The invention discloses an expressway long-distance downstream bottleneck road section entrance ramp control method, and belongs to the technical field of intelligent transportation. The method comprises the steps that multiple traffic flow detectors are arranged on an expressway at equal intervals, the traffic flow state is judged according to read traffic flow data of all road sections of the expressway, and the traffic flow data are output in real time; and for traffic flow characteristics in the scene, a fuzzy self-adaptive proportion-integration-differentiation control strategy is adopted, and the control strategy is composed of proportion-integration-differentiation control and fuzzy control. The method solves the problem that according to an existing entrance ramp control strategy,the problem about reduction of the control effect caused by time delay is difficult to eliminate, and the method has important significance in improving the traffic capacity of a long-distance downstream bottleneck and improving the overall running efficiency of the expressway.
本发明公开了一种针对高速公路长距离下游瓶颈路段入口匝道控制方法,属于智能交通技术领域。包括:在高速公路上等距离设置多个交通流检测器,根据读取的高速公路各路段交通流数据,判断交通流状态,实时输出交通流数据。针对该场景下的交通流特征,采用模糊自适应比例‑积分‑微分(PID)控制策略,该控制策略由比例‑积分‑微分(PID)控制和模糊控制组成。解决了现有入口匝道控制策略难以消除因为时间延迟带来的控制效果降低的问题,本发明对于提高长距离下游瓶颈的通行能力、提高高速公路整体运行效率具有重要的意义。
