为了进一步分析相序对绿波带宽的影响,以进口对称放行的方式为研究对象并在MAXBAND模型中考虑左转早断、滞后和早断-滞后相序对带宽求解的影响。在交叉口数分别为2到5个的情况下,通过计算机编程实现对100个案例求解最大带宽,研究结果表明:改进的MAXBAND模型能求解左转情况下的最大带宽;左转早断-滞后相序更有利于获得最大带宽;当驶入驶离方向的左转绿信比一致时,使用早断与滞后相序获得的最大带宽相同;当绿信比不一致时,早断相序明显优于滞后相序;协调控制干道的相序保持一致性更有利于获得更大带宽。
In order to further analyze the effect of phase sequence on the green-wave bandwidth, we consider the mode of import symmetry release and consider the influence of left-turn pre-break, lag and early break-lag phase sequence on bandwidth solution in MAXBAND model. When the number of intersections is 2 to 5, the maximum bandwidth of 100 cases is solved by computer programming. The results show that the improved MAXBAND model can solve the maximum bandwidth in the case of left turn, and the left turn early break-lag phase When the left-turn green signal-to-signal ratio is the same, the maximum bandwidth obtained by using the early break and the lag phase sequence is the same. When the green signal-to-noise ratio is inconsistent, the early-break phase sequence is obviously better than Lagging phase sequence; coordinating the phase sequence control trunk more conducive to getting more bandwidth.
