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.
