BUS PRIORITY BY SELECTIVE DETECTION

This study forms part of an overall review of bus priority measures and their evaluation, currently being undertaken for TRRL. It contains a review of the state-of-the-art of selective detection in Great Britain. It examines the various potential techniques and gives details of existing installations and their performance. This is followed by a consideration of the potential impacts of bus service deregulation on bus priority measures resulting from the transport act, 1985, with particular reference to selective detection. The key area involving the choice and optimisation of control strategies is considered in detail. An analytical method of assessment was developed for this study based on original work at TRRL. Simulation techniques, although considered preferable, could not be adequately developed within the scope of this study. An overall evaluation methodology is described, with examples which is based on the researchers' recent framework for the evaluation of bus lanes. For other studies undertaken as part of the review of bus priority measures see contractor report nos 87 and 89 (IRRD 816383 and 816385 respectively).
