Abstract

Since the evaluation of traffic safety status of urban road intersections is fuzzy and hierarchical, this paper analyzes the occurrence mechanism of traffic accidents at urban road intersections, constructs an evaluation index system for smart traffic safety status of urban road intersections, and proposes an index system based on the analytic hierarchy process and fuzzy theory. Smart traffic safety evaluation method at urban road intersections. The fuzzy theory is used to modify the weights calculated by the analytic hierarchy process to obtain the membership value of each indicator in the evaluation system, and the fuzzy comprehensive evaluation results of the traffic safety status of urban road intersections are determined based on the principle of maximum membership. The study takes an intersection in Chongqing Hi-tech Zone as an example, and uses the index system and fuzzy comprehensive evaluation method in this article to evaluate its traffic safety status. Comparing the results with the actual results, it was found that the two are basically consistent, which verifies the effectiveness of the index system and evaluation method proposed in this article, and can provide reference and reference for the smart traffic safety evaluation of urban road intersections.
