【摘要】：为了探讨车型对城市道路并入型渐变段处交通流的影响,研究了大型车和小汽车在渐变段处并入主线的运动规律,以及对路段通行的影响.根据大小型车通过渐变段不同的加减速度以及排队规律,分析车辆通过渐变段影响区域的车均延误;根据不同大车率条件导致的通行能力差异,分析车辆通过渐变段影响区域的行程时间;建立了大型车和小汽车通过渐变段的延误模型和行程时间模型.以武汉市和平大道某并入型渐变段为例,利用VISSIM仿真平台验证延误模型和行程时间模型的有效性.结果表明,大车率的增加会对并入型渐变段的交通产生较大影响,使车辆的行程时间和平均延误增加.
[Abstract]:In order to study the influence of vehicle type on traffic flow at the gradual section of urban road, the law of movement of large vehicles and cars merging into the main line and the influence on the passage of road sections were studied. According to the different increasing and decreasing speed and queuing law of the small and large vehicles passing through the gradual change section, the delay of the vehicles in the area affected by the passing through the gradual change section is analyzed, and according to the difference of the traffic capacity caused by the conditions of the different vehicle rates, The travel time of the area affected by the gradual change of vehicle is analyzed, and the delay model and travel time model of the large vehicle and the car passing through the gradual section are established. Taking an integrated gradual change section of Heping Avenue in Wuhan as an example, the validity of delay model and travel time model is verified by using VISSIM simulation platform. The results show that the increase of the vehicle rate will have a great impact on the traffic of the subsumed gradual change section and increase the travel time and the average delay of the vehicle.
