ABSTRACT
To solve the problem that the common safety distance models cannot simultaneously take into account of warning distance and traffic efficiency, an optimized model of minimum safety distance of car following was established, which considered 12 situations of car following. The new model which had the additional analysis of the leading vehicle in uniform deceleration condition and canceled the ideal assumptions that the velocity of vehicle brake in driver response decision stage and operation stages is uniform, included 7 dangerous situations when the leading vehicle in uniform speed, uniform deceleration and emergency braking driving states. The Matlab simulation indicated that the optimized model got a smaller warning distance in common situations and got a longer warning distance in extremely dangerous situations. The optimized model, not only ensured traffic safety and improved the traffic efficiency.
