This is just spin to justify the continued and extended use of red light cameras. They have come up with a genuine way to improve safety at traffic lights, but they don't want to lose the opportunity to keep the revenue flowing in as a result.....
I agreee that there is much in the proposal which makes sense, in theory at least. However I've just thought of three other problems.
1. The idea that if there is "no traffic" approaching a light turning red, the other one can go green sooner, could pose serious safety problems for cyclists. If I ride up to a red light across conventional under-road sensors, often the sensors don't "see" me. I habitually wiggle the bike from side to side to increase the chance that I will be detected. This
usually works. However under the new system, the light could turn amber just as I was passing the stop line, the system would not have "seen" me, and cars would start off on the cross road before I had had a chance to complete the crossing.
2. The idea that "the system can tell drivers that if they stick to a certain speed below the limit, they will find a succession of lights changing in their favour” sounds good in theory, but I doubt if it will work in practice. Take the A34 Kingsway in Burnage, South Manchester. The limit is 40, but most people realised that if they did just under 50, they would go through every light on green. The spacing of cross roads made this possible in both directions at this speed, and the phasing was adjusted to suit rush hour traffic. And just under 50 was a perfectly safe speed for that road. So Manchester Council decided to erect flashing signs saying "40 - slow down". Now enough people do exactly 40 that there is little if any chance of going through every light on green. So we all have to stop half way along.
3. The idea of controlling vehicle speed remotely keeps coming up, and is positively Orwellian. There have been cases where a car has started to pull out of a side road just as I was approaching it, and a quick burst of speed has got me past safely. If the system had immediately applied the brakes, I would probably have suffered a side on collision.
There are many improvements that can be made to traffic lights. However they must be carefully thought out first, and this proposal obviously hasn't been. One thing which could be done immediately would be to remove the red/amber phase. Very few countries still use this phase - not even the Irish Republic, I was surprised to find - and it serves no useful purpose. [I'm not sure if Switzerland and Germany still use it, but I can't think of any other European countries that ever did.] It was - I believe - originally introduced to allow drivers sufficient time to force the car into gear, so that they would be ready to proceed when the light went green. It should go the way of the licensing laws. Archaic, outdated nonsense.
