摘要
在城市交叉口信号控制中,相位相序的设计与通过交叉口的车流轨迹有着非常密切的关系,在不改变相位组合的情况下,合理的相位相序可使交叉口通行效率大幅度提升。本文通过对交叉口车流轨迹冲突点进行分析,在保证车辆安全通过的情况下,以绿信比最大为目标,建立相位相序优化模型。此外,文中以广州市某交叉口为例进行相序优化,使交叉口效率提高13.4%。
Among Intersection signal control in urban areas,the Phasing-Sequence design has a very close relationship with the traffic flow path through the intersection. Without changing the phase combination of circumstances,a reasonable Phasing-Sequence can greatly enhance the efficiency of intersections. By analyzing the conflict point of traffic tracks in intersection and ensuring the safe passage of vehicles to pursuit the maximum of green signal ratio,this paper establishes a Phasing-Sequence optimization mod- el. Taking the intersection of Guangzhou as an example,the Phasing-Sequence optimization resulted in an upgrade of efficiency of 13.4 %.
