一种基于通行需求度的单交叉口模糊控制算法

针对城市交通拥挤问题，提出一种根据通行需求度确定通行相位和通行时间的、可变相序的单交叉口模糊控制算法。仿真结果表明，在不同交叉口结构形式、不同相位构成和不同车流量组合的各种情况下，该方法均表现出良好的控制效果，是解决城市交通拥挤问题的有效途径。

A Pass Through Need Degree-based Isolated Intersection Fuzzy Control Algorithm

Aimed at the congestion problem of city traffic, a phase sequence-changeable isolated intersection fuzzy control (algorithm) is proposed based on the pass through need degree by which the next green phase and its green time length are (determined.) The simulation results indicate that in any configuration of different intersection structure, phase composing, and flow rate combination, the algorithm always shows a better control performance, it is an effective approach for solving the congestion problem of urban traffic.
