To promote the realization of safe driving support and automated driving, it is essential to observe the conditions surrounding the vehicle, including beyond the vehicle's line of sight, and to provide vehicles with traffic information in real time that contributes to the prevention of traffic accidents using roadside sensors. Therefore, research and surveys were conducted into a system that provides vehicles with constantly changing traffic information using radio communication. In fiscal 2014 and 2015, research and surveys were conducted into the enhancement of driving safety support systems (DSSS) promoted by police, and the specifications of low cost versions of the systems, with the aim of implementing the systems across the country. In the following fiscal year of 2016, examinations were carried out with an eye toward the realization of automated driving. These involved the classification of traffic accident types and vehicle behavior at intersections, identification of the types of moving objects (vehicles, pedestrians, bicycles, and the like) that need to be detected, together with the required range of detection to ensure vehicle safety in each accident scenario, followed by an examination of the configuration of roadside sensors required for detection.
