摘　　要：运用VISSIM对无信号环形交叉口以及有信号十字交叉口的通行延误情况进行模拟仿真。以车均运行延误时间、车均停车延误时间、车均停车次数以及排队长度为评价指标,分析对比两种不同形式的交叉口在不同输入交通量水平下的通行状况,最终确定两种不同形式交叉口的输入交通量的临界值。In this paper, the traffic delays between unsignalized roundabouts and signalized crossroads were simulated using VISSIM. The evaluation indexes were the average running delay time, the average stopping delay time, the average stopping times and the queue length. The traffic conditions between the two types of intersections under different levels of input traffic loads were analyzed and compared to determine the critical value of input traffic loads.
