摘　　要：基于相邻交叉口之间的交通流特性,考虑了边路车辆在下游交叉口处排队、驶离对相位差的影响,分析了6种干线车流在下游交叉口处的到达、排队、驶离情况,分别确定了与各种情况相对应的相位差范围,并进行干线车辆延误分析,构建了干线车辆延误最小的相位差优化模型。选取南昌市赣江北大道的5个相邻交叉口进行模型验证,明确了交叉口间相位差与干线车辆延误的定量关系,确定了干线系统延误最小时的相位差。结果表明:优化模型可明显降低干线车辆延误,干线系统总车均延误减少了89.136%,可为后续研究边路车辆对干线信号协调的影响提供参考。Based on the characteristics of traffic flow between adjacent intersections,this paper first considers the influence of queuing and departure of side vehicles on the offset and analyzes the arrival,queuing and departure of six kinds of arterial traffic flow at the downstream intersection. Then,the range of offset corresponding to each situation is determined respectively. Third,the delay analysis of arterial vehicles is carried out. Finally,an optimization model of offset with the minimum delay of arterial vehicles is established. Five adjacent intersections of Ganjiang North Avenue in Nanchang city are selected as examples to verify the proposed model. The quantitative relationship between offset of intersections and the delay of arterial vehicles is clarified,and the minimum delay of arterial system as the aim of offset is determined. The results show that the optimization model can significantly reduce the delay of arterial vehicles,and the total delay of arterial vehicles is reduced by 89.136%. The optimization model proposed can be used as a reference for the follow-up study of the influence of vehicles on side road on the arterial signal coordination.
