摘　　要：为提高干线协调信号控制的双向绿波带带宽,提出一种基于相位相序调整的绿波带带宽的设置方法。分析当两两交叉口的绿波带中心线交点水平之间的距离之差与理想交叉口的间距的余数之和为最小时,交叉口对应的相位相序可得到理想的绿波带带宽。结合时间−距离图,提出提高双向绿波控制中绿波带带宽的相位相序调整方法,并给出了具体步骤。以某一干道连续7个交叉口为例,对相位相序调整前、后的绿波控制结果进行了对比分析。研究结果表明:采用相位相序调整的绿波设计方法,能够有效提高双向绿波带的带宽;经VISSIM仿真试验验证,实施相位相序调整的绿波设计方法,可使上、下行方向车辆的平均行程时间、延误及停车次数均有不同程度的降低。In order to improve the bandwidth of bidirectional Green-band in trunk coordinated signal control,a method of setting Green-band bandwidth based on phase sequence adjustment is proposed.It is analyzed that the bandwidth of bidirectional green wave band corresponding to the phase sequence of intersections is the largest when the difference between the horizontal distance between the green wave band centerline intersections of two intersections and the sum of the remainder of the spacing between ideal intersections is the smallest.Based on the time-distance diagram,a phase sequence adjustment method for improving the bandwidth of green band in bidirectional green wave control is proposed,and the specific implementation steps are given.Taking seven consecutive intersections of a main road as an example,the green wave control results before and after phase sequence adjustment are compared and analyzed.The research results show that the green wave design method of phase sequence adjustment can effectively improve the bandwidth of bidirectional green wave band,and through the VISSIM simulation test,the average travel time,delay and parking times of vehicles in the up and down direction of the green wave design method of phase sequence adjustment are reduced to varying degrees.
