摘　　要：对城市干线上一批相邻的交通信号进行协调控制,可减少干线上车辆的延误和停车次数。通过对城市干线常态与过饱和状态下的交通流状况分析,建立了对干线实施线控系统相位差优化调节的数学模型。该模型反应了沿干线行驶车辆在干线各交叉口延误情况的内在机理,是一种减少干线车辆延误的有效方法,对改善城市交通拥挤状况,提高干线道路服务能力具有积极的现实意义。Coordinated control of the neighboring traffic signals in the urban arterial road can reduce the vehicle delay and stop. The paper discussed the traffic situation of an urban arterial road under the normal state and over saturation state, a mathematic model of offset optimization separately in the two states was built up. The model describes the traffic delay mechanism of traveling vehicles in the arterial road, which is an effective method of reducing vehicle delay and is significance to improve the traffic congestion and to raise the service level of the arterial road.
