The problem is not just the traffic being forced onto main roads. As those main roads become (have become) more congested than previously, they become less viable routes so alternative routes are taken by drivers in order to address the persistent delays on main roads. This means that other (previously quieter) roads become more congested, with drivers rushing to make-up time and experiencing frustration (associated behaviours) as these smaller roads are clogged with cars coming both ways in their quest to achieve something like a reasonable journey time. While I agree we all want a cleaner and safer environment, I do wonder where this displacement is acknowledged in the portrayal of 'success' of these schemes. I am not convinced the measuring of these consequentially affected outlying roads was conducted before, or after, the schemes were implemented and therefore feel that declaration of success, failure, or any other outcome cannot be taken seriously. Increased traffic volumes, speeding increases and pressure points, on school / nursery roads no less, is not a win. This is not withstanding other unmeasured / incorrectly sampled aspects of these schemes. The mother of Ella has said she's against LTNs because they drive traffic onto main roads such as the South Circular which was the cause of her daughter's death. Dulwich Common (and Lordship Lane at the junction of it) have seen increased traffic since the Dulwich Village LTN was introduced as cars which used to filter down Court Lane now get stuck in queues reaching to/from the Village. And forcing yet more traffic down main roads (which I remind you some of our local councillors have suggested is the rightful place for displaced traffic) is going to mean there are many more children suffering from the effects of increased pollution who happen to live on them - this is a point often overlooked/ignored by the pro-LTN lobby - we can't use some roads, and the people who live on them, as collateral damage in the fight for a reduction in pollution - how on earth is that fair?
