混合交通流条件下信号交叉口配时优化设计

Design of Timing Optimization under the Mixed Traffic Flow in Signal Intersection

运用适合我国交通现况的定时式线控制系统理论,以南京市太平北路与珠江路的十字典型交叉口为例,在现状调查分析的基础之上,具体分析信号配时方案产生的全过程,提出使城市道路单点信号控制交叉口的时空资源得到综合优化利用的交叉口车道渠化方法和信号配时优化方法,并应用交通仿真模拟软件VISSIM对交叉口配时方案进行模拟,将优化方案与现状进行比较,取得了较好的结果。

The paper applies the timing linear control system theory which fits the present traffic situation in China.Then typical cross intersection is taken as an example at the Taiping north road and Zhujiang road,city of Nanjing.Based on the field investigation we analyze the whole process which could yield the signal timing method.In order to make an optimal use of time and space resources,improvement in lane canalization at intersections,optimization in signal timing is put forward.The paper applies the traffic simulation software-VISSIM to simulate the whole process,compares the optimized test with the practical survey,which obtains a good effect.
