Abstract
From FY2021 to FY2022, as part of the Field Operation Tests (FOTs) in the Tokyo Waterfront area, an information delivery system that uses a public long range network (V2N) was set up and used to perform verification testing for four types of traffic environment information: rainfall information, lane-specific road traffic information, mock emergency vehicle information for vehicles on emergency calls, and predictive SPaT (Signal Phase and Timing) information. A total of 22 organizations from Japan and abroad participated in these FOTs. These included motor vehicle manufacturers, suppliers, venture companies, and universities. The participants evaluated the effectiveness of delivering traffic environment information via V2N and identified the issues that were involved. PUSH and PULL methods of information delivery were set up, to be used as appropriate given the characteristics of the information to be delivered. Participants evaluated the impact of increased communications traffic volume and the impact of delays caused by the network, looking towards future practical implementation. The results of the tests were evaluated and verified by test participants in FOTs working group meetings, and information regarding the effectiveness of traffic environment information and the issues involved were summarized.
