摘　　要：结合菱形立体交叉口的特点,运用车队分析法、间隙接受理论及相关的规范标准,对菱形立体交叉口内两个无信号平面交叉口的最小间距进行了分析,得出三个组成部分:从主路上出来的转弯车辆在次要道路上的最小停车排队长度和在次要道路上的最小变换车道长度,以及两平面交叉口的最小净距。对三个组成部分进行分析,建立了其理论模型。通过实例分析,结果表明了模型的正确性,同时有助于菱形立交的规划、设计、建设和管理。This paper analyzes the least space among the non-signalized at-grade intersections in the diamond interchange combined with the characteristics of the diamond interchange using queuing theory and gap acceptance theory.There are three constituting parts: the shortest parking queue on the subordinate road from the main road,the shortest length of changing road on subordinate road and the net space between the two at-grade intersections.The authors analyze the three parts and finally educe the theoretic model of the space. This model is confirmed by an example,and is helpful for the engineering practice of diamond interchange,such as layout,design,construction and administration.
