摘要
针对高速公路交通流特征复杂多变,并受到天气、道路状况和车辆类型等多种因素影响的问题,设计了一种新的高速公路实时交通流模糊逻辑优化控制系统,包括硬件和软件两部分;在硬件方面,设计了车流控制模块、无线传输车载终端、实时交通流逻辑调度模块和模糊控制器模块,并确定了它们之间的实时连接关系;在软件方面,求解了交通流逻辑控制条件,联合了高速公路实时通行相位条件,调节了模糊控制器,并根据高速公路交通路网模型推导了交通流优化控制条件的求解表达式;实验结果表明,该系统可以解决逻辑协调错误的问题,并有效控制高速公路车流量.
Abstract
To address the complex and variable characteristics of highway traffic flow on highways,it is influenced by various fac-tors such as weather,road conditions,and vehicle types,a new real-time traffic flow fuzzy logic optimization control system on high-ways is designed.The system is composed of hardware and software components.The hardware of the system includes the vehicle flow control module,wireless transmission vehicle terminal,real-time traffic flow logic scheduling module,and fuzzy controller mod-ule,and the real-time connection relationships between modules is determined.In the software of the system,it solves the traffic flow logic control conditions,combines with the real-time traffic phase conditions of the expressway,adjusts the fuzzy controller,and de-rives the expression for the traffic flow optimization control conditions based on the expressway traffic network model.The experi-mental results show that the system can solve the problem of logical coordination errors and effectively control the traffic flow on highways.
