The invention relates to a traffic accident real-time online simulation method and device. The method comprises the following steps: receiving first real-time sensing data of a roadside sensing system; performing traffic flow simulation of the preset road section based on the first real-time sensing data to obtain a simulated traffic flow; after the traffic accident information is received, second real-time sensing data of the roadside sensing system are received, the first real-time sensing data comprise real-time sensing data of a preset road section before the traffic accident occurrence moment, and the second real-time sensing data comprise real-time sensing data of the preset road section after the traffic accident occurrence moment; and based on the traffic accident information and the second real-time sensing data, simulating the driving behavior of the traffic participating object in the second real-time sensing data to obtain a first simulation result. According to the method, the real-time traffic participation object is taken as simulation input, so that the traffic situation of the preset road section in a short time under the simulated traffic accident is closer to the real situation, and the authenticity of the simulated traffic accident is improved.

    本申请涉及一种交通事故实时在线仿真方法及装置,该方法包括:接收路侧感知系统的第一实时感知数据;基于第一实时感知数据进行预设路段的交通流仿真,得到仿真交通流;在接收到交通事故信息后,接收路侧感知系统的第二实时感知数据,第一实时感知数据包括交通事故发生时刻之前预设路段的实时感知数据,第二实时感知数据包括交通事故发生时刻之后的预设路段的实时感知数据;基于交通事故信息和第二实时感知数据,对第二实时感知数据中的交通参与对象的行驶行为进行仿真,得到第一仿真结果。本方法中将实时交通参与对象作为仿真输入,使得仿真交通事故下预设路段在短时内的交通态势更接近真实情况,从而提高仿真交通事故的真实性。
