摘　　要：有轨电车交叉口信号优先控制策略,在保证不影响交叉口整体通行能力的前提下,使得有轨电车优先通过交叉口。利用VISSIM工具,对无信号优先,绝对信号优先和条件信号优先控制下的有轨电车交叉口进行模拟和评价,验证信号优先和条件信号优先控制策略的适用性。通过仿真得出结论,若给予有轨电车最高的优先权,使有轨电车平均延误时间最小,停车次数为0,采用绝对信号优先控制策略较好;若在基本上不影响整个交叉口的平均延误和服务水平的情况下给予有轨电车信号优先,采取条件优先信号控制策略较好。This paper studied on the signal priority control strategy of trams intersection to make the tram priority in the intersection under the condition that the overall trafc capacity was not afected, carried out the simulation and evaluation of tram intersection without signal priority, absolute signal priority and conditional signal priority control by using VISSIM tools, verifed the applicability of signal priority and conditional signal priority control strategy. The conclusion is drawn by simulation that： if the tram is the highest priority, the average delay time of trams is the minimum and the number of stops is 0, the absolute signal priority control strategy is better. If the average delay and service level of the intersection are basically not afected, the tram signal priority is given, and the conditional priority signal control strategy is better.
