摘要
针对车道被占用对城市道路通行能力的影响,根据视频1、2采集数据并进行标准化处理,借助拟合程度R2检验、F检验、t检验等方法,分别建立实际通行能力变化规律、不同车道实际通行能力差异、多元线性回归、微分方程等模型,使用Excel、Matlab7、Eviews6等软件,得到交通事故发生至撤离期间,事故所处横断面实际通行能力的变化,同横断面交通事故所占车道不同对其实际通行能力影响的差异,以及路段车辆排队长度与事故横断面实际通行能力、事故持续时间、路段上游车流量间的相关关系。
According to the standardized data collected from Video 1 and 2, and with the methods such as R2 - square test, F - test, t - test etc. , the study establishes the actual capacity model of the change rule, the different actual model of the capacity of different lanes, muhivariable linear regression model, and the differential equation model. The adoption of the software Excel, Maflab7 and Eviews6 works out the accident cross - sectional changes in actual capacity, the influence of traltlc accident occurring in the same cross - section of different lanes on its actual capacity. At the same time, the relationship between road vehicle queue length and the actual capacity of the accident cross - section, the duration of the accident and upstream flow are revealed as well.
