针对交通事故发生后道路实际通行能力的变化过程,以车流量为切入点,综合运用理论分析法和假设检验,并借助于视频和图像,建立交通量模型和实际通行能力模型,运用Matlab、C语言等软件,得到了事故所处横断面实际通行能力的变化情况和最终车辆排队长度到达上游路口的时间约为8min等结果。 Aiming at the changing process of the actual traffic capacity of the road after the traffic accident, taking the traffic flow as the breakthrough point, the theoretical analysis and hypothesis test are used synthetically. With the aid of video and image, the traffic volume model and the actual traffic capacity model are established. Language and other software, get the cross section of the accident where the actual capacity of the changes and the final vehicle queue length reaches the upper reaches of the time is about 8min and other results.
