摘要
在现有道路交通条件下,实现干道上信号协调控制能有效提高主干道的通行能力。分析了城市道路交叉口的平均延误时间、道路通行能力和信号配时的数学模型和计算方法。以某城市主干道为例,在对某条主干道11个主要信控交叉口进行了大量交通量调研的基础上,选取了有代表性的三个交叉口作为协调控制交叉口。根据该道路的几何结构特征,在调查实际数据的基础上,提出"分时段分方向、设置半周期时长"的干道信号协调控制方法,应用Synchro仿真软件建立基于原控制参数的干道信号协调控制系统;同时,在应用Synchro优化各个独立交叉口信号控制参数的基础上,建立了基于优化控制参数的信号协调控制系统。
In the existing road traffic conditions,the realization of trunk road signal coordination and control can effectively improve the capacity of the trunk road. Taking a city main road as an example,based on a large amount of traffic investigation on 11 major intersections of a main road,three representative intersections are chosen as the coordinated control intersection. According to the geometric structure of the road and the investigation of actual data,this paper proposes a coordinated control method of trunk signal based on sub-period direction and half cycle time,and applies the Synchro simulation software to build the main road signal coordination control system based on the original control parameters. At the same time,the signal coordination control system based on the optimal control parameters is established on the basis of the Synchro optimization signal control parameters of the individual intersections.
