Characteristics of Collision Accident at Unsignalized Intersections in Aichi Prefecture

Abstract

In Japan, the number of traffic accidents is decreasing, but the number of the intersection collision is increasing. Previous research has confirmed that ``large number of branches'' and ``land use'' have an influence on collision accidents at unsignalized intersections. However, in order to consider safety measures, it is necessary to understand the number and structure of unsignalized intersections. Therefore, in this study created unsignalized intersections using open data for Aichi prefecture. The number of unsignalized intersections and the shape of intersections were collected, and the characteristics he intersection collision by age were tabulated. As a result, it was found that there was a difference between the ranking of the number of accidents and the ratio of the number of intersections, and that the ratio of accidents at deformed intersections was higher when looking at the ratio of intersections. In the future, aim to add intersection space factors and build a model for the occurrence of collisions at intersections.
