摘　　要：为提升城市快速路的交通运行效率,缓解快速路"上不去"现象,结合新一代感知技术,基于经典的ALINEA控制方法,将快速路主线、入口匝道及衔接交叉口作为协同控制对象。针对协同控制范围内不同的交通流运行状态,提出了4种协同控制策略,构建入口匝道信号控制算法及衔接交叉口信号优化算法。利用VISSIM软件进行交通仿真验证,结果表明,自适应协同控制方法在早高峰时段交通流运行特征下,主线上游平均车速提高了20.7%,入口匝道排队长度与协调区车均延误分别降低了26.7%和16.9%。研究成果为快速路实施入口匝道节点管控的工程应用提供借鉴。In order to improve efficiency of urban expressway traffic,alleviate expressway "unavailable" phenomenon,the main line of expressways,on-ramp and intersections are taken as the coordinated control objects based on the ALINEA control method combined with the new generation of perception technology.Based on different traffic flow running states,four cooperative control strategies are proposed,and the on-ramp signal control algorithm and intersection signal optimization algorithm are constructed.Using VISSIM for traffic simulation verification,the results show that the average speed upstream of main line,the queuing length of on-ramp and the vehicle delay in coordination area are optimized by 20.7%,26.7% and 16.9% respectively under the traffic flow characteristics in morning peak hours.The research results provide reference for the engineering application of on-ramp control in expressway.
