摘　　要：在现代有轨电车工程设计中需要对平面交叉口的延误时间进行分析,一般较多采用仿真的方法得出交叉口延误时间,但这对交通量数据可靠性要求较高.避开了交通流量调查这一环节,首先分析了交叉口信号优先的约束条件,然后采用概率论方法得出了单列车的延误时间,并推广至两列车的情形,研究成果提供了一种计算交叉口延误时间的方法,可为有轨电车前期行车组织设计提供参考.In modern tram engineering design, the delay time of intersection should be analyzed. Other researches generally use the method of simulation to obtain the intersection delay time, which will lead to the higher requirements of reliable traffic flow data. So this article avoids the link of traffic survey, first of all analyzes the intersection signal priority constraints,and then obtained the delay time of one train by using the method of probability theory,and then promote to two trains situation. This research provides a method of computing the intersection delay time of tram which will provide reference for tram operation organization design.
