The invention relates to a control method for improving the traffic capacity of a bottleneck road section in an expressway tunnel, and belongs to the technical field of intelligent traffic control. The method comprises the steps of perceiving and recognizing a road bottleneck in a highway tunnel, dividing a road section control area and numbering lanes, numbering CAC and CHV of each lane in a control area, feeding back traffic flow information at the road bottleneck to each control area, and performing projection lane pre-changing for reducing traffic flow of the lanes in a projection adjustment area. The traffic flow is controlled to change lanes to the preset position in the actual lane changing area, the traffic flow cruising speed and the distance are adjusted to the ideal range in the following cruising area, and the expected speed and the distance are associated with the traffic flow information. According to the invention, a new way is provided for improving the traffic efficiency and the safety of the highway tunnel scene according to the traffic flow characteristics of the highway tunnel scene.
本发明涉及一种提升高速公路隧道内部瓶颈路段通行能力的控制方法,属于智能交通控制技术领域。该方法包括:感知识别高速公路隧道内部道路瓶颈,划分路段控制区域并对车道进行编号,对控制区各车道CAC和CHV进行编号,将道路瓶颈处车流流量信息反馈给各控制区,在投影调节区进行缩减车道车流的投影预换道,在实际换道区控制车流换道至预定位置,在跟驰巡航区调节车流巡航速度和间距至理想范围,其中期望速度和间距与车流流量信息相关联。本发明针对高速公路隧道场景车流特点,为改善其通行效率和安全性问题提供了新途径。
