Construction and Application of Highway Safety Evaluation System Based on Traffic Ergonomics

Recently, with the increase in traffic accidents, more and more attention has been paid to road safety. Traffic ergonomics is the focus on improving the coordination among people, vehicles, and road environments from the angle of traffic participants based on ergonomics. In this paper, by the theory and method of traffic ergonomics, a variety of factors that affect highway safety were analyzed and summarized to establish a highway safety evaluation system based on traffic ergonomics. The evaluation system contains a level one indicator and four level two indicators, and there is a summary of the contents for each of the level two indicators. Finally, an accident-prone segment of Badaling Expressway was taken for example. There were analyses of reasons for accidents and measures for improvement based on the highway safety evaluation system.
