单个交叉口多相位交通信号的智能控制
Multi-phase Traffic Signal Intelligent Control for Isolated Intersections
摘要：本文针对交叉口交通流运行的高度复杂性和随机性,提出一种多相位模糊控制方案。即根据交警在指挥交通时的思想，在对某相位放行是否需要给此相位绿灯延时，取决于此相位排队长度和下一相位排队长度的综合比较。也就是用当前相和后继相的车辆等待长度决定信号配时。本文借助MATLAB模糊逻辑工具箱设计二维模糊控制器并在SIMULINK环境下建立模型进行仿真，以车流的平均延误及车流通行能力为评价指标。仿真结果表明，模糊控制的车流延误较定时控制下降20％左右,车流通行能力提高10%左右。
bstract: As the high complexity and random of the traffic flow, a multi-phase fuzzy control solution is proposed in the thesis. Namely, according to the strategy of the traffic policy, when to turn to certain phase depends on the combined comparison of the length of the queue between this phase and the next phase. That is, the distributed time depends on the length of vehicle queue in present and the next phase at controlled junction. By means of fuzzy logic toolbox in MATLAB, two-dimensional fuzzy controller is designed and simulated under the circumstance of SIMULINK. The simulation results are evaluated by the standard, i.e., the average delay of the flow and traffic capacity. The results illustrate that the mean delay time of the fuzzy control decreases by about 20% and the traffic capacity increases 10% compared with that of the fixed-time control.
