INTEGRATED ATT STRATEGIES FOR URBAN ARTERIALS: DRIVE II PROJECT PRIMAVERA: 2. BUS PRIORITY IN SCOOT AND SPOT USING TIRIS

This article describes a cost-effective bus priority system, using TIRIS (Texas Instruments Registration and Identification System) transponders, that was developed by the DRIVE II project PRIMAVERA. TIRIS is a radio frequency identification (RFID) system, based on low-frequency frequency modulation (FM) techniques; it is very robust to electrical noise. Its cylindrical transponder is attached to the chassis underneath a bus. TIRIS has been fully integrated with the SCOOT and SPOT urban traffic control (UTC) systems. A system was implemented at Leeds, England, to provide bus detection information, sent back from TIRIS transponders to a UTC system. The article describes the PRIMAVERA field trials which used this system. Strategies were developed at Leeds to use SCOOT or SPOT to control ten signalised intersections along the Dewsbury Road. Four of these junctions were equipped with TIRIS readers, to detect buses travelling towards the centre of Leeds. Traffic surveys were conducted under five different road network operating conditions. The morning travel times were found to be about 8% less, for buses fitted with transponders.
