ITS system of slower speed limits on roads leading into congested areas will only work if every warning sign is fitted with a speed camera - we all know how much notice is paid to speed limits if there are no cameras around!!

Britexpat - I believe they claim less pollution as although the journey may still take the same time, the car can be travelling at a more economical speed (slower) and does not stop and wait in traffic cues. This also helps hot spots of pollution in congested areas. The main idea is that traffic flow is better and that journey time actually does become less as junctions themselves become more efficient. The Corniche is one area where the green traffic lights do connect on each junction, which keeps the traffic moving.....unless too much traffic is there - again this is what ITS should help regulate
