Performance evaluation of vehicle cooperative driving assistance systems that uses forward obstruction detecting sensors and inver-vehicle communication

This paper describes a evaluation of the safety performance of a vehicle cooperative driving assistance system that uses forward obstruction detecting sensors. The information acquisition rate is defined as the ratio of number of information acquisition vehicles to number of vehicles of and others in surrounding that exists in constant range to have centered on the subject vehicle and evaluated it by microscopic traffic simulation. Furthermore safety performances of the driving assistance system have been evaluated by microscopic traffic simulator from the viewpoint of a road administrator and drivers. Results of simulation have been indicated that the system that uses only the forward obstruction detecting sensor achieves the same safety-performance as the combinations system by improving penetration from 10 to 30 points.
