Interaction of buses and signals at road crossings - deliverable 1 - review of bus priority at traffic signals around the world - final report

The review presented in this report has confirmed that bus priority at traffic signals is being adopted increasingly around the world with applications ranging from small towns to big cities. The deployment of bus priority systems has been found to be very dependent on (i) the existing infrastructure, particularly the traffic signal control system, (ii) the characteristics of the bus operations and (iii) the policy and Institutional context in which both operate. As a result, a wide variation in priority architectures, technologies used and strategies deployed have been found, with insufficient impartial evidence to compare the cost-effectiveness of alternative approaches. The main focus of this work was on bus priority at traffic signals. This report contains sections as follows: Introduction; Bus priority methods; Traffic signal control systems and strategies; Bus priority at traffic signals; Examples of bus priority at traffic signals in the World; Bus priority at traffic signals: detailed case study of London; Comparative analysis and lessons learned; and Summary and future research.
