Abstract

According to the traffic conditions and the characteristics of traffic accidents on high-class highway in China, the outstanding factor method is put forward to analyze the black spots. When differentiating the black spots, the outstanding factors and composite factors are considered as the factors that cause the accidents if they are distinguished compared with other factors. The method is executed by two step. The first step is to choose the distinguished variables; the second one is to establish the mathematics model to analyze the result and draw a conclusion. The characteristic of the method is to pay attention to the influence of distinguished variables and neglect the influence of the undistinguished variables. The example of black spot is taken to analyze the factors that cause the accidents on the section of K343 + 800 m - K344 + 200 m of Shenda freeway. Field survey and observation prove that the results are right.
