Abstract

An increasing range of bus priority systems is being implemented in London to help bus operational efficiency and encourage greater use of the bus relative to private transport. An important and growing application in London concerns the provision of priority using traffic signzlling, including "selective detection" techniques, to provide active priority for buses. These techniques in which signals respond to individual buses detected on signal approaches, are implemented at many isolated junctions and systems have also been triaUed successfully in SCOOT UTC regions (Bretherton et al, 1996). There remain significant areas controlled by fixed time UTC in London and, with London's 6,000 buses now largely fitted with transponders, there is a need to extend priority into these areas.

This paper describes the development and characteristics of a new system for bus priority in fixed lime UTC in London called SPRINT, and its implementation and preliminary evaluation on a section of the Uxbridge Road in West London.
