Right-turn collisions, collisions with pedestrians crossing streets, and crossing collisions at intersections account for an extremely large proportion of the accidents that occur in Japan, and 80% of these are caused by delayed perception and errors of operation or judgment on the part of the driver. This tendency can be expected to increase in the future as Japan's population ages, so measures to prevent intersection accidents are an urgent issue. Therefore Intersection Monitoring Sensor Systems have been developed that detect the behavior of vehicles and the crossing behavior of pedestrians in intersections and in the vicinity of intersections, with the objective of developing intersection accident prevention support services for the Advanced Cruise-Assist Highway System (AHS). Detection performance tracking tests of this system have also been implemented employing actual vehicles and pedestrians. This paper presents an overview of the prototype sensor system and test system, together with the results obtained from the testing and issues involved in deployment on actual roads.
