摘　　要：基于快速路实测数据和微观仿真数据,从交通流基本图、交通流状态空间传播、匝道与主线流量关系和车道横向分布特征4个方面对比了匝道合流区与基本路段的交通流特征。结论表明:由于匝道车辆汇入的影响,匝道合流区与基本路段的交通流特征存在较大的差别,在城市快速路的规划、设计、管理和控制中都应该区别对待。Based on research data of expressway and micro simulation data,traffic flows characteristics of ramp merging area and basic road section were compared from the aspects of basic diagram of traffic flows,spatial transmission of traffic flows state,volume relationship between ramp and mainline and transverse distribution characteristics of different lane.The conclusion indicated that because of influence of importing vehicles,there were great distinctions of traffic flows characteristics between ramp merging area and basic road section.It should be considered differently in planning,design,management and control of urban expressway.
