The Research Of Multiple Point Identification Method In Non-signalized Intersection Accident

Traffic safety problem has already become a focal point of the whole society, although the researches about that are increasingly mature, there are still many local needs further study. The paper is based on this background.Firstly, this paper researched the influence factor of intersection traffic safety without signal. In this section, combined with the properties of non-signal intersection, the research finally pointed out the non-signal intersection traffic safety factor, through the study on the common impact of traffic safetySecondly, this paper compared common identification methods of accident-prone points. In this section the common existing traffic black-spot identification method was generally introduced, and after analyzing the shortcomings and suitability of each method, the paper proposed the non-signal intersection traffic black-spot identification method.Again, considering the defects of traditional traffic black-spot identification methods, this paper mainly studied the defects of the conflict based on traffic non-signal intersection traffic black-spot identification method. Through the analysis of basic traffic conflict theory and the properties of non-signal intersection traffic conflict, this section established the non-signal intersection traffic conflict evaluation model.Finally, the paper chose the roads and urban road intersection to analysis, according to the result of this research.
