Town highway traffic safety analysis and evaluation method under bad climate conditions

Abstract

The invention discloses a town highway traffic safety analysis and evaluation method under bad climate conditions. The method comprises the following steps of S1, carrying out urban highway traffic safety analysis under bad weather conditions; S2, establishing a town highway traffic safety evaluation index system under bad conditions; S3, carrying out urban highway traffic safety evaluation modelresearch under bad conditions; and S4, performing analysis and verification through examples, and proving that the obtained and established urban highway traffic safety evaluation index system is relatively high in feasibility and practicability under the bad climate conditions, and providing relevant improvement suggestions aiming at the defects and the hidden danger. According to the method, thetraffic safety problem existing in urban highway under poor conditions is solved, and the method is practical from urban roads, and various factors influencing traffic safety of urban highways underbad climate conditions are comprehensively considered; and a qualitative and quantitative combination analysis method is adopted, the weight is determined by a hierarchical analysis method, and fuzzycomprehensive evaluation is adopted for the safety of the objective conditions, so that a set of traffic safety evaluation index systems and evaluation methods suitable for urban highway characteristics under bad climate conditions are established.

Description

technical field [0001] The invention relates to the technical field of traffic safety analysis and evaluation, in particular to a method for analyzing and evaluating urban road traffic safety under bad weather conditions. Background technique [0002] With the continuous deepening of my country's urbanization process, the roads that used to play a connecting role, with the increase of urban population and number of cities, the expansion of urban scale and the improvement of urban economic socialization, modernization and intensification, its function and role It is gradually changing to urban roads, which has the characteristics of both highways and urban roads. [0003] Due to the fact that urbanization not only undertakes the transit traffic pressure in the urban section, but also undertakes a part of the internal traffic of the cities and towns passing through to meet the travel requirements of passengers, goods, slow trains and pedestrians in the town, and even many roads...
