Chiswick roundabout was always vulnerable but does seem to have got worse. As some of the utility works around Kew bridge have gone its not clear why congestion is so bad. North circular in particular I hear has been terrible for a while. There are various roadworks across Acton and the water main repair near Shepherds bush. But with the news that leakages at Thames water have actually got worse and it will miss targets,  expect even more roadworks.This all explains my scepticism when a certain regular poster claims that the closure of Hammersmith bridge has reduced congestion and traffic on major roads in the area. It defies logic and is in conflict with all other data. On the Putney SW15 site the MP is calling for Hammersmith bridge to reopen as she highlights the appalling air quality in Putney.Wandsworth bridge is set to close for 10 weeks in mid July which will make things even worse in Putney and have knock on effects further west. As we saw with when there were emergency utility works near Kew Bridge, river crossings are already at capacity and more closures/roadworks are a fact of life, which in turn drive more congestion. We need to reopen one of the few bridges we have.There are too many cars, especially those driven into London each day. More efforts need to be done to address this, but it seems that LTNs and cycle lanes alone are not doing much. The strategy of creating congestion to reduce car use is painful for many and its not clear it works.

"There are too many cars, especially those driven into London each day. "No argument from me about this Bill.There are a range of possible measures to address this, including road pricing.Some of the proposals for road pricing rely on technology, so basically a GPS/communications device in the vehicle that reports where/when the vehicle has been driven and a charge is based upon this.  The conspiracy theorists will have a field day about that.Other proposals are low tech, such as the vehicle mileage is annually reported in a MOT and the driver is charged based upon that.  Someone doing 10 miles a day in the Scottish Highlands does not have the same impact of someone doing the same distance in London so I don't know if that would be allowed for.Another mechanism is parking - no point driving if there is nowhere to park or very expensive to park.Hounslow did propose a workplace parking levy for businesses along the A4 west of Chiswick roundabout and the funds for this were targeted at a new rail station providing a shuttle service to link with the Elizabeth line at Southall.  Businesses hated it, of course.  I don't know the status of the proposal.Within Chiswick, if you look at the section of Wellesley Rd by the A4 bridge, there are always cars parked there during the week.  The CPZ there isn't 24 hours so I assume drivers with more flexible work hours drive in, park their cars there and maybe use the tube at Gunnersbury or visit Chiswick Business Park.You could do your own little bit to discourage people from driving into London by lobbying Cllr Biddolph to change the hours of operation of the CPZ at this location to be 24 hours.

Tom, my point is a reasonable one which I am sure you realise but choose to be obtuse. I understand what the data shows. I also understand that there have been improvements in London air since 2016 and some areas have further benefited from both the first phase of the ULEZ and in the case of Putney specificlly a move to lower emmissions bus fleets. So a quite legitimate quesiton is how air quality improvements in Putney compare to other areas.The second point as you again realise is indeed that the INRIX scorecard is for all of London. And it shows clearly increased congestion in 2022, despite the very measures you reference in terms of 'restrictions on traffic and support for active travel' which were made across London. Which begs the question whether we really believe your limited analysis thats shows some miraculous fall around certain roads in west London whilst the rest of the city saw an increase. The closure of Hammersmith bridge shows no evidence that restrictions are effective. Its just a road that crosses a river. The data on which you rely is also incomplete, such as for key roads such as the A4. You obsess about it as if its some magical thing. If you really believe this rubbish, you should be calling for the immediate closure of all bridges in all urban areas. By your logic all traffic congestion will disappear.To translate your final point, when you reference the 'standard relationship between supply and demand'. So to be clear, what you want is more road closures and then more congestion in the hope that this reduces traffic. Some of us would rather take a more proactive approach that doesnt shift traffic and congestion. THe INRIX scorecard shows your approach is failing.

Paul, I'm really not down any anti-science rabbit hole and your attempt to insult and label anyone who disagrees is pathetic. The trouble is you and others reject anyone who doesnt share your particular focus on one mode of travel.Tom makes certain assertions and I am challenging them. He may be right, its hard to tell at present, not least as the datasets he used have gaps. Again, there are some legitimate questions:1) Has air quality improved in Putney more or less than other similar areas not impacted by the bridge closure? 2) is there something unique about bridges that makes traffic disappear. Or perhaps is it the flawed starting assumption that all journeys that crossed one bridge MUST then either cross another bridge or not happen? Tom claims that a large area of west London and key roads have not seen any increase in congestion whereas we know London as a whole clearly has. I agree that this effect may be lost in broader London data, so what the borough level analysis show? This might be expected to show up if the effect is real or not if its just that travel patterns adjust.I would love to see less traffic and congestion in London, but afraid not convinced your solutions provide it, certainly not on their own. At least be honest and acknowledge that you are calling for more congestion, at least in the short term. Such a strategy, if there is a mandate to implement, might even benefit from proper coordination and a parallel boost to public transport.

Bill George ● 1184d

I dont think there are easy solutions, but a number would help. First and foremost, and no doubt unpopular for some, is an expanded congestion charge to reduce the daily flood of traffic into London every day. The one Tom claims the problem is all local traffic, but if you stand by the A4 you might have a different view.Second would be cheaper and better public transport with more accessible stations, we saw under Ken Livingstone this can work. We currently seem to be pricing people off public transport. Thirdly a coherent and well researched coordinated plan to decide whether we should have further measures such as LTNs in more areas. In terms of CPZs, its crazy that LBE and LBH have made some parking available for commuter traffic, so yes we should stop it. We should also tax all workplace parking with all funds to go to public transport. A coherent strategy would also look at improving parking at stations around London to discourage car use. I can equally ask regarding Tom why he chooses to argue with everything I post? This is a discussion forum. I see him making assumptions that I believe reflect his own bias and not real world experience. Lets not forget he was telling this forum that there were no problems whatsover with the first 'temporary' CS9 installation and the loss of the left turn filter onto Chiswick Lane, right up to the point that TFL announced they were digging it up to reinstall the left hand filter and other measures including some lost bus lane.We also have a lack off consistent full year data for 2022 and its equally hard to unpick the COVID effect from historic data.

Paul, it is cheaper to drive than get the train.  That's the main reason people drive.  If I want to get the train to my home town in Devon today, the cheapest ticket the the Trainline is £55.  If I want to book a ticket on Monday 3rd July at 8 in the morning, it's £148.  Those are for single fares.  If I drive sensibly, I could do it on around £22 of petrol.  With numbers like that, it's no wonder people drive. Every other major European country regards railways as part of the national infrastructure and subsidises them.  It doesn't make sense that we subsidise cars by spending billions upon billions on roads, but expect railways to fund themselves out of tickets.  It's also made worse by private rail operators taking profits out of the system.You aren't going to get people out of their cars without making the railways competitive on price.The other problem is that public transport is often slow because it doesn't go directly where you need it to go.  That journey to my home town is slower by public transport.  Allowing for possible delays on the Tube, and a ten minute walk to the station at this end, I'd need to be leaving home a good hour before the train is due to leave Paddington.  The station is 6 miles from my home town at the other end, and buses are not frequent in Devon.  It would be a good 20 minute walk from the bus station in the centre of town to my parents' old house.  It's going to take significantly longer by public transport.  That's before you start thinking about the costs, which I mentioned above.Many journeys in outer London are also a lot slower by public transport.  If my wife were to get public transport to work, it's 3 buses.  It's much quicker to drive.In London, bikes solve the speed issue, if you use the right route.  The last 4 offices I've worked in have been significantly quicker to get to by bike than by public transport (or car).  Adding 5 minutes plus to the journey by using your cycle lane wouldn't help though.  I wouldn't be going that way if I still worked in central London.Bikes are quicker, as are cars in much of the country, because they go door to door.  Public transport is never going to go door to door for most people, so it's always going to be slow.  Outside of London, and other major cities, that's going to make it difficult to get people out of cars.  In London though, we can solve a lot of the problems by getting a lot more people cycling.  I agree with you on that.One thing we should do to encourage cycling is adopt the Canadian standard on electric bikes.  In Canada, they are allowed to provide assistance to the rider up to 20mph instead of the 15mph we have here.  Outside of London, that could get a lot of people out of their cars.  If I use my hometown as an example again, it's 15 miles to Exeter.  There are some people who cycle that route, but most people aren't going to cycle that distance under their own power.  It's going to take an hour on a currently legal electric bike.  Even with rush hour traffic, it's around 45 minutes in a car.  A 20 mph electric bike would be the same time as a car, and a lot cheaper to run.  That would get people switching.It's perfectly possible to get a normal bike up to 20mph on the flat, and well beyond that downhill.  When I've tracked rides using GPS on my phone, I've got up to 35mph.  I used to go down some of the hills in Devon a lot faster than that when I was young.Limiting electric bikes to 15mph just seems stupid when you can go a lot faster on an ordinary bike.  The other thing that slow electric bikes do is encourage illegal ones.  I see large numbers of illegal electric bikes.  If legal ones could do a sensible speed, then people wouldn't need to buy illegal ones, or monkey with the governors on legal ones.  20mph bikes that meet standards are going to be safer than dodgy illegal bikes.The added advantage of 20mph electric bikes in London is that they could keep up with the traffic, with all the 20mph speed limits we have now.  That would make it a lot less intimidating for cyclists.We also need to look at wider issues.  Why is commuting 50 miles plus accepted as a normal thing?  There need to be jobs where people live.  That should mean a moratorium on new office buildings in cities like London.  Build residential in London, so that people can afford to live nearer their work.  On the other side of that, build offices in the towns 20 to 50 miles from London, so that there will be jobs near home for the people who live there.  These ridiculously long commutes need to become a thing of the past.

When Professor Carlos Moreno first postulated the concept of 15 minute cities he focused on bringing daily necessities closer to residents not on restricting traffic movement although transport reduction would naturally flow from their introduction. The mistake that ‘blinkered visionaries’ have made is to implement the traffic restrictions in the belief that the 15 minute city would flow from this. It will not.I would love to see the return of ‘popping down the shops’ to pick up everything I need but the return to those days has gone, even Professor Moreno calls his concept a utopian ideal.Successive governments, both local and national and of all ‘hues’ have trashed local high streets with restrictive policies and allow the virtually uncontrolled development of out of town ‘shopping theme parks’. The resultant desert left means that many local shops and services, essential to delivering the 15 minute city have gone forever, never to return.Locally in Boston Manor and within a fifteen minute 'radius' we have, over the last thirty years, lost three doctors surgeries, two dentists, two cinemas and no fewer than nineteen corner shops (all but one of which have been converted to housing). No local butcher, greengrocer, hardware shop, hairdresser or chippie within 15 minutes of home and no concept of them returning.Edward Glaeser (Chairman of the Harvard department of Economics) wrote “Aspects of the 15-minute city are praiseworthy. I yield to no one in my embrace of the pedestrian city. I have long believed that walking as the best of all possible modes…..but the basic concept of a 15-minute city is not really a city at all. It’s an enclave — a ghetto – a subdivision. All cities should be archipelagos of neighbourhoods, but these neighbourhoods must be connected. Cities should be machines for connecting humans – rich and poor, black and white, young and old. Otherwise, they fail in their most basic mission”.Professor Glaeser wrote in a blog post for the LSE that “We should embrace the good aspects of the 15-minute city— the idea of accessibility, perhaps driving less, and embracing congestion pricing — ultimately, we should bury the idea of a city that is chopped up into 15-minute bits”.Those who seek to restrict traffic flow in isolation as delivering an enforced 15 minute city would do well to reflect on the wise words of Professors Moreno and Glaser.

I’m a driver. I really like cars. And I support higher taxation in general  to support funding of local services, health and amenities and sustainable energy and transport initiatives. Specifically I also support  massive increases in fuel duty, CPZ permit costs, clean air zone charges, congestion zone charges and road pricing to recognise the true costs of externalities of private car use and use those funds to subsidise more sustainable transport alternatives including trains and trams. Plus free cycle hangars for example. Obstinate polluters should pay heavily for their choices and the damage they cause. I also support planting cherry trees and local initiatives that attract people to Chiswick to support local businesses. I also spend a lot of money in Chiswick at local businesses. You on the other hand contribute absolutely nothing to our area. Your posts are entirely fixated on your increasingly vain efforts to protect the supremacy of the car in a Borough in which you do not live and where you contribute nothing whatsoever to local services. You sit in Ealing on your computer lobbing insults at people who are active in improving Hounslow. The only fixated obsessive here is you Nigel with your determination to oversimplify  and demonise anybody who dares suggest we need to restrict and reduce private car use for the benefit of our area. Goodness know why you have this compulsion to do it because nobody is listening to you and you have no impact. Why don’t you get a more productive and healthy hobby?
