The invention discloses a cooperative control method for a main line and a ramp in an expressway interleaving area. The cooperative control method comprises the following steps: acquiring traffic flow information and vehicle information of the main line and the ramp in the expressway interleaving area; predicting information of a road section without the detection equipment to complement the traffic flow model; judging whether a control strategy needs to be developed; outputting a ramp control strategy according to the calculation module; judging whether the afflux ramp reaches a queuing threshold value or not; and outputting a main line and ramp cooperative control strategy according to the calculation module. The method focuses on the problem of bottleneck traffic in the expressway interlacing area, main line control and ramp control are coordinated, the traffic capacity of the whole interlacing area is maximized, crux points of the interlacing area are differentiated and relieved, the efficiency of an expressway network connection intelligent traffic system is improved, and a method adopting an interlacing area control strategy is perfected.

    本发明公开了一种高速公路交织区主线与匝道协同控制方法,包括获取高速公路交织区域主线与匝道的交通流信息与车辆信息;预测未部署检测设备路段的信息以补全交通流模型;判断是否需要开展控制策略;根据计算模块输出匝道控制策略;判断汇入匝道是否到达排队阈值;根据计算模块输出主线与匝道协同控制策略。本发明着眼于高速公路交织区发生瓶颈交通的问题,将主线控制与匝道控制相协同,最大化整体交织区的通行能力,将交织区的症结点分化舒缓,有助于提高高速公路网联智能交通系统的效率并完善采取交织区控制策略的方法。
