NICT REPORT 51Research HighlightsAn overview of intelligent transport infrastructure.An appreance of WETMand place it on a dynamic map to main-tain the road information.For the establishment of a roadway acquisition technology, NICT Wireless System Research Center (WSRC) re-searchers built a test-bed intelligent transport infrastructure in Yokosuka Re-search Park (YRP) utilizing the 5th gener-ation wireless communication system (5G) ultra-low latency to support autono-mous mobility in the roadway environ-ment as in the intersections. In addition, they developed a Wire-less Electronic Traffic Mirror (WETM) built-in camera and location measur-ing sensors that enable the collection of information on a variety of roadway situations such as road construction and vehicle congestion. This informa-“Under the test-bed infrastruc-ture, we have conrmed that it is possible to grasp the road-way situations in real time.”tion is then reflected on a dynamic map (DM), which is a database main-taining the roadway information, and is transmitted to the autonomously mov-ing vehicles, pedestrians, and so on. Kentaro Ishizu, research manager of the WSRC Wireless System Laboratory, stated, “Under the test-bed infrastruc-ture, we have confirmed that it is pos-sible to grasp the roadway situations in real time, especially an area in the vi-cinity of an intersection with poor visi-bility. From these achievements, we expect to construct an intelligent transport infrastructure to avoid mobil-ity collisions and to predict movement.” In the future, they will implement the 5G wireless communication system on the test-bed infrastructure and evalu-ate its performance with various wire-less systems in dierent roadway con-ditions such as when a large number of moving objects is located on a road-way and the moving speed of each is dierent or the area is wide. Dr. Ishizu also said, “We will confirm the func-tional requirements to be aimed at es-tablishing the technology to realize a more advanced autonomous transport system.”Dynamic mapEdge serverReal-time recognition of roadway situationsSnapshot by information acquisition
