The distance from a vehicle to an obstacle is one of the most important factors in preventing traffic accidents. A collision happens when this distance is smaller than the stopping distance. All collisions are caused by a shorter length of distance from a vehicle to an obstacle. The essential thing is that drivers must keep enough distance from obstacles because stopping distance changes easily. A system was developed that records the distance from a vehicle to obstacles, the velocity, and location during driving. This system has a graphical window that shows a superimposed run trace on a map. It also presents graphs of the distance from the vehicle to obstacles and the velocity at the arbitrary spot. By using this recording system, the driver knows whether the distance from his/her vehicle to the obstacles is enough or whether he/she has stopped at the necessary spot and so on. It is considered that the feedback education of a driver's actual behaviour was effective for the improvement of a person's stopping behaviour at an intersection. The experimental results suggested that drivers came to stop more frequently and for a longer time at no signal intersections after the feedback education with the use of a recording system.
