摘　　要：为提升多车道高速公路主线合流区通行效率,由于主线合流区各车道交通特征差异,针对多条匝道相互合流再一同汇入主线的情况,分析了主线合流区流量均衡状态、各车道饱和状态和匝道流量对通行效率的影响,提出了多车道高速公路车道分配与入口多匝道协同控制模型,主要通过主线车道控制引导上游主线车辆提前选择合适车道行驶,同时采用入口多匝道控制协调匝道合流区各汇入匝道车辆的驶入,实现主线和匝道的通行效率最大化提升。仿真验证及工程应用结果表明:通过主线车道控制引导上游主线车辆尽量选择内侧车道行驶,尽管会增加内侧车道行驶车辆的车均延误,但明显降低了主线和匝道的整体车均延误,说明主线车道控制与入口多匝道控制相结合对合流区通行效率提升优势明显,且主线合流区各车道流量均衡有助于提升入口匝道汇入效率。To improve the traffic efficiency of the mainline merge area of the multi-lane expressway,the influence of traffic flow equilibrium state,saturation state of each lane and ramp traffic flow on traffic efficiency was analyzed in the situation that multiple ramps merge into the main line,considering the differences in traffic characteristics of each lane in the mainline merge area.Lane assignment of a multilane expressway and entrance multi ramp cooperative control strategy is proposed for the situation where the mainline lane control guides the upstream mainline vehicles to choose the appropriate lane in advance,while the entrance multiple ramp control coordinates the vehicles of each merging ramp in the ramp merging area to maximize the traffic efficiency of the mainline and ramps.The results show that the mainline lane control guides the upstream mainline vehicles to choose the inner lane as much as possible,which increases the average delay of the vehicles driving in the inner lane but significantly reduces the overall average delay of the mainline and ramps,indicating that the combination of mainline lane control and entrance multiple ramp control has obvious advantages to improve the traffic efficiency of the merging area,and the balanced flow of each lane in the mainline merging area helps to improve the entrance ramp convergence efficiency.The mainline merge area has a balanced flow of lanes,which helps to improve the efficiency of the entrance ramps.
