| 摘 要： | 研究了环形交叉口通行能力与服务水平，在建立通行能力理论模型的基础上，详细阐述了环形交叉口总的基本通行能力的计算方法，得出了三种典型环形交叉口的总的基本通行能力，分别为2700辆／h,3600辆／h和4100辆／h，建立了以车辆平均延误为指标的服务水平划分方法，并根据延误与饱和度的关系计算出三种典型环形交叉口在各服务水平下的总的服务通行能力。

| Abstract: | The capacity and the levels of service of roundabout are studied. Based on the theoretical models, a suitable methodology calculating the total basic capacity of roundabout is discussed, and the calculated results of three typical kinds of roundabouts are expounded. The total basic capacities of three typical roundabouts are 2?700?pcu/h, 3?600?pcu/h and 4?100?pcu/h, respectively. The level of service is described in term of the average delay of vehicles. The total service capacities of three typical kinds of roundabouts at different levels of service are calculated according to delay saturation curve. |
