| 摘 要： | 时间参数和相位结构是单点自适应控制策略的重要参数。介绍了最佳绿灯时间、最小绿灯时间、最大绿灯时间、单位绿灯延长时间、绿灯间隔时间、黄灯时间等的计算和取值方法。参考NEMA标准的双环相位结构，分析了单点自适应控制策略的备选相位切换方案，提出“三阶段”相位切换过程，能灵活地实现相位组合和相位切换，降低相位切换决策方法的复杂程度。

| Abstract: | Time parameters and phase scheme are important parameters for adaptive control strategies at isolated signalized intersections. This paper introduces the methods to determine optimal green time, minimum green time, maximum green time, unit extension time, inter-green time, and amber time. Referring to the standard NEMA dual ring phase scheme, it analyzes the candidate phase transition and presented the concept of 3-stage phase transition process, which can generate the phase combination and phase transition with high flexibility and is able to reduce the complexity of decision making process. |
