Lua error in package.lua at line 80: module 'strict' not found. Selective vehicle detection is, or was, the name of a bus priority 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.

As of 2007, the system worked using 'bus detectors' mounted on lampposts and similar posts by the side of the road, which detect transmission made by transmitters aboard buses, developed as part of Transport for London's Countdown bus tracking system.[1] TfL was, at that time, considering whether to use newer, GPS-based, bus location systems to supplant the existing beacon-based infrastructure.[1]

As of 2011, a new bus location system, Countdown II, was in the process of being commissioned.[2]
