Research on urban road traffic safety evaluation based on the combined weight topsis method

Abstract

: In this paper, an index evaluation system on traffic safety is constructed based on accident indicators and hidden danger indicators, combined with the AHP-EMW combined weight method for index weight analysis, which effectively solves the influence of subjective extremum deviation on weight accuracy, and uses the Topsis method to conduct traffic safety evaluation on 10 urban roads, conducts case verification, and proposes suggestions and measures to improve urban road traffic safety according to the evaluation results, providing a certain reference for the research of urban road traffic safety.
