Simulation on Influencing of Lane Changing Probability on Traffic Flow Base on Cellular Automata

摘要

Simulation of traffic flow is a complicated system engineering that is influenced by multitudinous factors. A four-direction traffic flow model have been put forward considering parameters of acceleration and probability of lanes changing impacting on traffic flow. On that basis, stability of traffic flow was analyzed. Finally, two dimensional cellular road model in symmetrical type have been carried out to simulate in order to testify validity and applicability, and Origin 6.1was applied to analyze effect of probability of lane changing and acceleration on traffic flow under open boundary conditions. The results show that traffic flow and lane changing probability fluctuates, traffic flow of exit is 2.49±0.1, traffic flow of entrance is 2.2±0.1, traffic flow of exit and entrance keep value area of 1.8±0.1.
