摘要

Different types of drivers usually take on different driving tendency on urban road, based on the diversity of driving tendency, a new two-lane cellular automaton model was proposed under condition of periodical boundary. The mean speed, flow volume and lane-changing frequency under different lane-changing and deceleration rules were simulated. In the process of computational simulation, the fundamental diagrams of traffic flow under different rules were obtained by changing traffic flow density. Simulation results show that the proposed new rules can improve traffic flow volume and suppress traffic jam to a certain degree. Finally, the critical points were discussed to show the impact of lane-changing on traffic flow.
