摘　　要：为了改善可变限速控制在应用过程中带来的通行效率损失,采用自动巡航与可变限速协同控制来对高速公路车辆进行管控。基于智能驾驶员模型建立了自动巡航控制模型,结合可变限速控制形成了协同控制方法,采用美国NGSIM微观交通流数据对模型进行了标定,并进行了高速公路仿真实验。仿真结果表明:协同控制能在有效降低瓶颈路段上游车辆速度的同时,降低平均每辆车增加的通行时间比例,从而有效改善高速公路的通行效率。In order to improve the loss of traffic efficiency caused by the application of variable speed limit control,the integration of adaptive cruise control and variable speed limit control is analyzed to control the highway traffic.The cruise control model is developed from the intelligent driver model,and then it is integrated with the variable speed limit control method.The microscopic traffic data of the NGSIM in the USA are used to calibrate the models.Simulations of the highway traffic are carried out.Results show that the integrated control method reduces the average increasing rate of vehicles' travel time by successfully declining the speed of the vehicles in the upstream of the bottleneck,thus improving the traffic efficiency of the highway.The results of this study may provide valuable information for highway traffic management.
