中文摘要：
针对以往基于Webster和HCM信号配时优化方法的缺点,提出了一种基于信号灯组、考虑行人和自行车绿灯间隔约束、使用微观仿真多种评价指标作为优化目标的单点固定信号优化方法,并且提出了模型求解算法。然后使用VC＋＋调用VISSIM的COM接口对一个实际四叉路口分饱和和非饱和条件下做大量仿真试验,根据仿真结果对得出模型的有效性及一些有价值的结论。
英文摘要：
In order to modify disadvantages of Optimization methods based on Webster and HCM, a model for optimization of pre-timed signals at isolated intersections was established which was signal group-based, considering pedestrian and bicycle intergreen time constrains, using the MOE＇s of VISSIM Micro-Simulation as optimization objectives, And the optimization arithmetic was also put forward. Then a series of simulation test were conducted on an isolated pre-timed four-leg intersection under both under-saturated and saturated conditions. According to the simulation result, the availability and affectivity of the model and the some valuable conclusions were given.
