The invention discloses a random traffic flow generation method and system, electronic equipment and a storage medium, and the method comprises the steps: constructing a collision trajectory model which can determine the speed and trajectory of a collision vehicle after a vehicle collision according to input parameters, and the input parameters are vehicle state data before the vehicle collision; embedding the collision trajectory model into a preset random traffic flow generation algorithm, and determining a target traffic flow generation algorithm; and generating a random traffic flow by using the target traffic flow algorithm. According to the invention, the technical problem that the microscopic interference of the traffic accident on the simulated vehicle cannot be simulated because the vehicle collision in the simulated traffic flow shows overlapping, passing and the like and does not conform to the vehicle collision behavior in the real traffic flow is solved.

    本发明公开了一种随机交通流生成方法、系统、电子设备及存储介质,其中,方法包括:构建碰撞轨迹模型,其中,碰撞轨迹模型可以根据输入参数确定发生车辆碰撞后的碰撞车辆速度和碰撞车辆轨迹,输入参数为车辆碰撞前的车辆状态数据;将碰撞轨迹模型嵌入预设随机交通流生成算法,确定目标交通流生成算法;利用目标交通流算法生成随机交通流。本发明解决了仿真交通流中的车辆碰撞表现为重叠、穿过等,不符合真实交通流中的车辆碰撞行为,进而无法仿真交通事故对仿真车辆产生的微观干扰的技术问题。
