| Jeremy, I was showing the 2016 map as an example. A model done now would clearly use more recent traffic survey data, of which there is lots. Traffic patterns now haven't changed that much putting aside what happened during the pandemic. The most polluted part of the area is clearly beside the A4 and from DfT traffic counts (site 46121 near Hogarth roundabout), 2019 average daily traffic was over 100k while in 2021 it was 85k. Changes of plus or minus a couple of thousand vehicles on other roads won't mean a significant difference to air quality. Just a thousand vehicles per day may be too many for some roads, but the issue here is one of safety and disruption of quality to life to residents on the road. A thousand vehicles per day won't produce enough pollution to get close to health limits - you need the 10s of thousands of vehicles per day on road like the A4 for that. You are ignoring the other disbenefits of too much traffic along residential streets. You still have no solution about what happens to the almost 100k vehicles per day on the A4. Claiming it should be dispersed to other roads is nonsense. As for "if a road has reached the limit of the amount of traffic it is carrying, then that traffic does need to be dispersed", that is just reflecting the dinosaur "predict and provide" policies of the 60s and 70s as typified by the ring way project mentioned on another thread. If the road is congested, then tough shit for the drivers - they should choose another time or another mode of transport, they don't get to rat-run through residential streets. Given £17B has been spent on Elizabeth line running parallel to the A4/M4, nothing should be done to increase capacity on the road network. |
