摘　　要：文章通过多元统计分析,得到了中小城市典型交叉口(无控与信号交叉口)的机动车平均延误随机动车排队长度与机动车、非机动车流量变化的规律,并提出了实用且相关性很高的无控与信号交叉口延误的计算列式,可用来有效评价和预测交叉口处机动车延误。By the method of the multivariate statistical analysis, for the typical intersections (the non-control and the signalized intersections) of the small-and medium-sized cities, we can obtain the variety regulation of the mean vehicle delay with the vehicle queuing length and the traffic flow of the motorized and the non-motorized vehicles. Thus the practical and the highly correlative calculation expression is put forward according to the above two intersections, which can be applied to estimate and forecast the vehicle delay of the intersections effectively.
