The invention discloses a traffic flow simulation method based on road average speed, and the method comprises the following steps: reading a map model needing to be simulated, and converting a file of the map model into a configuration file which can be directly read and used by traffic microscopic simulation software; generating a driving path of the vehicle in the simulation software by utilizing the configuration file; calculating an expected vehicle speed of the road section; checking the to-be-updated speed queue according to a preset updating frequency, and if a to-be-updated speed value exists in the to-be-updated speed queue, smoothly updating the simulation vehicle speed in the traffic microscopic simulation software; the method has the advantages that the simulation vehicle speed of the simulation environment can be smoothly updated, the simulation effect is more real, and instantaneous speed change of the vehicle at a certain time point is avoided; and during cyclic departure, the road selection of the vehicle is more reasonable, and the simulated flow of the road section can be more conveniently controlled.

    本发明公开了一种基于道路平均速度的车流仿真方法,包括如下步骤:读取需要模拟的地图模型,将地图模型的文件转换为交通微观仿真软件能够直接读取和使用的配置文件;利用配置文件,生成仿真软件中车辆的行驶路径;计算路段的期望车辆速度;根据预设的更新频率检查待更新速度队列,若待更新速度队列中有待更新的速度值,则平滑更新交通微观仿真软件中的仿真车辆速度;本发明具有能够平滑更新模拟环境的仿真车辆速度,模拟效果更加真实,不会使车辆在某一时间点瞬时变速;循环发车时,车辆的道路选择更加合理,路段的模拟流量能更方便地控制的特点。
