Abstract

A risk prediction method, device and system for an occurrence of a traffic accident, which may achieve risk prediction of an occurrence of a vehicle traffic accident and improve accuracy of road traffic accident occurrence risk prediction. The method comprises: acquiring a surveillance video on a target road segment (S101); according to the surveillance video, acquiring video structural information (S102); according to license plate number information in the video structural information, querying vehicle status information and historical behavior information of each first vehicle on the target road segment in a preset database (S103); acquiring environmental condition information of the target road section when shooting the surveillance video (S104); according to historical information, vehicle status information and historical behavior information from an occurrence of a traffic accident on the target road segment as well as environmental condition information, determining a risk factor for an occurrence of a traffic accident for each first vehicle (S105); determining a risk factor as a risk prediction result for an occurrence of a vehicle traffic accident on the target road segment (S106).

Description

technical field [0001] The invention relates to the technical field of intelligent traffic management and control, in particular to a risk prediction method, device and system for traffic accidents. Background technique [0002] With the development of society, the number of motor vehicles in our country is rapidly expanding, and the frequency of road accidents is also on the rise. Effective prediction of specific road sections and vehicle risk states can reduce the incidence of traffic accidents and reduce the loss of people's lives and property, which has great practical significance and value. [0003] At present, the method for predicting the road accident risk on the target road section is specifically: collecting information on people, vehicles, roads, and the environment on the target road section in real time that affect the road accident risk; and predicting the risk status of the road accident on the target road section according to the collected information.
