Advanced vehicle probe data collection devices installed in Toyohashi City official vehicles identify potential pedestrian accident hazard spots

The Advanced Vehicle Probe Data Collection System (“a-probe”) accumulates real-time collision prevention warning data for pedestrians and vehicles in the cloud, along with the location and time of the driving vehicle, as well as speed sign data and other information captured from camera images. By analyzing this data and combining it with various other factors such as the number of lanes on the road, intersections, residential conditions around the road, and traffic volume, we can efficiently and accurately identify potential roadway hazard spots.

The installation of this “a-probe” on 50 Toyohashi City official vehicles was completed in March 2020, and the data has been accumulating daily since then.

The data analysis technology developed by Associate Professor Kojiro Matsuo at TUT has made it possible to not only identify pedestrian accident risk points, but also to create detailed maps of road speed restrictions. The City of Toyohashi will use this data analysis-based road-traffic safety management system to promote a safer city with the goal of zero traffic accidents. J21 Corporation based in Toyohashi Japan, the partner in charge of developing this “a-probe”, is leading the commercialization of the "Traffic Safety Management System with Advanced Probe Data" model.
