The police in Japan have launched the "Police ITS Project: UTMS (Universal Traffic Management Systems)" to promote domestic ITS and are promoting a variety of polices to make this practical. As part of the "Police ITS Project", the Metropolitan Police Department is building the Public Transportation Priority System (PTPS) as a subsystem of UTMS. The PTPS is a system that conducts priority signal control (green extension or red shortening) for buses. The purpose of this test was to investigate and verify the following four points regarding the centrally controlled priority control that was newly added to terminal sensing priority control also used by PTPS and was implemented on the two routes of Meguro Boulevard and Koganei Road - Takiyama Chuo Boulevard: (1) Verify the bus priority signal control method; (2) Verify the effects of PTPS introduction on traffic volume, traffic congestion duration, travel time, etc.; (3) Verify the bus route schedule accuracy; and (4) Survey the degree of bus awareness. In addition, these two routes were selected because they are heavily used as major thoroughfares through the metropolis and because many buses for several bus routes use these routes. This paper reports the results of the effectiveness verification test conducted for this project. This project is a model for the widespread implementation of ITS in Japan and the results are expected to serve as an indicator for future PTPS implementation.
