基于模糊逻辑的路口交通信号控制

城市交通控制(UTC)是智能交通系统中非常重要的组成部分。在一些复杂的交通情况下,使用传统的控制方法进行交通信号控制的效果并不好。由于模糊逻辑能够较好地描述复杂系统的定性模型,因此它非常适合对路口交通信号灯进行控制。该文给出了一种采用模糊逻辑进行路口信号灯控制的方法。通过从路口检测器获取车辆信息,模糊规则对信号灯进行优化控制。通过仿真模拟,给出了实验结果。

Study on Fuzzy Signal Control

Urban traffic control is a very important part in intelligent traffic system. There are many conventional methods for traffic signal control, but they sometimes fail to deal efficiently with complex, time-varying traffic condition. Because fuzzy logic is adequate for the qualitative modeling of complex systems, it is very applicable for signal control.In this paper, an intersection signal control method using fuzzy logic is given. It gets information form traffic detectors. And using this information, the fuzzy rule gives optimal signals. The proposed method is compared with the traditional timing control method. The simulation results show good performances in the case of heavy traffic conditions.
