So. You have your experience, I have mine. The changes I'm talking about are not confined to the congestion charge zone. Regardless of what may have happened there, traffic light timings were and are being altered throughout London, including in places where the congestion charge can have no possible relevance. > You are trying, presumably deliberately to confound history, policy and > physics.

You are trying, presumably deliberately, to imply that every increase in the all-red phase is politically motivated, to slow motor traffic, and none is for other reasons, such as safety. You may not have noticed that we are in agreement that excessive all-red time is a bad thing. > I'm guessing that you're one of the newbies who had no experience of > what a mess Hanger Lane was until a decent traffic engineer from Plessey > sat on a stool by the side of the road and worked out how those > responsible at the GLC had fouled up the signal phasing. Traffic light timings tend to be set according to traffic models and then adjusted in the light of experience. I am glad to hear the second stage happened at Hanger Lane. As it happens I use the Gyratory most days, and the northbound queues seem as bad as, or worse than, ever. Maybe other directions do better, but it's still a mess at busy times. That's because no amount of fiddling with signal timings can help if there's just too much traffic. >> I am involved in Transport Planning now. > > In what capacity, where?

If the free-for-all leads to speeds that are so slow that any collision would be trivial and many collisions would be avoided altogether, then I don't see how the throughput of the junction would be better than if 50% of the time traffic could travel at 30 mph and 50% of the time it was stationary. Anyway, it could be 100% safe but it still would be hellishly stressfull if you never knew whether you had priority over anyone else and had to be prepared to stop every few yards because someone might pull out in front of you. It's stressful walking along a street when people walk in front of me all the time and I have to keep stopping or avoiding them; why should we extend this to vehicles on the road as well?

So that everyone is operating on the same basis. You would cease to worry about other people breaking the rules (which causes them to obstruct your path) because there would be no rules.

Just because others do something, it doesn't excuse those who should know better. Putting on the lights on your bike when its dark is pretty basic!

Sure, and for the same reason I always carry double the legally required complement of lights on my bikes and routinely spend more on the lights for a given bike than most people do on the bike itself. The debate over the use of tail lights on agricultural trailers in the early 20th Century went along similar lines.
