利用交通事故再现软件PC-Crash,提出了一种具有动力学响应输出的避险车道事故三维仿真方法。该方法使用经典的贝克理论作为模拟制动床集料特性的理论模型。详细提供了利用PC-Crash再现避险车道事故的7大步骤,讨论了其中的关键问题;给出了不同参数组合下避险车道制动床所需长度的试验结果,最后介绍了一个工程应用案例。此方法主要用于直观、定量地测试避险车道的坡度、长度、集料特性等参数,或三维再现具体的避险车道事故过程。
Using PC-Crash, a traffic accident reproduction software, a three-dimensional simulation method for haz- ing lane accidents with dynamic response output is proposed. This method uses the classical Baker’s theory as a theoretical model for simulating the characteristics of a bed of brake shoes. The seven major steps of using PC-Crash to reproduce the safe-haven lane accident are discussed in detail, and the key problems are discussed. The test results of the required length of the harsh-bed brake bed with different parameters are given. Finally, an engineering application Case. This method is mainly used to directly and quantitatively test the parameters such as the slope, length and aggregate characteristics of hedging lanes or to reconstruct the specific safe haven accident process in three dimensions.
