摘要
以元胞自动机理论为基础,建立兰州快速公交系统元胞自动机仿真模型.仿真研究了周期性边界条件下,兰州快速公交车辆在不同行车密度、不同路况及驾驶员行为差异下随机慢化对快速公交车流的影响,得到相应的定量分析结论.通过对兰州快速公交系统进行仿真与分析,研究BRT交通流的复杂特性,从而为后期兰州快速公交系统的运营与管理提供科学的理论依据.
Influence of Bus Rapid Transit system is significant on the city＇s traffic.Currently,The Bus Rapid Transit system is building in Lanzhou city to solve the serious traffic problems.In this case,a model of Lanzhou BRT cellular automata is presented based on NS traffic model.Effect of BRT vehicle randomization in different traffic density,different road condition and driver＇s behavior on bus rapid traffic flow is studied under periodic boundary conditions.The purpose is to get the result of corresponding quantitative analysis conclusion.The complex characteristics of Lanzhou Bus Rapid Transit traffic system are studied by modeling and simulation so as to provide scientific theory for Lanzhou Bus Rapid Transit operation and management later.
