提出一种模糊逻辑方法控制高峰期间进入高速公路的车辆数目。分析了模糊逻辑控制器的基本结构,阐述了模糊控制算法,给出了隶属度函数,根据高速公路上游、下游及入口匝道上安装的传感器检测到的流量、速度、占有率、匝道排队长度等信息,设计了入口匝道模糊逻辑控制器,并用计算机对控制器进行了仿真,仿真结果表明该方法切实可行、具有实用价值,它能避免高速公路主线交通拥挤和堵塞,提高主线的通行能力,实现车辆在高速公路上高效、安全的运行。
A fuzzy logic approach is proposed to control the number of vehicles entering the freeway during peak periods. The basic structure of the fuzzy logic controller is analyzed. The fuzzy control algorithm is expounded. The membership function is given. Based on the flow rate, speed, occupancy rate, the length of the ramp queue and so on, which are detected by the sensors installed on the upstream, downstream and inlet ramps of the expressway Information, designed the entrance ramp fuzzy logic controller, and the computer simulation of the controller, the simulation results show that the method is practical and practical, it can avoid traffic congestion and congestion on the main line of the highway to improve the capacity of the main line of access to achieve Vehicles run efficiently and safely on the highway.
