Abstract: Aiming at the lane problem in the cross intersection of two-dimensional traffic network with traffic lights, this paper puts forward a four-direction traffic model, and it includes the impact of acceleration parameters and change lanes probability on traffic flow, takes advantage of the methods of cellular automaton of BML model so as to simulate the whole dynamic process of vehicle, and points out the relationship between the critical point of lane changing probability and traffic flow influence. Numerical results show that the probability of lane change has disturbance impact on input and output traffic flow, and lane changing rules are correspond to the basic line of vehicles running.
