The invention discloses a motorcade traffic flow simulation method considering congestion wave travel time randomness. The method comprises the following steps: 1) setting simulation related parameters (the number of vehicles in a motorcade, initial positions of the vehicles, head vehicle information, simulation duration, an output range, driver related parameters and the like); 2) judging whetherthe simulation time exceeds the required simulation duration or not, if not, sequentially updating from front to back according to the motorcade sequence, and if yes, stopping; 3) updating the stateof the head vehicle; 4) updating the non-head vehicle state; 5) judging whether the data of the currently updated vehicle needs to be output or not, and if so, outputting the data of the current vehicle at the moment; 6) judging whether a rear vehicle exists or not, if so, extracting the number of the rear vehicle, and repeating the step 4); if the rear vehicle does not exist, the next step is executed; 7) updating simulation time. According to the method, the randomness of crowded wave travel time is considered, and the method can be used for simulating and reproducing actual traffic conditions.
本发明公开一种考虑拥挤波旅行时间随机性的车队交通流模拟方法。步骤:1)设置仿真相关参数(车队内车辆数,车辆初始位置,头车信息,仿真时长,输出范围,驾驶员相关参数等);2)判断仿真时间是否超过所需仿真时长,若没有,则按车队顺序,从前往后依次更新,若超过,则停止;3)更新头车状态;4)更新非头车状态;5)判断是否需要输出当前更新车辆的数据,若需要,则输出该时刻当前车辆的数据;6)判断是否存在后车,若存在,则提取后车的编号,重复步骤4);若不存在后车,则下一步骤;7)更新仿真时间。该方法考虑了拥挤波旅行时间的随机性,能够用于对实际交通状况的模拟与再现。
