摘　　要：基于最大绿波带的设计理念,利用干道协调控制中的时距分析方法,建立了一种改进的进口单独放行方式下干道双向绿波协调控制数解法。这一算法能够解决干道中存在双周期、三周期交叉口的问题,使得多周期交叉口存在下依然可以进行双向绿波协调控制,扩大了进口单独放行方式下干道双向绿波协调控制数解法的适用范围。最后给出了算例分析,运用微观仿真软件Vissim对通过算法得到的控制方案进行模拟,仿真结果表明这一方法能够显著的改善延误和停车次数。Based on the design principle of maximum green wave bandwidth and on the time-space analysis, an improved algebraic method of bidirectional green wave was established, which can be used for arterial road coordinated control in the signal design mode of one-phase-one-approach. The problem that an arterial road has a double cycle or triple cycle intersection can be solved with this method. This improved algebraic method has enlarged the scope of application with the algebraic method of bidirectional green wave for arterial road coordinated control under the signal design mode of one- phase-one-approach. An example was analyzed. The obtained control program was simulated by using VISSIM microcosmic simulation software. The results show that the method can significantly improve delays and stops.
