公交车与社会车辆混合行驶下的交通流模型研究
Study on Traffic Flow Models Based on Mixed Motor Traffic with Buses
【摘要】 速度在交通流模型中通常定义为路段车辆的平均行驶速度。但是当路段上社会车辆与公交车辆混合行驶时,社会车辆的平均速度往往要高于公交车辆的平均速度,如果将路段所有车辆的平均行驶速度作为公交车辆的平均速度或社会车辆的平均速度是不合理的。因此,通过对实测数据的分析,本文分别建立了公交车辆与社会车辆的速度模型,这两个模型为正确地分析路段车辆的运行状态、合理地计算车辆路段行驶时间提供了参考。
【Abstract】 Velocity in the traffic flow models is defined as the average velocity of all vehicles on the road.The average velocity of general vehicles is faster than that of buses when buses and other vehicles are mixed together.So it is not reasonable to use the average velocity of all vehicles to replace the velocity of buses or that of other vehicles.For that reason,the velocity model of the mixed motor traffic established separately in the article based on the analysis of survey data.These models are useful for analyzing correctly running state of vehicles and estimating rationally running time of vehicles.
