【摘要】 各股车流量所占份额、车流中车型的不同构成及交叉口的几何布置是决定非信号灯交叉口整体通行能力的3个要素．在3个要素的不同组合之下提出了计算通行能力的1个有效方法，并指明了提高交叉口通行能力的途径及设置信号灯的定量依据．更多还原

【Abstract】 Portion of each traffic flow, different ratio of vehicle type and the geometric design of the intersection are three important elements which decide the total capacity of unsignal intersection. This article provides an effective method to compute capacity with various composition of those three elements. Furthermore, it points out the path to improve the capacity of intersection and the quantitative warrant of setting traffic lights.更多还原
