基于半感应绿波控制策略,分析协调相位与感应相位运行时间关系.针对相位优化产生的感应余量和协调相位弹性调节量等时间结余,研究了相位时间二次分配问题,建立了二次时间分配算法.结合实际交通调查数据仿真分析二次分配算法对绿波交通整体运行控制的合理性,结果表明二次分配算法可有效解决线协调控制存在的绿波损失问题.

Based on the semi-sensitive Green Wave control strategy,the running time relationships between coordination phase and induction phase are analyzed.The secondary distribution of phase time is studied in accordance with time margins produced by sensing margin and flexible adjusting volume of coordination phase,and the secondary distribution algorithm of time proposed.Combined with the actual investigation,the rationality of secondary distribution algorithm to control the overall operation of Green Wave Traffic is simulated and analyzed.The result shows that the secondary time distribution algorithm is effective to solve the green wave loss caused by the line coordination control.
