【 摘 要 】

To study the influence of cross-street pedestrian on the urban traffic flow, traffic characteristic of vehicle and pedestrian are investigated under horizontal interference conditions. With resetting the rules of vehicle operation behaviour such as deceleration, acceleration, lane change, etc, a new simulation model of two-lane urban traffic flow is established, which is also called cellular automata model. To simulate the traffic conditions of signal control road sections and non-signal control road sections and generate the space-time diagram, the softwares MATLAB and ORIGIN is used for acquiring numerical simulating results and relational graphs of the traffic flow parameters. Comparative analysis is carried on between traffic state with horizontal interference and traffic state without horizontal interference. Finally, simulation results show that pedestrian crossing street has less obvious impact on traffic flow in larger density (higher than 0.22), signal control and acceptable crossing gaps for pedestrian have certain influence on traffic flow and lane change of vehicle. The proposed simulation model is in better consistence with actual situation and has some practical and theoretical significance for traffic flow research.
