In Bristol I would like to use speed detection equipment to cut the green = for speeding vehicles rather than extend it as is normal in sde etc = equipment.=20 This would involve detecting speeds and dropping the green signal in = favour of a red signal. My proposaL is to leave the rest of the junction = as if the green was still present and to provide a red light camera to = catch the offending drivers. We would probably need detection equipment located a couple of hundred = metres out but that is not a real problem in these days of radio coms and = fibe networks, we had even thought of using closely linked signals and = passing the information between them. There would of course need to be a lot of safeguards and I would propose = using a 30 mph limit to start with but I believe we have to stop people = from driving fast at signals in the knowledge that they will get more time = to clear the junction if we want to improve road safety. =20 Any comments on this ?
