摘要
针对日益严重的交通拥堵问题设计出一种新型两级模糊控制方案来对四相位三车道单交叉口的交通信号灯进行实时智能控制。该新方案沿用了当前各种交通信号灯控制方案的优点,同时针对其不足之处进行了弥补与完善,是一种同时具有自适应控制、分级模糊控制、相位繁忙优先和准确显时等优势的控制方案,更适用于实际的交通情况。对新型模糊控制方案进行了仿真研究,仿真结果表明该方案明显优于传统控制方案。最后还对该新方案进行了动态模拟演示,使其更具可观性和真实性,更易于运用到交通现场。
A new type of two stage fuzzy controller designed to perform the real time intelligent control of traffic signals on four-phase single intersection of three lanes to slove the problem of the increasingly serious traffic congestion. This new program keeps up the advantages of each traffic signal control scheme adopted at present. At the same time, it makes up the shortcomings and perfects these traditional control schemes. It is a self-adaptive, hierarchical fuzzy, priority option and accu- rate phase control program, and as a result it is more suitable for the actual traffic conditions. In addition, this new type of fuzzy control scheme was simulated. The simulation result shows that the scheme is clearly superior to the traditional control schemes. Finally, the dynamic simulation illustration of the new program is offered in this paper, which makes it more impressively, authentically and easily apply to the traffic scene.
