摘　　要：针对进出城市的高速公路与关联城市快速路(简称结合部区域)交通拥堵日益恶化的现象,以结合部区域为研究对象,从结合部区域的匝道控制影响因素分析入手,建立了一种适用于结合部区域的单点入口控制模型和多入口匝道协调控制模型,以京津塘高速公路与北京市三环、四环的结合部区域为例,以实地调研及交通流检测数据为基础,通过仿真验证其有效性,为匝道协调控制实际应用提供理论方法.For the worsening phenomenon of traffic congestion of freeway and related urban expressway（Abbreviations：junction）where into and out of the city,and starting with analysis of ramp metering influence factors,this paper chooses junction area as the research object,and then establishes a single on-ramp and multi-on-ramp coordinated metering model designed for junction.Finally,take junction of Jing-Jin-Tang freeway and related the third and fourth ring expressway as an example based on investigating and monitoring traffic flow data.The simulation results show its effectiveness,providing theoretical reference for the practical application on coordinated ramp metering.
