单个交叉口两级模糊控制及仿真研究

伴随着我国国民经济的高速发展和城市化进程的加快,城市交通拥堵问题日趋严重,交叉口作为城市交通网络的重要组成部分,解决城市道路交叉口问题是解决城市交通的关键,对其研究有着极其重要的意义。在对现有国内外学者对交叉口信号模糊控制研究的基础之上,对单个交叉口的模糊控制进行系统的分析阐述,提出了一种新型的交叉口两级模糊控制方法。对于模糊控制中复杂的逻辑推理和计算问题采用MATLAB进行编程计算。最后,运用MATLAB进行模糊控制器动态仿真,结果表明模糊控制效果更好。

Two-stage Fuzzy Control and Simulation at Single Intersection

With the rapid development of China ’s national economy and the acceleration of urbanization process,urban traffic congestion is growing.Intersection is an important part of the urban traffic network,if the network problems have a bad handled,traffic congestion will be especially prominent.To solve the problem of urban traffic intersection is the key of solving urban traffic,and it has great significance.Based on the existing domestic and foreign scholars on the intersection signal fuzzy control,after described single intersection of a systematic analysis of fuzzy control,a novel method of the intersection of two-stage fuzzy control is presentel.The MATLAB programming to reason and calculate is used.Finally,the fuzzy controller by MATLAB is simulated.And the results show that fuzzy control is better.
