THE EFFECT OF VEHICLE PARAMETERS IN THE TWO-LANE CELLULAR AUTOMATA MODEL FOR TRAFFIC FLOW

Usually the traffic system is composed of different types of vehicles, which have different parameters. How these parameters, especially the length of the vehicles, influence the traffic behaviors and transportation capability has seldom been investigated. In this paper, we study this issue using the cellular automata traffic flow model. We find that when the road occupancy rate is large, increasing the ratio of long vehicles can improve the transportation capability apparently. We also discussed the influence of slow vehicles ratio on the average velocity of vehicles, it is found that the influences are very different when the difference of vehicle length is considered or not.
