The invention discloses a microscopic traffic simulation method for unmanned and manned mixed traffic flow. The simulation method comprises the steps of receiving a simulation request of the unmannedvehicle and manned vehicle mixed traffic flow; based on a microscopic traffic simulation platform, constructing a traffic simulation scene according to the simulation request, and setting traffic simulation scene parameters; according to the traffic simulation scene parameters, setting the proportion of the unmanned vehicle or specifying the initial appearance serial number of the unmanned vehicle, and configuring vehicle following, lane changing and overtaking model parameters of the unmanned vehicle; inputting the driving related parameters into a preset microscopic traffic simulation program for traffic simulation, and outputting a simulation result; and carrying out traffic safety evaluation and traffic efficiency evaluation based on the simulation result. According to the method, a simulation research basis can be provided for going-on of the unmanned vehicle, and the defect that an existing traffic simulation platform cannot achieve traffic simulation of mixed driving of large-scale unmanned vehicles and manned vehicles is overcome.

    本发明公开了一种无人驾驶和有人驾驶混行交通流的微观交通仿真方法,该仿真方法包括:接收无人驾驶车辆与有人驾驶车辆混行交通流的仿真请求;基于微观交通仿真平台,根据仿真请求构建交通仿真场景,并设置交通仿真场景参数;根据交通仿真场景参数设置无人驾驶车辆的比例或者指定无人驾驶车辆的初始出现序号,并配置无人驾驶车辆的跟车、换道和超车模型参数;将驾驶上述相关参数输入预设微观交通仿真程序中进行交通仿真,并输出仿真结果;基于仿真结果进行交通安全评价和交通效率评价。该方法能够为无人驾驶车辆的上路提供仿真研究基础,弥补了现有的交通仿真平台无法实现大规模无人驾驶车辆和有人驾驶车辆混行的交通仿真的缺陷。
