Selective vehicle detection

Selective vehicle detection is a system used by London Buses in order to allow traffic signals to selectively favour buses' movement through intersection by changing traffic light sequences and timings as buses approach. The current system works using 'bus detectors' mounted on lampposts and similar posts by the side of the road, which detect transmission made by transmitters aboard buses. Transport for London are working on a new system which would instead use GPS to track the location of buses.
