摘　　要：针对斜交十字交叉口存在的安全隐患等问题,提出为锐角进入交叉口的次路车流设置车辆待行区,使支路车流可以分两个阶段通过交叉口.以一级公路为例,运用概率论和排队论计算了车辆待行区所适应的交通量范围,给出了通行能力的计算方法.在不同交通量情况下,比较了普通让行、信号灯和设置车辆待行区三种交叉口控制方式的延误.Aiming at traffic disorder and safety problems at skew intersections, the paper puts forward a new idea setting vehicle-waiting area for entry vehicles from an acute angle, which can make spur track vehicles across the intersection by .two phases. Take the arterial road for example, with the methods of probability and queue theory, it educed the appropriate tm^c range for vehicle-waiting area, presented the formulae of capacities. On different traffic conditions, it compared the delays of three kinds of intersection control types： yield, signalized and intersection with vehicle-waiting area.
