Study on improvement of information entropy weight multiple objectives decision method and its application in safety evaluation of highway traffic

Abstract

The safety evaluation management of highway traffic project is generally a complex problem which is affected by many factors. Safety evaluation indexes, methods and steps are very worth studying. Aiming at this problem, this paper selects three typical suburban roads to establish the evaluation indexes of road traffic safety, and evaluates their safety levels by an improved entropy weight multiple objectives decision making method presented in this paper, and gives some practical suggestion of how to improve according to the evaluation results. Compared with other references, Presents method can comprehensively consider objective information provided by the practical system and subjective judgment of experts. These can offer the reference for multiple objectives safety evaluation management of highway traffic project.
