摘　　要：城市快速路与其平行的地面主干路存在紧密联系,形成天然的交通走廊。对于城市快速路交通走廊的拥堵问题,应采取协同控制,充分考虑其中的高度关联。本文综述了城市快速路交通走廊控制的发展历程,并展望了未来研究方向。传统的控制理论多为集计层面的交通流控制,状态估计由模型推导得到,并通过滚动时间窗更新。然而,一些交通现象难以精准刻画,且难以大范围应用。随着信息技术的发展,全覆盖以及实时的交通监测成为可能,控制方法的协同性、实时性、精准性不断提高。未来随着智能网联车辆和自动驾驶车辆的逐渐普及,原先由人类驾驶车辆组成的交通流将转变为新型混合交通流,控制手段将广泛作用于个体车辆,实现高度协同的车辆控制,且交通管理控制将与出行服务高度整合。新型混合交通流模式下的城市快速路交通走廊控制将是未来研究的重点。同时,用户最优与系统最优的最佳组合也是需要关注的问题。Urban expressway and its parallel surface arterial are closely related, and they compose a traffic corridor. For traffic congestion in the corridor, it is necessary to take integrated control and to consider the high correlation within the corridor.Thispaperreviewsthedevelopmentofurbanexpressway-arterial corridor control and discusses the prospects for future studies.Traditionally, traffic flow is controlled at an aggregate level. Traffic state estimation is derived by traffic models and updated with rolling windows. However, some traffic phenomena could not be accurately described, and large-scale applications are difficult. With the development of information technology,full coverage and real-time traffic monitoring become possible. The synergy,timeliness,and accuracy of control methods are all improved. In the future, with the gradual popularity of connected and autonomous vehicles,traffic flow,which is composed of human-driven vehicles,will become mixed traffic flow. Control measures will be widely implemented on individual vehicles to achieve high coordination among vehicles. Also,traffic management and control will be highly integrated with travel service. Future studies will focus on control theories towards this newmixedtrafficflow.Meanwhile,the optimum combination of user optimization and system optimization is also a critical issue.
