VEHICLE DETECTION IN NORWICH

This article describes the testing of Selective Vehicle Detection (SVD) and a Passenger Transport Information System (PTIS) on the Airport Park and Ride service, a key element of the Norwich Transportation Strategy of Norwich, England. Consultants were asked to assess all possible options of both SVD and PTIS; initial findings suggested that SVD could be made compatible with a SCOOT area traffic control system. The proposed scheme was to use SVD to give priority to the Park and Ride buses at six signal-controlled junctions. After consideration of the three available types of SVD equipment, the Siemens Traffic Controls Ltd loop and transponder system was chosen as the most suitable. Here, transponders under the vehicles to be detected communicate with inductive loops cut into the road surfaces. At each signalled junction, a 'local logic unit' emits a radio signal to a nearby loop. Priority can be given to a vehicle by: (1) stage advance; (2) stage interrupt; or (3) stage extension. Three more loops, at the city centre, transmit information from transponders to a central computer, which performs several information and control functions. The SVD and PTIS systems should be installed by Autumn 1995; the scheme's success is predicted.
