摘要/Abstract

摘要： 针对高峰期间交叉口各进口道排队不均衡或溢出的现象，提出了一种基于视频排队长度管理的小步增减绿信比方法。首先，判断红灯结束时的排队状态及绿灯结束时的排队长度等级；然后，计算各个相位绿灯时间的增减量；最后，以均衡各进口道排队长度为目标，实现各相位绿灯时间与各进口道排队长度的动态平衡。实验结果表明，所提优化方法能有效地均衡各个进口道的排队长度，降低交叉口的通行延误和交通拥堵。当相位绿信比与排队长度不匹配时，该优化方法能快速进行绿信比调整，以适应排队长度的变化。

Abstract: Concerning the phenomenon that the queues in the entrance lanes of the intersections are imbalanced or overflowed during the peak hours, an incremental split selection method based on video queue length management was proposed. Firstly, the queueing state at the end of the red time and the queueing length level at the end of the green time were judged. Then， the increment or decrement of the green time of each phase was calculated. Finally, the dynamic balance between the green time of each phase and the queue length of each entrance lane was realized with the purpose of balancing the queue lengths of the entrance lanes. The experimental results show that, the proposed optimization method can effectively balance the queue lengths of the entrance lanes, reducing the traffic delay and traffic congestion at the intersection. When the split does not match the queue length, the optimization method can quickly adjust the split to adapt to the change of the queue length.

Key words: video, queue length, incremental split selection, traffic signal timing optimization, traffic signal control
