Abstract: The car-following behavior was studied by molecular kinetics, the required safe distance was explored and an application model was built. By giving the reaction weights to various stimuli, a state equation for the isodirectionality of the responses of the driver to various stimuli was derived using the mathematical deduction. Based on this equation, a molecular car-following model was built to describe the car-following behavior. The results of analyses from the data validation and the experimental comparison showed that the proposed molecular car-following model describes the car-following behavior more completely and appropriately, makes up the deficiency of the speed-based car-following models, and improves the car-following theory.

Key words: engineering of communications and transportation system, traffic flow theory, car-following behavior, molecular kinetics, required safe distance
