摘要： 为了提高桥头交叉口的通行能力以及减轻桥梁的承重力，提出了基于机动车比功率（VSP）环境影响因素和排队长度的交叉口信号配时优化方法；建立以减少排放和降低排队长度为总目标的信号交叉口优化模型，使用Matlab进行代码编程求解，达到优化信号配时之目的；并以福清市玉融大桥南侧桥头交叉口实例进行验证，结果发现：在晚高峰阶段，交通总排放量降低11.5%，桥上排队长度降低16.1%。

Abstract： In order to improve the traffic capacity of the intersection and reduce the bearing capacity of the bridge, the optimization method of intersection signal timing is proposed based on the vehicle specific power (VSP) and consider the environmental factors and queue length. First, establish a traffic signal control model for reducing emissions and shorting queue length, and use Matlab to solve, then optimize the signal cycle and the length of the green light. Finally, verify to the model with the bridge intersection on the south side of YuRong Bridge. And results find: in the late peak period, the traffic emissions were reduced by 11.5%，and the length of queue was reduced on bride by 16.1%.
Keywords： kSignal timing; low emission; queue length; motor vehicle specific power; traffic simulation
