摘　　要：为提升城市快速路管控水平,缓解快速路拥堵,文章对城市快速路匝道信号控制的理论研究进行梳理,对天津市快速路进行了调查研究,报告了天津市快速路交通现状,针对实际情况对快速路环线的部分匝道口进行了交通信号控制系统整体优化设计,提出了一种基于增强学习的快速路交通信号自动控制方法,控制匝道开启和关闭,并通过管控前后交通状态数据验证了该控制系统的有效性。In order to improve the control level of urban expressway,and alleviate the congestion of expressway,this paper combs the theoretical research on ramp signal control of urban expressway,investigates and studies the expressway general situation in Tianjin,reports the traffic status of the expressway,and optimizes the overall design of traffic signal control system for some ramps of expressway ring road according to the actual situation.An automatic control method of expressway traffic signal based on reinforcement learning is proposed to control ramp opening and closing.The effectiveness of the control system is verified by the traffic state data before and after the control.

关 键 词：快速路 信号控制 增强学习 自动控制
