An evaluation study on advanced public transport priority system using traffic simulation

ABSTRACT For the reasons of environmental issues, congestion mitigation, and vulnerable road users, the surface mass public transport (PT) system in urban area should be improved and promoted in Japan. This paper provides an overview of the current state of public transport priority system (PTPS) and the possibility of advanced PTPS. The effects of advanced PTPS by microscopic traffic simulation are estimated. As a result, it is found that advanced PTPS improves time reliability and transportability of buses, even if a congestion around an intersection occurs. The introduction of combination of bus lane and advanced PTPS improves time reliability and the transportability more. On the other hand, the introduction of bus lane reduces the acceptable volume of other vehicles because of reduction in the number of lanes for them. It is considered that the other users are also expected to shift to PT along with the PT level of service improvement.
