The invention relates to an expressway main line divided lane control and entrance ramp cooperative control method, and belongs to the field of intelligent traffic. The method comprises the steps that S1, a plurality of vehicle detectors are installed on a main line branch lane and an entrance ramp respectively, and the branch lane flow, the vehicle speed and the density of corresponding detection points are obtained; s2, constructing a main line divided lane management and control model: calculating a lane predicted flow rate ratio when a vehicle on each lane on a main line runs to a confluence area, then obtaining a traffic operation state grade of each lane on the main line of the confluence area by combining a traffic operation state grade division rule, and carrying out grade adjustment according to the condition of each lane; and S3, constructing an entrance ramp control model: calculating an entrance ramp adjustment rate in the current control period, and comparing the entrance ramp adjustment rate with the ramp traffic flow for judgment to obtain the green light keeping duration of the ramp control signal lamp. The traffic flow of the ramp converging into the main line can be increased, the traffic capacity of the converging area is improved, and the lane changing frequency of vehicles in the converging area is reduced.

    本发明涉及一种快速路主线分车道管控与入口匝道协同控制方法,属于智能交通领域。该方法包括:S1:分别在主线分车道和入口匝道上安装多个车辆检测器,获取相应检测点的分车道流量、车速和密度;S2:构建主线分车道管控模型:计算出主线上各车道车辆行驶至合流区的车道预计流率比,然后结合交通运行状态等级划分规则得到合流区主线上各车道交通运行状态等级,并根据各车道情况进行等级调整;S3:构建入口匝道控制模型:计算当前控制周期入口匝道调节率,并与匝道交通流量进行比较判断,得到匝道控制信号灯保持绿灯时长。本发明能增大匝道汇入主线交通流量,提升合流区通行能力,降低合流区车辆变道次数。
