Traffic Safety Evaluation Based on the Inherent Safety Principle

Abstract

Different from traditional safety studies which focus on the probability of accidents, inherent safety research takes one step further to judge the possibility of the inherent hazards. The method in the paper is necessary to analyze the risk of the urban road, especially it is necessary to avoid the traffic conflict or traffic accident’s occurrence on the aspect of the source. This paper built an evaluation index based on the inherent safety principle. The evaluation index consists of inherent people safety, inherent automobile safety, inherent road safety and inherent environment safety, and each aspect contains sub-indexes. Finally, the paper will quantify evaluation index which influence the traffic safety by the extension evaluation model. Based on the evaluation results, it was found that the traffic safety evaluation based on inherent safety is more reasonable and valuable.
