |
Is my thinking worse after the pollution than it was before? | 0:04:14 | 0:04:18 | |
There were signs that thinking was slower, | 0:04:18 | 0:04:20 | |
a little bit more dampened down. | 0:04:20 | 0:04:22 | |
Maybe not quite so sharp as you would have been | 0:04:22 | 0:04:24 | |
before you'd had the air pollution exposure. | 0:04:24 | 0:04:26 | |
Although this was a one-off, my results demonstrate the problem. | 0:04:28 | 0:04:32 | |
Given that the whole urban population is exposed long-term, | 0:04:32 | 0:04:36 | |
the consequences are terrifying. | 0:04:36 | 0:04:39 | |
In the UK alone, | 0:04:39 | 0:04:40 | |
air pollution kills 40,000 people prematurely every year. | 0:04:40 | 0:04:45 | |
It affects our brains, our blood, | 0:04:45 | 0:04:47 | |
our arteries and, of course, our lungs. | 0:04:47 | 0:04:50 | |
Scientists and MPs agree it is a public health emergency. | 0:04:50 | 0:04:55 | |
What we do about it is causing debate. | 0:04:55 | 0:04:57 | |
I'm on my way to a suburb of Birmingham called Kings Heath. | 0:05:01 | 0:05:05 | |
Like lots of built-up areas in the UK, | 0:05:05 | 0:05:07 | |
the air quality around here is pretty atrocious. | 0:05:07 | 0:05:10 | |
Lots of people have been trying to improve our air quality - | 0:05:10 | 0:05:13 | |
governments, local councils, even businesses - | 0:05:13 | 0:05:17 | |
but so far, it's a problem that isn't going away. | 0:05:17 | 0:05:19 | |
So I want to see if one community can make a difference. | 0:05:19 | 0:05:22 | |
I want to see if people power can give us the clean air we need. | 0:05:22 | 0:05:26 | |
We're here because Kings Heath is a small suburb | 0:05:29 | 0:05:32 | |
with a big traffic problem. | 0:05:32 | 0:05:34 | |
Despite a series of motorways and ring roads, | 0:05:34 | 0:05:37 | |
many drivers use Kings Heath High Street | 0:05:37 | 0:05:40 | |
as a rat run into the city centre. | 0:05:40 | 0:05:43 | |
Sat-navs have only made that worse. | 0:05:43 | 0:05:45 | |
We've tested the air here and, like many high streets, | 0:05:48 | 0:05:50 | |
it's on the cusp of the legal limit. | 0:05:50 | 0:05:53 | |
Right now, I am breathing in a cocktail of nasty substances. | 0:05:54 | 0:05:59 | |
There's loads of bad things in the air here. | 0:05:59 | 0:06:01 | |
But two of the big ones are the nitrogen oxides, | 0:06:01 | 0:06:04 | |
those are called NOx, and particulate matter, or PMs. | 0:06:04 | 0:06:08 | |
Those are coming out of the exhaust of the cars, the buses, | 0:06:08 | 0:06:11 | |
the lorries, and they're all bad for you. | 0:06:11 | 0:06:14 | |
You can't see them, you can smell them, | 0:06:14 | 0:06:17 | |
but every breath I'm taking is doing me harm. | 0:06:17 | 0:06:20 | |
This is the perfect place to try and make a change. | 0:06:21 | 0:06:23 | |
We're taking a gamble. | 0:06:25 | 0:06:27 | |
We've booked the local church hall to have a meeting about air quality. | 0:06:27 | 0:06:30 | |
But do people here care? | 0:06:30 | 0:06:32 | |
We're making a film about air pollution in the region, | 0:06:33 | 0:06:36 | |
we're trying to get people to come to a meeting at six o'clock. | 0:06:36 | 0:06:39 | |
-Do you live locally? -No, we don't. | 0:06:39 | 0:06:40 | |
You don't care? All right. Can you come at six o'clock? | 0:06:40 | 0:06:43 | |
-No, we can't. -You can't make it at six? | 0:06:43 | 0:06:45 | |
-No, we have other meetings. -We have meetings. | 0:06:45 | 0:06:48 | |
We're having a meeting about air pollution on the high street. | 0:06:48 | 0:06:51 | |
-Oh, no, thank you, I'm fine. -No? -I've got my inhaler out. | 0:06:51 | 0:06:53 | |
You've got your inhaler! Can I give you a flyer, at least? | 0:06:53 | 0:06:56 | |
Will you look at the flyer? You are really wheezing. | 0:06:56 | 0:06:58 | |
-Oh, it's not due to pollution. -Are you sure? -Yeah, yeah. | 0:06:58 | 0:07:01 | |
So, some interest in my flyers, | 0:07:02 | 0:07:05 | |
but the weather has taken a turn for the worse and I am slightly nervous | 0:07:05 | 0:07:08 | |
no-one's going to show up. | 0:07:08 | 0:07:09 | |
But, by six o'clock, the room is filling up and it looks as if | 0:07:15 | 0:07:18 | |
it might be a full house. | 0:07:18 | 0:07:20 | |
APPLAUSE | 0:07:25 | 0:07:28 | |
Hi, everybody. | 0:07:35 | 0:07:36 | |
Thank you very, very much for coming. | 0:07:36 | 0:07:39 | |
Air pollution is increasingly in the news at the moment and | 0:07:39 | 0:07:42 | |
I think it's easy to think that air pollution is either something | 0:07:42 | 0:07:45 | |
that affects people in Shanghai or people who live next to | 0:07:45 | 0:07:48 | |
a factory or a power station and not that it affects us. | 0:07:48 | 0:07:51 | |
But actually, it is a local problem here | 0:07:51 | 0:07:53 | |
and in most urban centres. | 0:07:53 | 0:07:55 | |
Children's lungs get stunted. | 0:07:55 | 0:07:58 | |
These chemicals will thicken your blood, inflame your arteries, | 0:07:58 | 0:08:02 | |
make your heart more likely to beat irregularly, | 0:08:02 | 0:08:05 | |
make you more likely to have a stroke or a heart attack, | 0:08:05 | 0:08:08 | |
make you more likely to develop asthma or, | 0:08:08 | 0:08:10 | |
if you already have asthma, have an asthma attack, | 0:08:10 | 0:08:12 | |
and they will shorten your life. | 0:08:12 | 0:08:13 | |
I'm sorry, I know we've got young people in the audience, | 0:08:13 | 0:08:16 | |
but this is the world you're living in. And the good news is, | 0:08:16 | 0:08:19 | |
there's lots of things we can do about it. | 0:08:19 | 0:08:20 | |
Yeah, I think we've become more aware of it in recent years | 0:08:20 | 0:08:24 | |
when we found out that Kings Heath High Street was the third or fourth | 0:08:24 | 0:08:28 | |
worst street for air pollution in the city. | 0:08:28 | 0:08:31 | |
That was a big shock. | 0:08:31 | 0:08:33 | |
I don't find that Kings Heath High Street is a place | 0:08:33 | 0:08:35 | |
that I want to be. | 0:08:35 | 0:08:37 | |
I avoid driving down it, walking down it. | 0:08:37 | 0:08:39 | |
I don't find it a nice place to be. | 0:08:39 | 0:08:42 | |
I think one of the problems is we don't know the scope of the problem. | 0:08:42 | 0:08:45 | |
We know general statistics, we know so many millions of people die, | 0:08:45 | 0:08:49 | |
what we don't know is exactly what's happening on the high street. | 0:08:49 | 0:08:52 | |
We can't allow more cars to block up our roads. | 0:08:52 | 0:08:56 | |
Communities don't work that well | 0:08:56 | 0:08:57 | |
when you've got streets that have busy traffic. | 0:08:57 | 0:09:00 | |
You had your hand up while that was being said. | 0:09:00 | 0:09:02 | |
We are what we are in Kings Heath. | 0:09:02 | 0:09:04 | |
It's a great place to live. | 0:09:04 | 0:09:06 | |
And if you start messing about with Kings Heath, businesses will close. | 0:09:06 | 0:09:11 | |
I'm 75, I've worked on the high street all my life, | 0:09:11 | 0:09:15 | |
fit as a fiddle. But... | 0:09:15 | 0:09:17 | |
..think carefully what they do in Kings Heath. | 0:09:18 | 0:09:22 | |
As far as I understand what you're saying, if you restrict cars, | 0:09:22 | 0:09:25 | |
businesses will lose customers, businesses will close, | 0:09:25 | 0:09:27 | |
and you can destroy a neighbourhood. | 0:09:27 | 0:09:29 | |
You can destroy a neighbourhood, yes. | 0:09:29 | 0:09:31 | |
As a business owner, I'm excited by the opportunity that | 0:09:31 | 0:09:35 | |
changes that can impact air quality and the quality of life | 0:09:35 | 0:09:38 | |
of my customers in this area, really excites me. | 0:09:38 | 0:09:41 | |
And I'm not scared of that change, scared of trying other things. | 0:09:41 | 0:09:45 | |
What I'd really like to do is build towards an experiment where, | 0:09:45 | 0:09:49 | |
on one big day, | 0:09:49 | 0:09:51 | |
we can try to make a really noticeable difference | 0:09:51 | 0:09:55 | |
in the air quality on the high street. | 0:09:55 | 0:09:57 | |
If we can do that, then we can show Birmingham, | 0:09:57 | 0:10:00 | |
we can show the whole of the UK and maybe even the whole of the world, | 0:10:00 | 0:10:04 | |
that this is possible to do. | 0:10:04 | 0:10:05 | |
That's the bit where you're all meant to stand up and cheer and cry | 0:10:06 | 0:10:10 | |
and throw your... Anyway. LAUGHTER | 0:10:10 | 0:10:12 | |
Is everyone, then, willing to join us and try to achieve | 0:10:12 | 0:10:16 | |
a day where we can drive the air pollution down | 0:10:16 | 0:10:19 | |
and prove that it is possible in a sustainable way? | 0:10:19 | 0:10:22 | |
AUDIENCE ASSENTS | 0:10:22 | 0:10:25 | |
Personally, I feel... | 0:10:25 | 0:10:27 | |
..I don't know, excited and apprehensive. | 0:10:28 | 0:10:31 | |
Does anyone else feel that way? LAUGHTER | 0:10:31 | 0:10:34 | |
OK. Thank you very, very much indeed. | 0:10:34 | 0:10:36 | |
It's gone better than I'd hoped and, within days, | 0:10:48 | 0:10:50 | |
a number of residents have come forward, keen to see | 0:10:50 | 0:10:53 | |
what can be done about their high street. | 0:10:53 | 0:10:55 | |
Sara Aboutorabi is an urban designer who lives in Kings Heath. | 0:10:56 | 0:11:00 | |
To tackle the air pollution problem, we need to change people's habits. | 0:11:01 | 0:11:05 | |
And I'm guilty of that, I hop in the car everywhere. | 0:11:05 | 0:11:09 | |
Cars are just absolutely jammed on the high street. | 0:11:09 | 0:11:11 | |
It's made me conscious to use the car less and walk more. | 0:11:11 | 0:11:15 | |
Peter Edwards is Kings Heath born and bred. | 0:11:18 | 0:11:20 | |
He works for Birmingham University. | 0:11:20 | 0:11:23 | |
We will always have naysayers who say, you can't see it, | 0:11:23 | 0:11:27 | |
or in the '60s there was smog and it was dirty and you could see it. | 0:11:27 | 0:11:31 | |
Well, I know from reading that it's scientifically proven | 0:11:31 | 0:11:34 | |
that it is there and it is killing people. | 0:11:34 | 0:11:36 | |
Stan Hems is the local butcher. | 0:11:36 | 0:11:40 | |
He's one of those who thinks pollution is far less of a problem | 0:11:40 | 0:11:43 | |
than it was in the past. | 0:11:43 | 0:11:45 | |
The pollution has got a lot better. | 0:11:45 | 0:11:47 | |
We'd have to clean this counter a four or five times a day | 0:11:47 | 0:11:51 | |
because of the fumes and the pollution of the high street. | 0:11:51 | 0:11:55 | |
Now, look, no-one has cleaned it yet. | 0:11:55 | 0:11:57 | |
My hands are clean. | 0:11:57 | 0:11:59 | |
Mohammed Farid runs the local taxi service, | 0:11:59 | 0:12:02 | |
Kate Goodall is a business manager, | 0:12:02 | 0:12:05 | |
and Cat Watton is an architect who lives and works here. | 0:12:05 | 0:12:08 | |
It is fair to say that she's not a fan of cars. | 0:12:08 | 0:12:11 | |
The high street is a very hostile place | 0:12:11 | 0:12:13 | |
both for pedestrians, for cyclists, | 0:12:13 | 0:12:16 | |
but also lots of other people. | 0:12:16 | 0:12:18 | |
So, yeah, in my own utopia, | 0:12:18 | 0:12:20 | |
I would be looking to completely block private cars. | 0:12:20 | 0:12:24 | |
And the team is meeting in a cafe | 0:12:25 | 0:12:27 | |
run by local resident James Connolly. | 0:12:27 | 0:12:29 | |
They're not short of ideas or opinions, | 0:12:29 | 0:12:32 | |
but they do agree that the high street can be improved, | 0:12:32 | 0:12:36 | |
and I found a great person to help them out. | 0:12:36 | 0:12:38 | |
-Hey, everybody. ALL: -Hello. | 0:12:38 | 0:12:41 | |
-I have brought Roland with me. -Evening, everyone. | 0:12:41 | 0:12:44 | |
Roland Leigh is a professor of air quality from | 0:12:44 | 0:12:47 | |
the University of Leicester. | 0:12:47 | 0:12:48 | |
This street, this area, is very typical of somewhere | 0:12:48 | 0:12:51 | |
where you actually have control of a lot of what is produced | 0:12:51 | 0:12:54 | |
and a lot of the impacts on health will be because of local traffic. | 0:12:54 | 0:12:58 | |
So we definitely have a situation here that's worth some action | 0:12:58 | 0:13:01 | |
and worth some management in terms of human exposure. | 0:13:01 | 0:13:04 | |
THEY LAUGH | 0:13:05 | 0:13:07 | |
What would you like to do about it? | 0:13:07 | 0:13:09 | |
Reduce the buses in the daytime, the middle of the day. | 0:13:09 | 0:13:11 | |
You've got three buses come together, | 0:13:11 | 0:13:13 | |
one is full and the other three, | 0:13:13 | 0:13:15 | |
there's two people and three people on them. | 0:13:15 | 0:13:17 | |
There are far too many buses at daytime anyway, | 0:13:17 | 0:13:20 | |
especially when the kids are coming out of school and all that. | 0:13:20 | 0:13:22 | |
There is so much traffic there. | 0:13:22 | 0:13:24 | |
Some of the residents think that parking on the busy high street | 0:13:24 | 0:13:28 | |
causes a lot of the congestion and therefore the pollution. | 0:13:28 | 0:13:31 | |
Actually, we should be making it more difficult to park, | 0:13:31 | 0:13:34 | |
-unfortunately, and I think actually having... -Why? | 0:13:34 | 0:13:36 | |
Because parking is what we want to... | 0:13:36 | 0:13:38 | |
We're talking about an issue where we've got pollution from | 0:13:38 | 0:13:40 | |
individual private cars. | 0:13:40 | 0:13:41 | |
-This is potentially an effective thing? -Yes. | 0:13:41 | 0:13:44 | |
Anything that keeps traffic flowing in general, | 0:13:44 | 0:13:47 | |
anything that doesn't stop, | 0:13:47 | 0:13:48 | |
particularly the large diesel engines. | 0:13:48 | 0:13:51 | |
The parking isn't for hours. | 0:13:51 | 0:13:52 | |
Some people are there for two minutes, three minutes. | 0:13:52 | 0:13:55 | |
They go in the Post Office, | 0:13:55 | 0:13:56 | |
buy some stamps and a card and they're back out in the car. | 0:13:56 | 0:13:59 | |
So that parking space is changed over... | 0:13:59 | 0:14:02 | |
It's stopping the traffic and therefore | 0:14:02 | 0:14:04 | |
-creating more air pollution... -No. | 0:14:04 | 0:14:07 | |
Traffic lights stop the traffic. | 0:14:07 | 0:14:09 | |
So, shouldn't pedestrians cross the road? | 0:14:09 | 0:14:11 | |
We should just let cars go free rein? | 0:14:11 | 0:14:13 | |
A lot of people have invested a lot of money in Kings Heath. | 0:14:13 | 0:14:15 | |
I'm one of them. | 0:14:15 | 0:14:16 | |
Look, I want cleaner air for myself. Honestly, I do, | 0:14:16 | 0:14:19 | |
but you have got to do everything in moderation. | 0:14:19 | 0:14:22 | |
You cannot just go bang into something. | 0:14:22 | 0:14:24 | |
I think for the day of action, removing those spaces, | 0:14:24 | 0:14:27 | |
it's one day, it's an experiment. | 0:14:27 | 0:14:28 | |
If it's a total disaster, we'll know, | 0:14:28 | 0:14:30 | |
you'll be proved right, | 0:14:30 | 0:14:31 | |
but it will be very interesting to see the net effect. | 0:14:31 | 0:14:34 | |
I actually think we've got a real great opportunity to make a bit of | 0:14:34 | 0:14:37 | |
a sea change in people's habits. | 0:14:37 | 0:14:39 | |
I guess my professional experience is that I tell people | 0:14:39 | 0:14:42 | |
all the time to do things that will be good for them, like, | 0:14:42 | 0:14:45 | |
do more exercise, lose some weight, eat your greens, stop smoking, | 0:14:45 | 0:14:48 | |
and they always ignore me completely. | 0:14:48 | 0:14:52 | |
I feel... | 0:14:52 | 0:14:54 | |
I don't want to say pessimistic, but this is terrifying to me, | 0:14:54 | 0:14:57 | |
all the things you want to do. THEY LAUGH | 0:14:57 | 0:14:59 | |
But I am totally blown away by the ambition in the room from everyone, | 0:14:59 | 0:15:03 | |
so that is very exciting. | 0:15:03 | 0:15:06 | |
The group decides on a date for their big experiment, | 0:15:09 | 0:15:12 | |
just four weeks away. | 0:15:12 | 0:15:14 | |
To see if they make any impact, | 0:15:14 | 0:15:16 | |
Roland is going to measure the pollution around Kings Heath | 0:15:16 | 0:15:19 | |
before and during the experiment. | 0:15:19 | 0:15:21 | |
I feel like almost what we've got to do is step out into the traffic | 0:15:21 | 0:15:24 | |
and just go, "No, no, sorry, you've all got to go home," | 0:15:24 | 0:15:27 | |
and that's going to be very hard to do. | 0:15:27 | 0:15:29 | |
OK, do you think they can succeed or not? | 0:15:29 | 0:15:31 | |
I would be optimistic and say, yes, they can. | 0:15:31 | 0:15:33 | |
-Really? -I am keen to see. | 0:15:33 | 0:15:35 | |
It will be a fantastic experiment to find out whether they will. | 0:15:35 | 0:15:38 | |
The power of community organising, right? | 0:15:38 | 0:15:40 | |
That's what we are going to see. | 0:15:40 | 0:15:41 | |
Have you done stuff like this before? | 0:15:41 | 0:15:44 | |
Not in this way. Not in such a dynamic experiment in a city. | 0:15:44 | 0:15:48 | |
And has this been done before? | 0:15:48 | 0:15:50 | |
Not to this extent. | 0:15:50 | 0:15:51 | |
So there have been individual traffic measures | 0:15:51 | 0:15:53 | |
where people have changed the traffic flow | 0:15:53 | 0:15:55 | |
and looked at the impact, but not when you start to think | 0:15:55 | 0:15:57 | |
about all the different ways a community can choose to act. | 0:15:57 | 0:16:00 | |
No pressure, then. | 0:16:01 | 0:16:02 | |
The trouble with pollution from most modern vehicles | 0:16:04 | 0:16:07 | |
is that it is usually invisible, | 0:16:07 | 0:16:09 | |
but you can see it if you know how to look. | 0:16:09 | 0:16:12 | |
This is a special thermal camera | 0:16:12 | 0:16:14 | |
with filters that highlight carbon dioxide. | 0:16:14 | 0:16:17 | |
Other toxic gases in the exhaust fumes behave in a similar way. | 0:16:17 | 0:16:21 | |
And the results are shocking. | 0:16:22 | 0:16:24 | |
Massive plumes from buses, cars, and, most worrying of all, | 0:16:26 | 0:16:31 | |
the diesel trucks and lorries. | 0:16:31 | 0:16:33 | |
And it's when they pull away that the worst pollution comes out. | 0:16:37 | 0:16:40 | |
Diesel engines are the monster polluters of our roads. | 0:16:43 | 0:16:46 | |
It's diesels rather than petrol engines that pump out | 0:16:46 | 0:16:49 | |
the NOx and particulate matter that damage our health. | 0:16:49 | 0:16:52 | |
From 2001 until November last year, | 0:16:53 | 0:16:56 | |
the UK Government was offering tax breaks on diesel vehicles | 0:16:56 | 0:16:59 | |
in order to combat global warming. | 0:16:59 | 0:17:01 | |
That's because they emit less carbon dioxide than petrol vehicles. | 0:17:01 | 0:17:06 | |
And it worked a treat. | 0:17:06 | 0:17:07 | |
The numbers exploded and there are now over 11 million diesel vehicles. | 0:17:07 | 0:17:13 | |
That's 40% of everything on the road. | 0:17:13 | 0:17:16 | |
Cafe owner James wants to get people out of their cars altogether, | 0:17:22 | 0:17:26 | |
but he's worried that if we talk about pollution too much, | 0:17:26 | 0:17:29 | |
it will scare people away from | 0:17:29 | 0:17:30 | |
walking and cycling in the urban air. | 0:17:30 | 0:17:32 | |
I think people feel that they are more protected in their cars | 0:17:33 | 0:17:37 | |
from pollution on the outside. | 0:17:37 | 0:17:39 | |
It doesn't feel like it gets in the car and you've got a nice, | 0:17:39 | 0:17:43 | |
safe bubble that you're sitting in. | 0:17:43 | 0:17:45 | |
And actually, when you're at the side of the road, | 0:17:45 | 0:17:47 | |
people can feel, smell, taste the pollution on the high streets. | 0:17:47 | 0:17:50 | |
I want to challenge James' ideas about cars. | 0:17:51 | 0:17:55 | |
EU regulations should already be | 0:17:55 | 0:17:57 | |
making each new generation of diesels cleaner, | 0:17:57 | 0:18:00 | |
but can the way you drive make a real difference to how much | 0:18:00 | 0:18:03 | |
pollution comes out the back end? | 0:18:03 | 0:18:05 | |
To find out, I'm getting James to | 0:18:06 | 0:18:08 | |
take me for a spin around Kings Heath. | 0:18:08 | 0:18:11 | |
So, James, in this car, | 0:18:11 | 0:18:13 | |
I have a machine that is the absolute cutting edge of | 0:18:13 | 0:18:16 | |
-emissions measurement technology. -OK. | 0:18:16 | 0:18:18 | |
Here, have a look. I mean, it is pretty cool. | 0:18:18 | 0:18:21 | |
Whoa! That looks pretty fantastic. | 0:18:21 | 0:18:23 | |
-That is amazing, right? -It is, yeah. | 0:18:23 | 0:18:25 | |
So, the really clever thing about this is that it can give you | 0:18:25 | 0:18:28 | |
the NOx output of the car in real-time. | 0:18:28 | 0:18:31 | |
I'm going to give that feedback to you while we drive around | 0:18:31 | 0:18:33 | |
and we're going to see if we can do something about it. | 0:18:33 | 0:18:35 | |
-Okey dokey. -All right? So you are behind the wheel. | 0:18:35 | 0:18:38 | |
So it is very dramatic... | 0:18:55 | 0:18:57 | |
-..the differences that I can see in your driving. -OK. | 0:18:59 | 0:19:02 | |
Don't change anything, just drive completely normally. | 0:19:02 | 0:19:04 | |
Do what you're normally doing, but I will just tell you, | 0:19:04 | 0:19:07 | |
every time you pull away, every time you accelerate, | 0:19:07 | 0:19:11 | |
you are going from NOx production ticking along at about 150 up to... | 0:19:11 | 0:19:16 | |
Well, the last time you pulled away from the lights, | 0:19:16 | 0:19:18 | |
it was more than 1,500. | 0:19:18 | 0:19:21 | |
So you've gone up ten times. | 0:19:21 | 0:19:22 | |
-And it wasn't an aggressive acceleration. -No, no. | 0:19:22 | 0:19:25 | |
It was normal. | 0:19:25 | 0:19:27 | |
You are being a completely normal driver. | 0:19:27 | 0:19:30 | |
But even that, where you were accelerating quite gently there, | 0:19:30 | 0:19:34 | |
that was up to 700. | 0:19:34 | 0:19:36 | |
Now, this road with speed bumps is interesting. | 0:19:38 | 0:19:41 | |
Basically, every speed bump is a little belch of NOx. | 0:19:45 | 0:19:51 | |
-OK. -You haven't had... | 0:19:51 | 0:19:53 | |
I mean, what's very clear from this graph is you have not had | 0:19:53 | 0:19:57 | |
a single second of steady driving | 0:19:57 | 0:19:59 | |
-where you're just cruising along at the same speed. -No. | 0:19:59 | 0:20:02 | |
-You're always accelerating or decelerating. -Yes. | 0:20:02 | 0:20:05 | |
There we go, Johnstans Butchers. | 0:20:05 | 0:20:07 | |
There you go. Big, huge spike for Stan, | 0:20:07 | 0:20:10 | |
and it wasn't you doing that deliberately. | 0:20:10 | 0:20:12 | |
No, not at all! | 0:20:12 | 0:20:13 | |
I mean, it's awful because I know it's not your fault, | 0:20:14 | 0:20:17 | |
but I'm now looking at you as a man who is basically pumping poison gas | 0:20:17 | 0:20:21 | |
into these people's homes. | 0:20:21 | 0:20:23 | |
That's not a nice person to be. | 0:20:23 | 0:20:25 | |
I don't want to be that guy. | 0:20:25 | 0:20:26 | |
-You are that guy. I can prove it here, as well. -OK. | 0:20:26 | 0:20:29 | |
So if you drive very steadily along here, just keep your speed. | 0:20:29 | 0:20:32 | |
Careful now. Just go... You're now ticking along. | 0:20:32 | 0:20:35 | |
Just gently, gently, gently. | 0:20:36 | 0:20:39 | |
You coasted all the way down here, | 0:20:39 | 0:20:41 | |
you haven't had a single spike on that bit of high street and you're | 0:20:41 | 0:20:45 | |
behind the car in front, just the way you would have been. | 0:20:45 | 0:20:48 | |
So, what we're also saying, then, | 0:20:48 | 0:20:50 | |
is it's not just about the type of vehicle you're in, | 0:20:50 | 0:20:52 | |
-it's about the driving style which is really, really important. -Yes. | 0:20:52 | 0:20:56 | |
-So that was better. -Thank you. | 0:20:56 | 0:20:58 | |
But it was really hard to try and balance that out. | 0:20:58 | 0:21:01 | |
I mean, you almost want it to give you a little electric shock | 0:21:01 | 0:21:04 | |
every time you accelerated hard. | 0:21:04 | 0:21:05 | |
I'm not sure car manufacturers would go in for that! | 0:21:05 | 0:21:08 | |
When James drove more smoothly, he dumped about 50% less NOx. | 0:21:10 | 0:21:16 | |
If everyone did this, | 0:21:16 | 0:21:17 | |
it would go a long way to solving the pollution problem, | 0:21:17 | 0:21:20 | |
but I've got something even more surprising to show him | 0:21:20 | 0:21:23 | |
and it's about where you are most exposed to fumes. | 0:21:23 | 0:21:26 | |
OK, so, look, this is the level of NOx inside the car | 0:21:26 | 0:21:33 | |
and this is the level of NOx on the street. | 0:21:33 | 0:21:37 | |
Wow, OK. | 0:21:37 | 0:21:38 | |
That's NOx, so that's the toxic stuff, | 0:21:38 | 0:21:42 | |
and you are very much more exposed to one of the more toxic pollutants | 0:21:42 | 0:21:47 | |
than I am in your car. | 0:21:47 | 0:21:49 | |
So what...? I mean, that, for me, is really surprising. | 0:21:49 | 0:21:51 | |
So James now has ammunition for persuading people | 0:21:53 | 0:21:56 | |
to get out of their cars. | 0:21:56 | 0:21:57 | |
With just a fortnight to go until the big day, | 0:22:00 | 0:22:02 | |
we need some data on the number of polluters on the high street. | 0:22:02 | 0:22:05 | |
Local resident Tom Tierney has organised a survey | 0:22:08 | 0:22:10 | |
to see what types of vehicles and how many | 0:22:10 | 0:22:13 | |
are travelling on the high street | 0:22:13 | 0:22:15 | |
in two hours on a normal weekday afternoon... | 0:22:15 | 0:22:17 | |
..and our scientists are putting up state-of-the-art pollution monitors | 0:22:20 | 0:22:23 | |
that will measure the levels of NOx and PMs | 0:22:23 | 0:22:25 | |
leading up to the big experiment. | 0:22:25 | 0:22:27 | |
Some of the more ambitious members of the group | 0:22:33 | 0:22:35 | |
want to suspend the parking bays along the high street. | 0:22:35 | 0:22:39 | |
They think the bays should go | 0:22:39 | 0:22:40 | |
because they make the traffic stop and start | 0:22:40 | 0:22:42 | |
as people try to park, dumping more pollution into the high street - | 0:22:42 | 0:22:46 | |
but Stan believes they help the businesses thrive. | 0:22:46 | 0:22:50 | |
The parking bays, if you suspend them off the high streets, | 0:22:50 | 0:22:54 | |
all that will happen is the shops will go down, | 0:22:54 | 0:22:57 | |
people won't be able to pick big parcels up. | 0:22:57 | 0:22:59 | |
If people can't park, they go to out of town and pick things up there. | 0:22:59 | 0:23:03 | |
Local architect Cat has brought me to an upmarket area | 0:23:08 | 0:23:11 | |
of Walthamstow in London. | 0:23:11 | 0:23:13 | |
She has been doing her own research | 0:23:13 | 0:23:15 | |
and is convinced that removing parking and discouraging motorists | 0:23:15 | 0:23:19 | |
is the answer for Kings Heath. | 0:23:19 | 0:23:21 | |
In 2015, the council here closed the road | 0:23:22 | 0:23:25 | |
between ten in the morning and ten at night, seven days a week, | 0:23:25 | 0:23:29 | |
and they took away all the parking bays that used to line the street. | 0:23:29 | 0:23:32 | |
This road seems a million miles from Kings Heath High Street, | 0:23:32 | 0:23:36 | |
but it does have one or two similarities - | 0:23:36 | 0:23:39 | |
like a popular local butcher. | 0:23:39 | 0:23:41 | |
-Is it Ron? -Hi! | 0:23:41 | 0:23:43 | |
-Hiya. Yeah, Ron. -Hi, how are you? | 0:23:43 | 0:23:44 | |
-Not too bad. -My name's Cat. -Nice to meet you. | 0:23:44 | 0:23:46 | |
-Hi. -Hiya. -I'm Xand. -Nice to meet you. | 0:23:46 | 0:23:49 | |
Do you know what the main reason for making the change was? | 0:23:49 | 0:23:52 | |
This was a bit of a rat run, | 0:23:52 | 0:23:54 | |
so the traffic, you were getting up to - | 0:23:54 | 0:23:57 | |
probably around about 2,000 to 3,000 cars a day | 0:23:57 | 0:23:59 | |
going through this stretch of road. | 0:23:59 | 0:24:01 | |
Plus, before the closures came in, | 0:24:01 | 0:24:02 | |
there were cars parked on this road opposite. | 0:24:02 | 0:24:05 | |
-Yeah. -So there was only one track going through, | 0:24:05 | 0:24:08 | |
-so there was congestion and the whole thing was... -Yeah, yeah. | 0:24:08 | 0:24:11 | |
So you've just got idling cars outside | 0:24:11 | 0:24:12 | |
-all the time. -Yes, all the time. | 0:24:12 | 0:24:13 | |
One of the things that I'm hearing from Stan the butcher in Kings Heath | 0:24:13 | 0:24:17 | |
is that he's worried about if no-one can park on the high street, | 0:24:17 | 0:24:21 | |
no-one is going to be able to come in and shop | 0:24:21 | 0:24:23 | |
and that business is going to suffer. Was that your experience? | 0:24:23 | 0:24:28 | |
No. It didn't affect us at all. | 0:24:28 | 0:24:30 | |
In actual fact, we got busier | 0:24:30 | 0:24:32 | |
-because a lot of people were visiting the street... -Right, yeah. | 0:24:32 | 0:24:35 | |
..and we picked up more business. | 0:24:35 | 0:24:37 | |
Overall, Ron, has it been good or bad for the area? | 0:24:37 | 0:24:40 | |
I think, personally, it's been good. | 0:24:40 | 0:24:42 | |
-That's my personal view. -And would you say there is someone else | 0:24:42 | 0:24:45 | |
in particular that we should go and speak to on this street? | 0:24:45 | 0:24:47 | |
Mark Finamore, which is two doors down. | 0:24:47 | 0:24:49 | |
-He'll probably have a different view to me. -OK, great. | 0:24:49 | 0:24:51 | |
-All right, thanks very much. -Thank you very much. | 0:24:51 | 0:24:53 | |
-Good to meet you. -Good to meet you. -Lovely. -Thanks for your time. | 0:24:53 | 0:24:56 | |
-Cheers, man. -Cheers. -Thank you. -Thank you. | 0:24:56 | 0:24:57 | |
So far, Cat's heard exactly what she wants to hear, | 0:24:59 | 0:25:02 | |
and it's hard to believe that anyone would object | 0:25:02 | 0:25:05 | |
to the improvements on this street - | 0:25:05 | 0:25:07 | |
but there are two sides to every debate. | 0:25:07 | 0:25:09 | |
The impact on me, I mean, I've been here 28 years now, I think, | 0:25:10 | 0:25:14 | |
is that it's actually quite difficult for my business. | 0:25:14 | 0:25:18 | |
I mean, my passing trade's gone, and also the issue of parking - | 0:25:18 | 0:25:23 | |
it's very limited. You know, it is fantastic here without cars. | 0:25:23 | 0:25:27 | |
I mean, you know, it is. | 0:25:27 | 0:25:29 | |
You can see that for yourself - | 0:25:29 | 0:25:31 | |
but it's just if I come down this end of the road | 0:25:31 | 0:25:33 | |
and there is nowhere for me to actually park and unload, | 0:25:33 | 0:25:36 | |
I have to then circle all the way round | 0:25:36 | 0:25:38 | |
and get to that end of the road to, hopefully, find a space there | 0:25:38 | 0:25:41 | |
to unload and bring things into my shop, | 0:25:41 | 0:25:43 | |
so I'm now creating much more pollution than I ever used to. | 0:25:43 | 0:25:47 | |
This is far from simple. | 0:25:49 | 0:25:51 | |
The street feels great, | 0:25:51 | 0:25:52 | |
but it seems as if the pollution has just been moved elsewhere - | 0:25:52 | 0:25:56 | |
and, I must admit, this looks nothing like Kings Heath to me. | 0:25:56 | 0:26:00 | |
This just feels different enough. | 0:26:00 | 0:26:02 | |
For whatever reason, it's a bit more villagey, it looks a bit different. | 0:26:02 | 0:26:05 | |
It doesn't feel quite enough on its own to win an argument | 0:26:05 | 0:26:08 | |
with Stan and the other sceptics. | 0:26:08 | 0:26:10 | |
How do you think you're going to do that? | 0:26:10 | 0:26:13 | |
I think it's very tricky, because, I think, in many ways, | 0:26:13 | 0:26:16 | |
all of us are set with our own viewpoint. | 0:26:16 | 0:26:18 | |
Even talking to Mark, | 0:26:18 | 0:26:20 | |
I still was reluctant to really see | 0:26:20 | 0:26:22 | |
that it was a bad thing in some ways. | 0:26:22 | 0:26:24 | |
It's still difficult when you really want someone to tell you | 0:26:24 | 0:26:27 | |
what you want to hear. It's very difficult. | 0:26:27 | 0:26:28 | |
The parking bays here.. | 0:26:28 | 0:26:30 | |
..are quite a big feature of what they've done. | 0:26:32 | 0:26:34 | |
-Yeah, the lack of parking bays. -Removing the parking bays... -Yeah. | 0:26:34 | 0:26:37 | |
..and that is a thing that we can trial. | 0:26:37 | 0:26:40 | |
Absolutely. | 0:26:40 | 0:26:41 | |
Back in Kings Heath, | 0:26:44 | 0:26:45 | |
Sara's meeting pollution expert Professor Rob MacKenzie | 0:26:45 | 0:26:48 | |
from the University of Birmingham. | 0:26:48 | 0:26:51 | |
He's got an idea about how to disperse | 0:26:51 | 0:26:53 | |
some of the worst of the omissions. | 0:26:53 | 0:26:55 | |
So, this is a computer simulation | 0:26:57 | 0:26:59 | |
-superimposed on a picture of the high street. -Ooh, that's fun! | 0:26:59 | 0:27:03 | |
So, the red means higher pollution. | 0:27:03 | 0:27:05 | |
-Yeah. -The green means lower pollution. | 0:27:05 | 0:27:07 | |
Is the air coming from the exhausts hot and therefore it rises? | 0:27:07 | 0:27:10 | |
The way I think about this | 0:27:10 | 0:27:12 | |
-is by analogy with blowing across the top of a milk bottle. -OK. | 0:27:12 | 0:27:15 | |
That's basically what's happening here - it's circulating inside. | 0:27:15 | 0:27:18 | |
-OK. -Because you're blowing across it, | 0:27:18 | 0:27:20 | |
you are giving the top of the air a push... | 0:27:20 | 0:27:24 | |
-Yeah. -..and that's causing all of the rest of the air to follow. -OK. | 0:27:24 | 0:27:28 | |
It's a wall of shops either side, isn't it? | 0:27:28 | 0:27:30 | |
-And that's a big problem. -Yeah. | 0:27:30 | 0:27:32 | |
What do you think we can try? | 0:27:32 | 0:27:35 | |
Well, you could look at trying to put barriers | 0:27:35 | 0:27:38 | |
-between the pedestrians and the traffic. -OK. | 0:27:38 | 0:27:42 | |
Because in the first instance, | 0:27:42 | 0:27:44 | |
what you're trying to do is just gave the air longer to mix. | 0:27:44 | 0:27:50 | |
So if you think about that hedge, there... | 0:27:50 | 0:27:51 | |
-Yeah. -..you're getting some gain | 0:27:51 | 0:27:54 | |
from pushing the air up over the hedge and down the other side, | 0:27:54 | 0:27:58 | |
because as long as the air is moving, | 0:27:58 | 0:28:01 | |
taking a long time to get from the source | 0:28:01 | 0:28:03 | |
-to the person who's breathing it... -OK. | 0:28:03 | 0:28:05 | |
..it's slowly mixing in slightly cleaner air, | 0:28:05 | 0:28:08 | |
and so it's becoming, itself, slightly cleaner. | 0:28:08 | 0:28:11 | |
You're also giving the best opportunity | 0:28:11 | 0:28:14 | |
for the pollution to be deposited onto the leaves. | 0:28:14 | 0:28:17 | |
-OK. -I mean, I guess it's a little bit of a suck and see, | 0:28:17 | 0:28:20 | |
-to be absolutely honest. -Yeah. | 0:28:20 | 0:28:22 | |
-As it gets higher... -Yeah. | 0:28:22 | 0:28:24 | |
..I'm still not promising that you'll see any effect, | 0:28:24 | 0:28:26 | |
but what I can say is, the higher it gets... | 0:28:26 | 0:28:28 | |
-Yeah. -..the more likely you'll be to see an effect. | 0:28:28 | 0:28:30 | |
Even though hedges might only make a small difference, | 0:28:30 | 0:28:33 | |
it seems worth a try. | 0:28:33 | 0:28:35 | |
Actions like adding greenery cost money, | 0:28:35 | 0:28:38 | |
and many towns and cities simply don't have budgets | 0:28:38 | 0:28:41 | |
to pay for extras like this - | 0:28:41 | 0:28:43 | |
but this could be a false economy. | 0:28:43 | 0:28:45 | |
In fact, one study has calculated that air pollution costs the UK | 0:28:45 | 0:28:49 | |
£20 billion a year in medical costs and lost labour. | 0:28:49 | 0:28:54 | |
We know that the lungs of children living in polluted areas | 0:28:55 | 0:28:58 | |
are permanently damaged, | 0:28:58 | 0:29:00 | |
so I want to try and persuade parents | 0:29:00 | 0:29:02 | |
not to drive their cars to school on our big day. | 0:29:02 | 0:29:05 | |
To do that, I need evidence that kids' lungs are being damaged. | 0:29:05 | 0:29:10 | |
So, what we want to do is look at how much pollution | 0:29:10 | 0:29:14 | |
you've all been exposed to over the course of your life, | 0:29:14 | 0:29:18 | |
and so Dr Lisa and Dr Norise, here, are experts in looking at that. | 0:29:18 | 0:29:23 | |
What they're going to do is get you to inhale, | 0:29:23 | 0:29:26 | |
basically, some salty water mist. | 0:29:26 | 0:29:28 | |
The salt is going to make everything a little bit looser, | 0:29:29 | 0:29:33 | |
so it's easier for you to cough up. | 0:29:33 | 0:29:35 | |
So it doesn't hurt, it doesn't taste funny. | 0:29:35 | 0:29:37 | |
It tastes a little bit salty. | 0:29:37 | 0:29:39 | |
Just imagine you're on a beach. | 0:29:39 | 0:29:41 | |
So, the kids have just had their nebulisers, | 0:29:42 | 0:29:44 | |
and what that's going to do is loosen up the mucus, | 0:29:44 | 0:29:47 | |
the sputum deep in their lungs | 0:29:47 | 0:29:49 | |
and then they're going to start to do some coughing | 0:29:49 | 0:29:52 | |
and bring up cells from deep in the lungs, | 0:29:52 | 0:29:55 | |
along with the mucus and sputum - | 0:29:55 | 0:29:56 | |
and in those cells, called macrophages, | 0:29:56 | 0:29:59 | |
we're going to be able to count particles of carbon | 0:29:59 | 0:30:02 | |
and the number of particles of carbon | 0:30:02 | 0:30:04 | |
will tell us how much pollution these kids have been exposed to. | 0:30:04 | 0:30:08 | |
-THEY COUGH -You guys are good! | 0:30:09 | 0:30:11 | |
Oh, that's so horrible! | 0:30:14 | 0:30:17 | |
-Xand is disgusting! -It's not very dignified, is it? | 0:30:17 | 0:30:19 | |
It's quite... What?! You... | 0:30:19 | 0:30:21 | |
I'm not doing any worse than you were doing! | 0:30:21 | 0:30:23 | |
We know that kids are most exposed | 0:30:23 | 0:30:25 | |
when they are on their way to and from school. | 0:30:25 | 0:30:28 | |
Any changes in their sputum that are down to pollution | 0:30:28 | 0:30:31 | |
are invisible to the naked eye. | 0:30:31 | 0:30:33 | |
The samples will need to be analysed in a lab | 0:30:33 | 0:30:36 | |
to discover what our exposure has been. | 0:30:36 | 0:30:38 | |
It's just ten days before the big experiment. | 0:30:42 | 0:30:45 | |
The team is meeting up to feed back on what they've been doing, | 0:30:45 | 0:30:49 | |
and Tom has got some surprising results from his traffic survey | 0:30:49 | 0:30:52 | |
about who the main culprits are. | 0:30:52 | 0:30:54 | |
Overwhelmingly, the most traffic is actually cars, private cars. | 0:30:54 | 0:31:00 | |
My impression of that was that most of them had one person, | 0:31:00 | 0:31:03 | |
that was the driver, in. | 0:31:03 | 0:31:04 | |
Sorry, I shouldn't really be interpreting, | 0:31:04 | 0:31:06 | |
-I should be just telling you. -THEY LAUGH | 0:31:06 | 0:31:09 | |
I can't help putting my own spin on it! Sorry about that. | 0:31:09 | 0:31:11 | |
The next highest number of vehicles was buses. | 0:31:11 | 0:31:16 | |
There were 64 buses. | 0:31:16 | 0:31:17 | |
That's just about 6%. | 0:31:17 | 0:31:19 | |
HGVs, there was less than I thought there would be, | 0:31:19 | 0:31:22 | |
to be absolutely honest with you. It's about 3%. | 0:31:22 | 0:31:24 | |
And what was shocking, in my view, only 16 bikes in two hours. | 0:31:24 | 0:31:29 | |
-Wow. -Mm. | 0:31:29 | 0:31:31 | |
Tom will do another survey on the big day | 0:31:31 | 0:31:33 | |
to see if we've made any difference to the number of vehicles. | 0:31:33 | 0:31:36 | |
Buses and lorries may only represent a small proportion | 0:31:38 | 0:31:41 | |
of the overall traffic, but they are major polluters. | 0:31:41 | 0:31:44 | |
National Express runs 80% of the buses in Kings Heath. | 0:31:48 | 0:31:52 | |
To make a difference, we've got to get them on board - | 0:31:52 | 0:31:54 | |
and we've managed to set up a meeting. | 0:31:54 | 0:31:56 | |
I have to say, I'm not feeling very optimistic. | 0:31:57 | 0:32:00 | |
They are a massive, multi-million-pound company | 0:32:00 | 0:32:04 | |
and I'm expecting jobsworths, gatekeepers | 0:32:04 | 0:32:07 | |
and just, sort of... they want to make money - | 0:32:07 | 0:32:10 | |
but we've got to have a go. | 0:32:10 | 0:32:11 | |
In London and Nottingham, | 0:32:16 | 0:32:17 | |
hybrid and electric buses have significantly reduced air pollution. | 0:32:17 | 0:32:22 | |
I'm wondering if Development Director Martin Hancock | 0:32:22 | 0:32:25 | |
can explain why they don't use them here. | 0:32:25 | 0:32:27 | |
Electric is very interesting. | 0:32:27 | 0:32:29 | |
At the moment, the technology doesn't really give us the range | 0:32:29 | 0:32:32 | |
we need for one of our buses. | 0:32:32 | 0:32:33 | |
Electric, I think, is about 150 miles per day without a charge. | 0:32:33 | 0:32:37 | |
Typically, our vehicles are doing 200, 250 miles a day, | 0:32:37 | 0:32:41 | |
so that's a real challenge in how we actually get electric operation | 0:32:41 | 0:32:45 | |
into the West Midlands. | 0:32:45 | 0:32:47 | |
Can you give me a sense of how many buses | 0:32:47 | 0:32:49 | |
you actually have on the high street? | 0:32:49 | 0:32:51 | |
The 50 alone is one of our most frequent services. | 0:32:51 | 0:32:54 | |
It runs every four minutes or so. | 0:32:54 | 0:32:55 | |
It carries 20,000 passengers a day. | 0:32:55 | 0:32:58 | |
Wow. | 0:32:58 | 0:32:59 | |
That's a sort of decent-sized stadium full of people | 0:32:59 | 0:33:01 | |
-you're moving up and down the high street every day. -It is. | 0:33:01 | 0:33:04 | |
Could National Express run fewer buses along the high street | 0:33:04 | 0:33:08 | |
on our day of action? | 0:33:08 | 0:33:09 | |
We really think actually maintaining the timetable | 0:33:09 | 0:33:12 | |
and keeping the same frequency | 0:33:12 | 0:33:13 | |
is the way to get more passengers onto the bus, | 0:33:13 | 0:33:16 | |
so what we could do is offer a special fare for people | 0:33:16 | 0:33:18 | |
to try the service. | 0:33:18 | 0:33:20 | |
That's a much better idea. | 0:33:21 | 0:33:22 | |
That's... Well, I guess that's why you run the bus company and I don't! | 0:33:23 | 0:33:27 | |
This is a compromise for now. | 0:33:28 | 0:33:30 | |
If fewer people drive, that could help get pollution down, | 0:33:30 | 0:33:33 | |
but, long term, cleaner buses could really help here. | 0:33:33 | 0:33:36 | |
Just a few days later, | 0:33:37 | 0:33:39 | |
James and I are up at the crack of dawn | 0:33:39 | 0:33:41 | |
to publicise the whole experiment | 0:33:41 | 0:33:43 | |
on the BBC West Midlands Breakfast Show. | 0:33:43 | 0:33:45 | |
So we've got four days to go. | 0:33:49 | 0:33:51 | |
-Yeah. -This seems like a pretty good way of reaching as many people | 0:33:51 | 0:33:55 | |
as we can. We want to shame them... | 0:33:55 | 0:33:57 | |
-No, we want to inspire them! -We want to inspire them. | 0:33:57 | 0:33:59 | |
We want to make them feel happy about getting out of their cars. | 0:33:59 | 0:34:02 | |
And empower them with information. | 0:34:02 | 0:34:04 | |
-Do you feel like people will listen? -I think they'll hear us. | 0:34:04 | 0:34:07 | |
-We've got to persuade them to listen. -Right. | 0:34:07 | 0:34:10 | |
Hi, there. | 0:34:10 | 0:34:11 | |
It quickly becomes clear that presenter Alex Lester | 0:34:13 | 0:34:16 | |
isn't going to give us an easy ride. | 0:34:16 | 0:34:18 | |
Radio for the West Midlands. | 0:34:18 | 0:34:20 | |
I'm working alongside a task force from Kings Heath in Birmingham. | 0:34:22 | 0:34:27 | |
Kings Heath High Street is very polluted. | 0:34:27 | 0:34:29 | |
It regularly exceeds what we think of as the upper limit | 0:34:29 | 0:34:32 | |
-for air pollution. -Why did you choose Kings Heath? | 0:34:32 | 0:34:35 | |
Because I know Kings Heath, and I've walked up and down Kings Heath. | 0:34:35 | 0:34:38 | |
I've been at the Hare & Hounds in Kings Heath. | 0:34:38 | 0:34:40 | |
I've had some fine times in Kings Heath. | 0:34:40 | 0:34:41 | |
-It's a lovely place. -I never felt sort of ill | 0:34:41 | 0:34:43 | |
as a result of being in Kings Heath High Street. | 0:34:43 | 0:34:45 | |
Kings Heath is a very, very typical high street. | 0:34:45 | 0:34:47 | |
You could go to any town in England, virtually, and find similar things - | 0:34:47 | 0:34:50 | |
buses, cars stuck in traffic all along the high street, | 0:34:50 | 0:34:53 | |
pouring out the pollution. What we want is people out of their cars | 0:34:53 | 0:34:55 | |
because we know that has a huge effect on air quality. | 0:34:55 | 0:34:58 | |
James, you're a business owner. | 0:34:58 | 0:34:59 | |
Are you going to stand out there on Friday going, "Ah! | 0:34:59 | 0:35:02 | |
"It's so much fresher in Kings Heath. | 0:35:02 | 0:35:03 | |
"Now, where are my customers? Customers, customers, customers... | 0:35:03 | 0:35:06 | |
"Hello, hello, hello..." | 0:35:06 | 0:35:07 | |
-No-one there. -I actually think that we'll see a difference, | 0:35:07 | 0:35:10 | |
a positive difference in the number of pedestrians | 0:35:10 | 0:35:13 | |
and there's lots of evidence out there | 0:35:13 | 0:35:15 | |
that pedestrians spend more money on the high street - | 0:35:15 | 0:35:18 | |
and, actually, in stationary traffic or slow-moving traffic, | 0:35:18 | 0:35:22 | |
pollution is worse when you're inside your car, | 0:35:22 | 0:35:24 | |
so get out of your vehicle, | 0:35:24 | 0:35:26 | |
get the bus, cycle, walk and, actually, | 0:35:26 | 0:35:28 | |
it should be better for the businesses there. | 0:35:28 | 0:35:30 | |
How do you think that went? | 0:35:32 | 0:35:34 | |
-It goes fast, doesn't it? -Yeah. | 0:35:34 | 0:35:35 | |
-I think we got most of the points across. -I think so. | 0:35:35 | 0:35:38 | |
I didn't want him putting anyone off Kings Heath High Street. | 0:35:38 | 0:35:41 | |
I feel like that's not... | 0:35:41 | 0:35:43 | |
We want people to come, but not use their cars, so I'm hoping... | 0:35:43 | 0:35:47 | |
We didn't mention the buses. | 0:35:47 | 0:35:50 | |
-We didn't. -That's OK. | 0:35:50 | 0:35:52 | |
You can deal with that. You can do some flyers. | 0:35:52 | 0:35:54 | |
I'll do that, thanks. | 0:35:54 | 0:35:55 | |
The radio show has given us a big audience across Birmingham, | 0:36:02 | 0:36:06 | |
but there's one group of people I want to engage with personally - | 0:36:06 | 0:36:10 | |
the children of St Dunstan's School on Drayton Road. | 0:36:10 | 0:36:13 | |
Our scientists have put up monitors right outside the school gates | 0:36:13 | 0:36:17 | |
to measure these kids' exposure to exhaust fumes. | 0:36:17 | 0:36:19 | |
Just so you get an idea of the geography, | 0:36:20 | 0:36:22 | |
the high street is right down there at the end of the road, | 0:36:22 | 0:36:25 | |
and just before you get to it is James' Gorilla Cafe, | 0:36:25 | 0:36:28 | |
and at school-run time in the morning and the afternoon | 0:36:28 | 0:36:31 | |
this road is completely jam-packed, | 0:36:31 | 0:36:33 | |
and it's a huge source of traffic problems. | 0:36:33 | 0:36:36 | |
So what I'm hoping is that I can get the kids here | 0:36:36 | 0:36:38 | |
to use their pester power | 0:36:38 | 0:36:40 | |
to get their parents involved in our Clean Air Day. | 0:36:40 | 0:36:42 | |
So, everybody, can you put your hands together and welcome Dr Xand? | 0:36:46 | 0:36:50 | |
So, one of the things that we wanted to know about | 0:36:53 | 0:36:55 | |
is what you think of air pollution. | 0:36:55 | 0:36:57 | |
Do you know what part of the body this is? | 0:36:57 | 0:36:59 | |
Lungs? | 0:36:59 | 0:37:00 | |
You think it's lungs. | 0:37:00 | 0:37:01 | |
You are exactly right. | 0:37:01 | 0:37:03 | |
We did this experiment. | 0:37:03 | 0:37:04 | |
It was quite disgusting, really. | 0:37:04 | 0:37:06 | |
We basically had to do a lot of coughing and splitting into cups. | 0:37:06 | 0:37:09 | |
We got cells out of them | 0:37:09 | 0:37:10 | |
and we looked at the cells under the microscope | 0:37:10 | 0:37:12 | |
and what you can see, there are black dots in all of these cells. | 0:37:12 | 0:37:17 | |
This is one of the kids'. That huge black dot, there, | 0:37:17 | 0:37:20 | |
that's a piece of soot from a diesel engine. | 0:37:20 | 0:37:23 | |
So what we really want to do | 0:37:23 | 0:37:25 | |
is change the pollution on Kings Heath High Street. | 0:37:25 | 0:37:28 | |
Who thinks that's a good idea? | 0:37:28 | 0:37:30 | |
-ALL: -Me! | 0:37:30 | 0:37:33 | |
Now, who came to school by car this morning? | 0:37:33 | 0:37:36 | |
Yeah, lots of people, right? | 0:37:37 | 0:37:38 | |
And we know some of you have to come to school by car, | 0:37:38 | 0:37:42 | |
but there might be a few of you who could walk, | 0:37:42 | 0:37:45 | |
who might be able to take a scooter | 0:37:45 | 0:37:47 | |
and see if, on Friday, you could come a different way to school | 0:37:47 | 0:37:50 | |
and make a bit less pollution. | 0:37:50 | 0:37:52 | |
We want you to go home, talk to your to your mum, your dad, | 0:37:52 | 0:37:54 | |
your guardians, whoever looks after you, | 0:37:54 | 0:37:56 | |
and try and get them to help make a difference. | 0:37:56 | 0:37:59 | |
Do you think you can do it? | 0:37:59 | 0:38:00 | |
-ALL: -Yes! | 0:38:00 | 0:38:02 | |
Who's up for giving it a go? | 0:38:02 | 0:38:04 | |
-Me! -Come on! Who's up...? It doesn't sound very enthusiastic! | 0:38:04 | 0:38:07 | |
-Who's up for giving it a go? -ME! | 0:38:07 | 0:38:10 | |
Well, that was very encouraging. The kids listened, | 0:38:11 | 0:38:14 | |
or at least they looked like they were listening, | 0:38:14 | 0:38:16 | |
but we only have a few days left till Friday, | 0:38:16 | 0:38:19 | |
till the Clean Air Day, and things like this have to work | 0:38:19 | 0:38:22 | |
if we're going to make a difference to the air pollution around here. | 0:38:22 | 0:38:24 | |
So I'm just hoping those kids will get home | 0:38:24 | 0:38:27 | |
and hassle their parents into making some changes. | 0:38:27 | 0:38:30 | |
Cutting down cars on the school run could have a big impact | 0:38:34 | 0:38:38 | |
on our experiment. | 0:38:38 | 0:38:40 | |
Back on the high street though, it's stop-start driving we have to tackle | 0:38:40 | 0:38:44 | |
and the traffic lights don't seem to be helping. | 0:38:44 | 0:38:46 | |
At the moment, these traffic lights work on timed cycles. | 0:38:46 | 0:38:51 | |
If the lights were synchronised and the parking bays were suspended, | 0:38:51 | 0:38:55 | |
the traffic might run more smoothly, | 0:38:55 | 0:38:57 | |
then I think we stand a fighting chance. | 0:38:57 | 0:39:00 | |
To do any of that, we're going right to the top - to the council. | 0:39:01 | 0:39:05 | |
We're meeting Councillor Lisa Trickett, | 0:39:08 | 0:39:10 | |
who's in charge of making Birmingham a greener city. | 0:39:10 | 0:39:14 | |
We've got a shopping list of demands. | 0:39:14 | 0:39:16 | |
It's notoriously bureaucratic to change anything that affects traffic | 0:39:16 | 0:39:20 | |
and we're working to a tight deadline, | 0:39:20 | 0:39:22 | |
but Lisa has a reputation to live up to. | 0:39:22 | 0:39:25 | |
If it's temporary, we aren't so bound by levels of consultation | 0:39:26 | 0:39:30 | |
and we can argue that we're trialling this, so it is possible. | 0:39:30 | 0:39:36 | |
And surely you're also a bureaucratic ninja, aren't you? | 0:39:36 | 0:39:39 | |
I mean, can't you get your way through all this? | 0:39:39 | 0:39:43 | |
I have the battle scars, yeah. | 0:39:43 | 0:39:45 | |
We didn't get any promises, did we? | 0:39:46 | 0:39:48 | |
-No. -No. -She is a councillor, after all. -We'll make it happen. | 0:39:48 | 0:39:51 | |
I do actually have some faith, I do have some faith. | 0:39:51 | 0:39:55 | |
It's the day before the big experiment | 0:39:55 | 0:39:57 | |
and the bus company has come good. | 0:39:57 | 0:39:59 | |
They've given us 200 free tickets. | 0:39:59 | 0:40:02 | |
We want people to use buses tomorrow instead of driving, | 0:40:02 | 0:40:05 | |
so Kate is dishing them out on the high street. | 0:40:05 | 0:40:08 | |
We're doing a day of action for clean air | 0:40:08 | 0:40:11 | |
and I'd like to give you one of these and a badge. | 0:40:11 | 0:40:13 | |
-Oh, thank you very much. -Thank you very much. All right. | 0:40:13 | 0:40:16 | |
-Thank you very much. -Have a nice day. -Thank you, and you. | 0:40:16 | 0:40:18 | |
-Come tomorrow and use the bus. -Ah, good on you. | 0:40:18 | 0:40:20 | |
-Yeah. -Thank you very much. | 0:40:20 | 0:40:21 | |
-Would you like a free bus ticket to come by bus tomorrow? -No. | 0:40:21 | 0:40:24 | |
No? OK, thank you. | 0:40:24 | 0:40:25 | |
-OK, thank you very much. -Yeah. -Thank you. -Bye. -Bye! | 0:40:25 | 0:40:28 | |
We haven't yet heard back about synchronising the traffic lights, | 0:40:32 | 0:40:36 | |
but, in the nick of time, we discover that the council | 0:40:36 | 0:40:38 | |
has delivered on the parking bays. | 0:40:38 | 0:40:40 | |
As night falls, the suspension notices go up, | 0:40:40 | 0:40:44 | |
though not everyone is happy. | 0:40:44 | 0:40:46 | |
How do people feel about tomorrow? Stan? | 0:40:46 | 0:40:48 | |
Ideally, if it was purpose-built in what we're doing, fantastic. | 0:40:48 | 0:40:52 | |
I'm all for it. | 0:40:52 | 0:40:53 | |
But as it is now... | 0:40:53 | 0:40:55 | |
..I think, you know, you've got to consult the shopkeepers | 0:40:56 | 0:40:59 | |
that are paying a lot of rents and a lot of rates before you do anything. | 0:40:59 | 0:41:04 | |
For me, what I'm really excited about is | 0:41:04 | 0:41:06 | |
that it starts to build a data bank, an information bank, | 0:41:06 | 0:41:10 | |
for us to start to actually think, is there a better way, | 0:41:10 | 0:41:14 | |
is there something that we can do for our kids | 0:41:14 | 0:41:16 | |
and for our grandkids that is better? Or... | 0:41:16 | 0:41:19 | |
..this is as good as it gets? | 0:41:19 | 0:41:21 | |
We need to do things like this in order to understand | 0:41:21 | 0:41:26 | |
-how we can make improvements. -Yeah. | 0:41:26 | 0:41:28 | |
This evening, some of us, not all of us, | 0:41:28 | 0:41:30 | |
are going to be going out and actually filling those parking bays | 0:41:30 | 0:41:35 | |
with greenery. | 0:41:35 | 0:41:37 | |
The team has managed to get hold of 60 feet of hedging, | 0:41:44 | 0:41:48 | |
Portuguese laurel to be precise, | 0:41:48 | 0:41:50 | |
and to try and make as big an impact on the pollution as possible, | 0:41:50 | 0:41:54 | |
the bushes are nearly six-foot high. | 0:41:54 | 0:41:56 | |
Moving this much shrubbery takes a lot of muscle. | 0:41:56 | 0:41:59 | |
Oh, there we go! | 0:42:01 | 0:42:03 | |
-Ah, it's Xander! -Hey, everybody. | 0:42:06 | 0:42:08 | |
-What are you doing here? -Can I help? -Thank you for joining us! | 0:42:08 | 0:42:11 | |
-Thank you for joining us. -No, I insist. | 0:42:11 | 0:42:13 | |
-Come on, I'll help you. Right, on three. -This could be heavy. | 0:42:13 | 0:42:15 | |
-One, two, three? -One, two, three. | 0:42:15 | 0:42:17 | |
-Heavy! -We've done the whole parking bays all the way down. | 0:42:21 | 0:42:23 | |
Oh! This is real work, eh? | 0:42:23 | 0:42:25 | |
You've got it from here, Cat. I think... | 0:42:25 | 0:42:27 | |
-Man, that's the last one. -Sara, you've got it. | 0:42:27 | 0:42:30 | |
-Well done. Well done. -Is that it? -Yes. | 0:42:30 | 0:42:33 | |
-Well, I'm glad I could help. -That was amazing. | 0:42:33 | 0:42:36 | |
Glad I could be of assistance. | 0:42:36 | 0:42:38 | |
-Right, then. -Has anyone asked about what you're up to? | 0:42:38 | 0:42:40 | |
-Yes. -Yeah, loads of people. -Yeah? -We've had a mixed reception. | 0:42:40 | 0:42:43 | |
We've also had cars honking at us going, "Yeah!" | 0:42:43 | 0:42:46 | |
-CAR HONKS Really? -There you go! -Hooray! | 0:42:46 | 0:42:49 | |
-Honk if you want more hedges. -Yeah. -Honk for hedges. | 0:42:49 | 0:42:53 | |
-Honk for hedges! -Well, I'm very impressed. -There's our slogan! | 0:42:53 | 0:42:56 | |
I'm very impressed, I have to say. | 0:42:56 | 0:42:58 | |
I think we're also a bit mad, to be honest. | 0:42:58 | 0:43:00 | |
-The cold has driven us all mad. -You do, you are looking all a bit manic, | 0:43:00 | 0:43:02 | |
I have to say. You're looking slightly crazed. | 0:43:02 | 0:43:05 | |
The hedge gang, late at night. | 0:43:05 | 0:43:08 | |
How do you think it's going to go tomorrow? | 0:43:08 | 0:43:09 | |
Do you think it's going to work? | 0:43:09 | 0:43:11 | |
Even if it's one unit of improvement, | 0:43:12 | 0:43:15 | |
I am positive that you will see it. | 0:43:15 | 0:43:18 | |
Possibly. | 0:43:19 | 0:43:20 | |
I think it's going to be really difficult to measure it in one day. | 0:43:20 | 0:43:23 | |
These guys have worked wonders. | 0:43:26 | 0:43:28 | |
They've got all these hedges in, | 0:43:28 | 0:43:29 | |
they've got the parking bays suspended, | 0:43:29 | 0:43:31 | |
they've launched Clean Air Day. | 0:43:31 | 0:43:33 | |
A little help from me, I got a bit of free bus travel, | 0:43:33 | 0:43:36 | |
so that should help. We do have a few other cards up our sleeves, | 0:43:36 | 0:43:39 | |
but I have to say, with a high street like this... | 0:43:39 | 0:43:43 | |
..I don't know if it's going to be enough. | 0:43:44 | 0:43:46 | |
Finally, after weeks of planning and preparation, the big day is here | 0:43:55 | 0:44:00 | |
and it's another early morning date with local radio for me. | 0:44:00 | 0:44:03 | |
-Good morning. -Good morning. | 0:44:03 | 0:44:05 | |
This is my last chance to persuade car drivers, | 0:44:05 | 0:44:08 | |
especially parents about to start the school run, | 0:44:08 | 0:44:11 | |
to try something different today. | 0:44:11 | 0:44:13 | |
The trouble is, it's bitterly cold | 0:44:13 | 0:44:15 | |
and I'm worried that today, of all days, | 0:44:15 | 0:44:17 | |
people will prefer their cars to walking. | 0:44:17 | 0:44:20 | |
Some of the pupils from St Dunstan's School | 0:44:23 | 0:44:26 | |
have already made a clever alteration | 0:44:26 | 0:44:28 | |
to the way they get to class. | 0:44:28 | 0:44:30 | |
This is the St Dunstan's walking bus. | 0:44:30 | 0:44:32 | |
Are you doing all right? | 0:44:34 | 0:44:36 | |
Good. This is making me feel very happy, this walk to school. | 0:44:36 | 0:44:40 | |
It's a good way to start the day. | 0:44:40 | 0:44:42 | |
How far do you have to come in the car before you get dropped off? | 0:44:45 | 0:44:47 | |
Right, well, you've all done brilliantly. | 0:44:54 | 0:44:56 | |
Are you excited about Clean Air Day? | 0:44:56 | 0:44:58 | |
-ALL: -Yes! | 0:44:58 | 0:45:00 | |
The pavement looks busier to me, | 0:45:02 | 0:45:04 | |
but deputy head Mark McLoughlin is better placed to judge it. | 0:45:04 | 0:45:07 | |
I'm on the gate, front of house, morning and afternoon. | 0:45:07 | 0:45:10 | |
And does it look any different today? | 0:45:10 | 0:45:12 | |
Oh, yeah, as I said, | 0:45:12 | 0:45:13 | |
there's a sizeable reduction in the amount of cars, the queueing... | 0:45:13 | 0:45:18 | |
Normally speaking, at this point where we're standing right now, | 0:45:18 | 0:45:20 | |
there might be a queue of cars to the street 150 metres to our left. | 0:45:20 | 0:45:24 | |
This road and the high street have both been rigged with sensors | 0:45:25 | 0:45:28 | |
to measure pollution. | 0:45:28 | 0:45:30 | |
In the pub down the road, the sensors are being monitored | 0:45:30 | 0:45:33 | |
by Professor Roland Leigh from the University of Leicester | 0:45:33 | 0:45:36 | |
and Dr Francis Pope from the University of Birmingham. | 0:45:36 | 0:45:39 | |
It's these two who are going to have to tell us by the end of the day | 0:45:39 | 0:45:43 | |
whether or not our people-power emissions-busting has worked. | 0:45:43 | 0:45:47 | |
It weighs a tonne! | 0:45:54 | 0:45:56 | |
At the top of the high street, | 0:45:56 | 0:45:57 | |
James is busy trying to promote our big day | 0:45:57 | 0:46:00 | |
by putting up an oversized banner. | 0:46:00 | 0:46:02 | |
It looks like the wind is proving something of an obstacle. | 0:46:06 | 0:46:09 | |
While James ties himself up in knots, | 0:46:10 | 0:46:12 | |
Councillor Lisa Trickett has popped down to Kings Heath | 0:46:12 | 0:46:15 | |
and she's got a surprise for me. | 0:46:15 | 0:46:17 | |
She's actually managed to get the traffic light sequencing changed, | 0:46:17 | 0:46:21 | |
although she's not the expert on how it works. | 0:46:21 | 0:46:24 | |
I'm not the person to talk to. | 0:46:24 | 0:46:26 | |
I suggest we go and get Kevin in his bunker | 0:46:26 | 0:46:28 | |
-and have a conversation with him. -Who's Kevin in the bunker? | 0:46:28 | 0:46:30 | |
He is sort of in charge of traffic and highways. | 0:46:30 | 0:46:33 | |
Hi, can I speak to Kevin? | 0:46:33 | 0:46:35 | |
-PHONE: -Yeah, who's speaking, please? -Lisa. Councillor Lisa Trickett. | 0:46:35 | 0:46:39 | |
Hold on. | 0:46:39 | 0:46:40 | |
Has the penny dropped? | 0:46:43 | 0:46:44 | |
PHONE RINGS | 0:46:46 | 0:46:48 | |
-Hello? -Hi, is that Kevin? -It is, yes. | 0:46:48 | 0:46:51 | |
Xand wanted to know a few things | 0:46:51 | 0:46:53 | |
that were a bit too technical for my liking. | 0:46:53 | 0:46:56 | |
Kevin, are you, with regard to traffic lights on Kings Heath, | 0:46:56 | 0:47:00 | |
you're kind of God, is that right? | 0:47:00 | 0:47:02 | |
KEVIN CHUCKLES | 0:47:02 | 0:47:04 | |
What we have got is this control centre. | 0:47:04 | 0:47:06 | |
We've got sight through the CCTV cameras | 0:47:06 | 0:47:08 | |
of what's happening to the traffic. | 0:47:08 | 0:47:10 | |
Birmingham's Traffic Control Centre is about to try an experiment here | 0:47:10 | 0:47:14 | |
for the first time - synching up the lights | 0:47:14 | 0:47:17 | |
to keep traffic flowing smoothly. | 0:47:17 | 0:47:19 | |
They call it the green wave. | 0:47:19 | 0:47:22 | |
If you hit a green light, you can move at a continuous speed | 0:47:23 | 0:47:27 | |
along the high street and, therefore, | 0:47:27 | 0:47:29 | |
not put out too much pollution, is that the idea? | 0:47:29 | 0:47:31 | |
The principle of green waves is exactly that, yep. | 0:47:31 | 0:47:34 | |
That's really good. Well, that is amazing. | 0:47:34 | 0:47:36 | |
-The gods, the gods of traffic. -The gods, yeah. | 0:47:36 | 0:47:39 | |
-Amazing. -Such power! | 0:47:39 | 0:47:40 | |
Can you literally, like, change the traffic lights behind us? | 0:47:40 | 0:47:44 | |
Yeah, we can change the traffic signals to green right now | 0:47:44 | 0:47:47 | |
with a click of my fingers to Gary. | 0:47:47 | 0:47:50 | |
It's gone green! There you go. | 0:47:55 | 0:47:56 | |
If someone pushes the button, | 0:47:57 | 0:48:00 | |
a pedestrian pushes the button to cross, | 0:48:00 | 0:48:02 | |
-does that mess up the phasing? -No, it won't. | 0:48:02 | 0:48:04 | |
There will, obviously, be time for pedestrians and cyclists to cross, | 0:48:04 | 0:48:07 | |
but that will be fixed in with the green wave timings. | 0:48:07 | 0:48:12 | |
Kevin, that's brilliant. Thank you very much indeed. | 0:48:12 | 0:48:14 | |
The only problem with making the traffic flow better | 0:48:16 | 0:48:19 | |
is that drivers using sat navs might be re-routed this way | 0:48:19 | 0:48:23 | |
because the road is clearer. | 0:48:23 | 0:48:25 | |
But I wonder if I can harness sat nav technology myself. | 0:48:25 | 0:48:29 | |
One of the things I'm going to try and do to prevent people | 0:48:29 | 0:48:31 | |
driving their cars along the high street, | 0:48:31 | 0:48:33 | |
which is a little bit naughty, but I guess I don't feel too bad about it, | 0:48:33 | 0:48:37 | |
is I'm using one of the traffic apps, one of the navigation apps, | 0:48:37 | 0:48:40 | |
to flag up that the traffic is worse than it actually is. | 0:48:40 | 0:48:44 | |
I'm going to say that it's a standstill. | 0:48:44 | 0:48:46 | |
I'm going to add a comment that this is a nightmare day for traffic here | 0:48:46 | 0:48:50 | |
and then other users will see that and, hopefully, | 0:48:50 | 0:48:53 | |
the app will route them somewhere else. | 0:48:53 | 0:48:56 | |
Of course, this could lead to congestion elsewhere | 0:48:56 | 0:48:59 | |
as people try to get around my blockage. | 0:48:59 | 0:49:01 | |
I don't think I should do it every day, | 0:49:02 | 0:49:04 | |
but I'm hoping, today, that will... | 0:49:04 | 0:49:05 | |
that will make the point that less traffic will reduce the pollution. | 0:49:05 | 0:49:09 | |
Fingers crossed. | 0:49:09 | 0:49:11 | |
Despite everything we've put in place, | 0:49:12 | 0:49:14 | |
the traffic does still appear to be backed up in places, | 0:49:14 | 0:49:18 | |
so are we actually making a difference? | 0:49:18 | 0:49:21 | |
So, this pub is the nerve centre of our monitoring operation | 0:49:21 | 0:49:26 | |
and, in here, the two profs, Roland and Francis, | 0:49:26 | 0:49:28 | |
are crunching the numbers, | 0:49:28 | 0:49:30 | |
so I'm going to find out how we're getting along. | 0:49:30 | 0:49:32 | |
Is it working? | 0:49:32 | 0:49:34 | |
-How are you doing? -Hey! Very well. -Very nice to see you. | 0:49:34 | 0:49:37 | |
-Are you doing all right? -Yeah. -So, how is it going? | 0:49:37 | 0:49:40 | |
A bit early to tell. We've got some data coming in, but, yeah, | 0:49:40 | 0:49:43 | |
hard to say exactly what's happened yet. | 0:49:43 | 0:49:45 | |
We haven't got the data from today ourselves yet. | 0:49:45 | 0:49:47 | |
We've got yesterday's data up until this morning. | 0:49:47 | 0:49:50 | |
-OK. -So... -You're not giving anything away. -No. -Not yet, no. -OK. | 0:49:50 | 0:49:53 | |
All right, all right, all right, keep me in suspense. | 0:49:53 | 0:49:56 | |
While I've got them here, I want some more details | 0:49:56 | 0:49:58 | |
on how we can protect ourselves from pollution. | 0:49:58 | 0:50:02 | |
I mean, we've seen some data that says that it can be worse | 0:50:02 | 0:50:06 | |
inside a car than on the street. | 0:50:06 | 0:50:08 | |
Is there anything you can do about that? | 0:50:09 | 0:50:11 | |
Can you put a filter on your car or anything? | 0:50:11 | 0:50:13 | |
Is there a trick to that? | 0:50:13 | 0:50:15 | |
A car will filter its air to an extent | 0:50:15 | 0:50:17 | |
and that works rather better for particulate matter | 0:50:17 | 0:50:19 | |
than it does for NOx, particularly the larger particles, | 0:50:19 | 0:50:22 | |
so if you do just turn to internal circulation when you think | 0:50:22 | 0:50:26 | |
it might be polluted outside, | 0:50:26 | 0:50:27 | |
you will help to an extent with the larger particles. | 0:50:27 | 0:50:30 | |
-Really? That little button that no-one ever presses? -Mm-hm. | 0:50:30 | 0:50:33 | |
The circle arrow? | 0:50:33 | 0:50:34 | |
If you're sat behind a bus and you can see the plume, | 0:50:34 | 0:50:37 | |
if you just switch to internal circulation, | 0:50:37 | 0:50:39 | |
you will at least avoid pulling in that immediate pollution. | 0:50:39 | 0:50:42 | |
Francis and Roland are comparing all their Kings Heath data | 0:50:44 | 0:50:48 | |
to the general level of pollution in the Birmingham area, | 0:50:48 | 0:50:51 | |
so the experiment will only have worked if Kings Heath has gone down | 0:50:51 | 0:50:55 | |
compared to the rest of the city. | 0:50:55 | 0:50:58 | |
With no results in yet, | 0:50:58 | 0:51:00 | |
I want to know if the traffic has reduced on the high street. | 0:51:00 | 0:51:03 | |
Tom has an army of volunteers out counting cars, | 0:51:04 | 0:51:06 | |
including Charlotte and her son Tom. | 0:51:06 | 0:51:09 | |
-How are you doing? -All right, thank you. | 0:51:09 | 0:51:11 | |
-You seem quite busy. -It's a busy high street! | 0:51:11 | 0:51:13 | |
-Yeah. -Car. | 0:51:13 | 0:51:15 | |
They're very concentrated on doing this traffic survey | 0:51:15 | 0:51:18 | |
and counting the cars as they come by. | 0:51:18 | 0:51:20 | |
Have you got all the ones that have just come? | 0:51:20 | 0:51:22 | |
-Yep. -How's it going? -Good. -Yeah? -Yeah, we've got a lot of cars. | 0:51:22 | 0:51:25 | |
How many...? You haven't added them up so far. | 0:51:25 | 0:51:27 | |
-You're doing the check marks. -Yeah. | 0:51:27 | 0:51:29 | |
-10, 15... -Car. -OK. Ah! Sorry, sorry, sorry. | 0:51:29 | 0:51:31 | |
Car, HGV. | 0:51:31 | 0:51:33 | |
-This is quite nerve-racking, actually. -Yeah. | 0:51:33 | 0:51:35 | |
-Is it stressful keeping an eye on it all? -Yeah. | 0:51:35 | 0:51:38 | |
Car, car, van. | 0:51:38 | 0:51:39 | |
-Van. -Yes. -Van. | 0:51:39 | 0:51:42 | |
Car. | 0:51:42 | 0:51:43 | |
Bus. | 0:51:43 | 0:51:44 | |
Worryingly, when they tot up the numbers, | 0:51:49 | 0:51:52 | |
the total volume of traffic hasn't gone down at all. | 0:51:52 | 0:51:55 | |
Despite that, over in Drayton Road, James is having a street party. | 0:51:55 | 0:51:59 | |
He knows that more pedestrians means more footfall, | 0:51:59 | 0:52:03 | |
so he's trying to pull in customers | 0:52:03 | 0:52:04 | |
who might normally have been in cars. | 0:52:04 | 0:52:07 | |
But have the celebrations been premature? | 0:52:08 | 0:52:11 | |
As the afternoon rush hour dies away, it's time to find out. | 0:52:11 | 0:52:15 | |
What you have been trying to do is something really extraordinary | 0:52:17 | 0:52:21 | |
and you are a community of people who've come together | 0:52:21 | 0:52:24 | |
around this issue, so I am absolutely blown away. | 0:52:24 | 0:52:26 | |
My heart is pounding and I am genuinely quite nervous, | 0:52:26 | 0:52:30 | |
so we cannot wait any longer for this information. | 0:52:30 | 0:52:33 | |
Roland, your monitors were on the high street. | 0:52:33 | 0:52:35 | |
-Can you talk us through it? -OK, so, the high street is challenging. | 0:52:35 | 0:52:39 | |
You've got buses, you've got HGVs. | 0:52:39 | 0:52:41 | |
A lot of places are just exceeding by one or two micrograms. | 0:52:41 | 0:52:45 | |
It might be 42, 43, so even a 5% change | 0:52:45 | 0:52:48 | |
could bring a lot of places into legal compliance. | 0:52:48 | 0:52:52 | |
What you have in your high street today is a reduction of NO2... | 0:52:52 | 0:52:56 | |
-..of 10% from everything you've done... -Wow! Really? | 0:52:58 | 0:53:01 | |
-..which is absolutely huge. -APPLAUSE | 0:53:01 | 0:53:03 | |
Well done, everyone. Phenomenal. | 0:53:03 | 0:53:06 | |
That is amazing! | 0:53:06 | 0:53:08 | |
We thought the traffic was flowing a bit more smoothly today | 0:53:09 | 0:53:12 | |
than it was previously. | 0:53:12 | 0:53:14 | |
How much difference do you think that might make? | 0:53:14 | 0:53:16 | |
In my opinion, that's the biggest factor. | 0:53:16 | 0:53:18 | |
That's the biggest change down the high street today, is keeping | 0:53:18 | 0:53:21 | |
the vehicles moving, reducing the stop-start as much as you can. | 0:53:21 | 0:53:25 | |
It really reduces the amount of fuel burnt | 0:53:25 | 0:53:27 | |
and the amount of emissions produced. | 0:53:27 | 0:53:29 | |
Our parking bay suspensions, hedges, bus vouchers | 0:53:29 | 0:53:32 | |
and traffic light changes seem to have paid off. | 0:53:32 | 0:53:35 | |
Around St Dunstan's School, though, we had just one plan - | 0:53:35 | 0:53:38 | |
get people out of their cars. | 0:53:38 | 0:53:41 | |
So did that single strategy work? | 0:53:41 | 0:53:43 | |
You did a great job around the school today. | 0:53:43 | 0:53:47 | |
A lot of parents and a lot of people changed their behaviour | 0:53:47 | 0:53:49 | |
quite significantly. | 0:53:49 | 0:53:51 | |
That's a road where you had a lot of control over what went on. | 0:53:51 | 0:53:54 | |
Can we have the numbers? | 0:53:54 | 0:53:56 | |
For NO2, you managed to change the concentrations... | 0:53:56 | 0:54:01 | |
-..by 20%. There was a 20% reduction... -Wow! | 0:54:01 | 0:54:03 | |
-That's amazing! -..in NO2 around the school. Well done. | 0:54:03 | 0:54:06 | |
That is amazing! | 0:54:08 | 0:54:10 | |
-So, so, NOx is a big deal for children's health. -Yeah. | 0:54:10 | 0:54:14 | |
In terms of particles getting into their brains, lung development, | 0:54:14 | 0:54:17 | |
it's the particulate matter that really counts. | 0:54:17 | 0:54:19 | |
-Yeah, I think that's true. -OK. | 0:54:19 | 0:54:21 | |
So, we went through the numbers, we crunched the numbers | 0:54:21 | 0:54:24 | |
and I can say... | 0:54:24 | 0:54:25 | |
..that you've managed to reduce it by 30% during drop-off and pick-up. | 0:54:27 | 0:54:31 | |
Wow. That is really good! | 0:54:31 | 0:54:33 | |
-That's massive, right? -Yeah. That's huge. | 0:54:36 | 0:54:40 | |
And that's a real school with real children | 0:54:40 | 0:54:43 | |
breathing in real pollution. That is amazing. | 0:54:43 | 0:54:47 | |
I mean, this is your road, James. | 0:54:47 | 0:54:49 | |
-It's OUR road. -Yeah. -It's our community's road. | 0:54:49 | 0:54:51 | |
So I'm really excited that the community action has managed | 0:54:51 | 0:54:54 | |
to make an impact on their wellbeing. Really good. | 0:54:54 | 0:54:57 | |
If you're trying to persuade a parent to leave their car at home, | 0:54:57 | 0:55:00 | |
I mean, that's a stick to beat people with, isn't it? | 0:55:00 | 0:55:03 | |
You know, if you're cutting down particulate matter by 30%... | 0:55:03 | 0:55:07 | |
I mean, you see these numbers all the time. | 0:55:07 | 0:55:09 | |
-30% reduction... -Yeah, absolutely. | 0:55:09 | 0:55:11 | |
I mean, there's no safe limit so anything you can reduce, | 0:55:11 | 0:55:13 | |
1% would really help. 30% is massive. | 0:55:13 | 0:55:16 | |
I think the important thing to encourage change | 0:55:16 | 0:55:18 | |
is to have that data cos that makes people want to keep it up, | 0:55:18 | 0:55:21 | |
not just for a special day. | 0:55:21 | 0:55:23 | |
That's... I'm feeling, like, whoa! | 0:55:23 | 0:55:26 | |
Whoa! OK, OK, good stuff. | 0:55:26 | 0:55:28 | |
Can I just say that I have... | 0:55:28 | 0:55:30 | |
..been quietly pessimistic? | 0:55:31 | 0:55:34 | |
And I was pretty much 100% certain | 0:55:34 | 0:55:38 | |
that you would've made no real difference at all. | 0:55:38 | 0:55:41 | |
There are so many people that were pro | 0:55:41 | 0:55:44 | |
and so excited that we were getting up and we were doing something. | 0:55:44 | 0:55:48 | |
We had so many new customers come in today. | 0:55:48 | 0:55:52 | |
So many people that, even though they lived in Kings Heath, | 0:55:52 | 0:55:55 | |
had not heard about us before and out of curiosity they came down. | 0:55:55 | 0:55:59 | |
I've already had two businesses where you put the hedge in | 0:55:59 | 0:56:02 | |
phone me and say, "What's happening? We pay a lot of rent here | 0:56:02 | 0:56:07 | |
"and our customers can't get in to pick things up." | 0:56:07 | 0:56:09 | |
-Oh, no, really? -Really. Two businesses. | 0:56:09 | 0:56:11 | |
-I thought you were going to say they phoned and were really happy. -No. | 0:56:11 | 0:56:14 | |
Did you get any phone calls from anyone who was happy? | 0:56:14 | 0:56:17 | |
-No. -Really? -Honest. | 0:56:17 | 0:56:19 | |
I've only seem to get the groans. | 0:56:19 | 0:56:21 | |
I almost have a sort of lump in my throat. | 0:56:23 | 0:56:25 | |
I really think you have done an extraordinary thing | 0:56:25 | 0:56:27 | |
for the health of your community that maybe will take a while | 0:56:27 | 0:56:30 | |
to sink in and I think it is extraordinary what you've done. | 0:56:30 | 0:56:33 | |
This was just one day in one place, | 0:56:34 | 0:56:37 | |
but what this experiment has shown is that when local people, | 0:56:37 | 0:56:41 | |
the council and businesses come together | 0:56:41 | 0:56:44 | |
it IS possible to make Britain's polluted air cleaner. | 0:56:44 | 0:56:48 | |
I feel absolutely flipping great! | 0:56:48 | 0:56:52 | |
I think the results are absolutely staggering, actually, | 0:56:52 | 0:56:55 | |
especially the school results. | 0:56:55 | 0:56:57 | |
We're going to be benefiting from this, but other people are as well. | 0:56:57 | 0:57:00 | |
So, yeah, definitely worth it. Definitely worth all the cold feet! | 0:57:00 | 0:57:03 | |
We've talked about this sort of thing a lot, | 0:57:03 | 0:57:05 | |
but we've never actually followed through and done it | 0:57:05 | 0:57:08 | |
and it happened today and that's what I really like. | 0:57:08 | 0:57:10 | |
Thank you for showing us the power of communities. | 0:57:10 | 0:57:12 | |
What you're doing is good for people's health, | 0:57:12 | 0:57:15 | |
but I still think we've still got to look after the businesses | 0:57:15 | 0:57:19 | |
in Kings Heath. | 0:57:19 | 0:57:20 | |
I think that what we've been able to start to do is arm people | 0:57:20 | 0:57:24 | |
with information about an unseen danger and I'm really, | 0:57:24 | 0:57:28 | |
really proud of Kings Heath and proud of the people | 0:57:28 | 0:57:30 | |
and proud of what they've done. | 0:57:30 | 0:57:33 | |
