The invention discloses a traffic safety early warning analysis method and device. The method comprises the steps: obtaining the traffic data of a target region in a preset time period and the feature data of a target object; and determining a plurality of primary influence factors, a plurality of secondary influence factors and evaluation scores of the plurality of secondary influence factors on the basis of dynamic and static angles in combination with the data, then determining the importance degree of each level of influence factor, calculating to obtain a traffic safety early warning degree, and generating a traffic safety early warning analysis result. According to the invention, the problem that accurate traffic early warning prompt cannot be provided for a user in the prior art is solved, the traffic accident risk of an intersection can be evaluated more systematically, comprehensively and visually, and traffic early warning prompt can be carried out accurately; and by judging a matrix, the importance degree of each index is determined, the safety risk of the intersection can be quantitatively represented, and accurate risk early warning can be carried out on pedestrians and vehicles on branches.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to a traffic safety early warning analysis method, device and computer equipment. Background technique [0002] With the rapid development of the economy and society, the road mileage continues to increase, and the number of motor vehicles continues to increase. The traffic safety situation cannot be ignored, especially at the openings of urban roads, the intersection of rural branch roads and national and provincial roads, and sharp bends. Insufficient safety awareness of traffic participants and other factors lead to frequent traffic accidents. In the existing traffic early warning technology, guardrails, indicator lights and various protective measures have been set up, but the frequency of traffic accidents remains high at the above-mentioned road sections. Therefore, how to provide users with accurate traffic early warning prompts has become a problem. Problems to be ...
