摘　　要：以福清市玉融大桥及两侧桥头交叉口为研究对象,以桥面进口道上的95%排队长度和平均区间速度为交通效益的目标评价指标,应用Synchro和Vissim仿真优化软件对无信号控制、单点优化信号控制和协调优化控制系统进行设计优化及评价.结果表明:采用协调优化控制系统和单点优化信号控制系统后,95%排队长度分别比无信号控制减少了52.00%和49.85%,平均区间速度分别提高了30.78%和7.5%.由此可知,信号协调优化控制系统是比较理想的控制方式.Yurong bridge and its both-end intersections located in Fuqing City was set as research object, the 95% queue length and space mean speed were used as the evaluating indicators of traffic efficiency. With the application of ＂Synch.to＂ and ＂Vissim＂, de- sign optimization and evaluation of none signal control, single point control system, and optimizing coordinated control system were implemented. The results showed that a reduction of 52.00% and 49.85% for 95% queue length on the bridge could be achieved as well as 30.78% and 7.5% space mean speed could be increased respectively by using coordinated optimal control and single point optimal signal control. Therefore, the optimizing coordinated control system was regarded as a relatively ideal control method for the bridge and its beth-ond intersection.
