摘　　要：从分析车道被占用对城市道路通行能力的影响出发,采用实测法,根据视频1中各个时间段三类车型统计出通过事故处的车辆数,绘制出各个时间段实际通行能力折线图,通过对折线图分析得出事故发生后各个时间段的变化情况,采用同样方法,将视频1和视频2的各个时间段的实际通行能力综合绘制到一个折线图中进行分析;最后,通过统计视频1中各个时间段的路段上游的车辆数目和车辆排队长度,建立了多元线性回归模型,运用SPSS19.0软件对交通事故所影响的上游路段车辆排队长度进行了分析。According to the analysis of the impact of lane occupiied on passing capacity of the urban road, the broke line graph of practical passing capacity at any time - points was drew out by practical measurement method based on the vehicle number of three vehicle types that passed accident site in video 1. The change situa- tion at any time-points after accident was obtained through analyzinti; the broke line graph. In the., same way, the actual passing capacity at any time -points in video 1 and video 2 was drew in a broke line graph and been analyzed. Finally, a multiple linear regression model was established based on statisticing the vehicle number in upper road section and the vehicle queue length in video 1. Moreover, the vehicle queue length in upper road section which affected by accident was analyzed using SPSS 19 software.
