Abstract

The invention discloses a road risk assessment method based on an analytic hierarchy process, capable of solving the technical problem that the existing traffic pressure is high and difficult to control. The road risk assessment method comprises the following steps: analyzing road safety situation influence factors, and grading the safety situation factors; acquiring data of safety situation influence factors of the to-be-evaluated road; carrying out data preprocessing on the obtained data; calculating weight vectors of the road safety situation influence factors by utilizing an analytic hierarchy process; and calculating a road risk integral based on the weight vector of the road safety situation influence factor and the processed data, and evaluating the road risk according to the road risk integral. Through the application of hierarchical analysis in risk assessment, various risk factors and indexes appearing in the risk assessment process are analyzed, and the risk assessment integral model is established, so that a traffic department can analyze and control the current traffic situation, and the traffic control efficiency is improved, and the traffic risk coefficient is reduced.

Description

technical field [0001] The invention relates to the technical field of road traffic safety, in particular to a road risk assessment method based on the analytic hierarchy process. Background technique [0002] Because there are many factors affecting road traffic safety, the research on traffic safety situation is also a very important work. With the rapid development of society and economy in today's society, the level of motorization in our country is constantly improving, and the growth rate of motor vehicle ownership is too fast, which has caused urban traffic congestion and traffic accidents. And bring great hidden danger to people's traffic safety. Combined with the needs of actual traffic police management, establish a road control system to achieve efficient and precise management of police operations. [0003] Establish a risk assessment score model based on road traffic accidents, violations, traffic flow, weather and other relevant information. The lower the sco...
