摘要
在城市交通控制中,交通路口各个方向的交通流分布不均匀,车流到达随机性大,非机动车与行人对交通路口信号控制有影响.针对此特点,利用多级模糊控制理论,提出了以车道组流率比为基准的混合交通路口变相位、变相序、变周期的动态多级模糊控制算法.最后用VC++语言进行了编程仿真,结果表明,与传统四相位信号控制相比,该控制算法效果较好.
In urban traffic control, the traffic volume of different direction at traffic intersection is imbalance,the arrival of vehicles is stochastic,and the non-vehicles and passerby interfere with the traffic intersection signal control. According to the characteristic, using the theory of multilevel fuzzy control, the dynamic multilevel fuzzy control algorithm with changeable phases, phase sequence and changeable periods that based on the flow rate of lanes is present. Finally authors simulate using the VC＋ ＋ language. The result shows that the algorithm of the control is better than the conventional four-phase signal control.
