Development of Intersection Safety Support Systems using Vehicle-To-Vehicle Communication

Abstract

The development of systems that enable a vehicle itself to detect a dangerous situation and to support the driver's accident avoidance maneuvers is gaining momentum as a result of the progress being made in sensors for detecting the forward environment and in actuators for controlling the vehicle's driving and braking forces. The systems now under development mainly envision emergency situations leading to rear-end collisions. In order to reduce traffic accidents, there are needs for systems that are effective in avoiding intersection crashes, which are typical of the types of accidents that occur in Japan and are as numerous as rear-end collisions. However, reduction of right- and left-turn accidents or broadside accidents at intersections would not be easy to accomplish with autonomous support systems in individual vehicles. This paper focuses specifically on accidents at intersections and examines approaches to reducing such accidents by means of vehicle-to-vehicle communication.
