In reply to timjones:
Let's step back a moment.
A small (some would say it's large) minority of cyclists run red lights.
The question is (or should be) why?
One reason might be that they are high risk takers, adrenaline addicts if you like, that get a thrill out of it. I think this is unlikely for the majority.
The most likely reason is that there isn't enough time for a cyclist to safely get through the lights and junction from a standing start. This obviously depends both on the cyclist and the particular junction but for the purposes of this argument we'll assume a typical UK style crossroads with lights rather than the US style dual carriageway crossroads.
So how do we reduce cyclists jumping red lights? Preferably stop though I don't think you could get it to zero in the same way that you are unlikely to reduce speeding by motorists to zero. Some options:
1. Police crackdown, prosecuting all cyclists who jump red lights.
2. Change the law to allow cyclists to "roll through on red" - the Idaho roll mentioned in the article.
3. Change the light sequence in some manner that gives cyclists a few seconds grace to get across the junction before motorised vehicles get the go-ahead.
#1 solves the symptom but not the cause. It needs at least one policeman on every junction all the time. Not really viable.
#2 semi-legalises red light jumping. Personally I'm not too keen on the "turn left on red" idea either, this would encourage the creeping up on the inside of large vehicles that leads to so many of the cyclist deaths.
#3 Is perhaps the "least worst option" when all road users are considered. It's reasonably easy to implement as it is mainly a software change in the lighting controller. Perhaps the main danger is drivers taking the new sequence as go rather than waiting.
