新型模糊控制算法在交叉口信号控制中的应用

作为智能控制的分支,模糊算法已越来越多地应用于交叉口信号控制,成为交叉口信号控制的新热点。文中通过提出路段车辆数这一新概念,提出了一种新型的孤立交叉口信号控制的模糊算法,实现了孤立交叉口信号控制的优化,并在此基础上进行了系统仿真。通过与传统定时控制方法进行分析对比,论证了这种新型模糊控制算法在车辆延误时间和排队长度方面有较大的改善,具有实用性和可靠性。

A New Fuzzy Control Method for Isolated Intersection Traffic Management

Intelligent control is an inevitable trend of urban traffic management and fuzzy control is one of its effective methods. In this article an attempt is made to apply fuzzy control to urban traffic system by proposing a new concept of link vehicle in designing the fuzzy controller. The effectiveness of this method was simulated on a single intersection. The experimental results show that the proposed fuzzy logic controller outperforms the existing controllers in terms of the average delay of vehicles as well as the queue length.
