Abstract
This paper presents an analysis of the crossing accidents caused by four-wheeled vehicles to each other at an intersection from a quantitative point of view using a detailed accident data. Based on the position of the roadside object and the danger perception speed, the database such as a grazing angle to another vehicle or the calculated perception distance were created, and it could reveal the various feature of crossing accidents. Furthermore, when reviewing the collision avoidance effect using the automatic braking, it was found that the detection angle of the sensor is as important as the relative position to another vehicle.
