摘　　要：为使城市交通运行更加通畅,设计城市干道双向绿波协调控制方案。根据理论知识和实际工程实施经验,提出不同交叉口间距及行程时间情况下设计双向绿波方案的方法和技巧,按照路口间距、周期特点,设计信号相序相位,将对称相位、单口放行相位和搭接相位等相位灵活组合运用,然后分配绿信比,找到双向绿波上行、下行绿波带宽最大化且较均衡的相位差。以曲靖市金宝路6个路口为例,设计双向绿波协调控制方案,并下载方案试运用。通过绿波下载前、后实地驾车实验对比发现,行车时间减少60%,停车次数减少49%,验证方案可行性。该方法在曲靖市很多干道信控路口实施应用,取得了较好的社会效益。Bidirectional green wave control can make urban traffic run more smoothly,based on the practical experience of engineering measures,methods and techniques for designing bidirectional green wave schemes at different intersection distances and travel times are proposed.According to the intersection distance and period,the signal phase,symmetrical phase,single-pass release phase,and overlap phase are bidirectional green wave control technology signed skillfully,in order to find the maximum and balanced phase difference for the up and down traffic.Finally,taking six intersections of Jinbao road in Qujing as an example,designed bidirectional green wave control scheme and downloaded it for trial use.Through driving experiments,it is found that the driving time is reduced by 60%,and the number of parking times is reduced by 49%,which verifies the feasibility of the scheme.Therefore,this method has been implemented at many signalized intersections in Qujing,and the social benefits are better.
