摘　　要：为了提高改扩建城市道路施工作业区的服务水平,基于实测数据对双向六车道城市道路施工作业区不同路面损害程度道路通行能力及交通流特性进行分析。对比不同路面损害程度断面平均速度、交通密度及速度连续性。结果表明:严重的路面损害情况大大降低了道路通行能力及交通流连续性,尤其是车道减少的城市道路改扩建路段。同时,车辆在经过某一路面损害路段时其车速呈现骤降趋势,影响道路交通安全。In order to improve the service level of the urban Roadworks construction operation area for reconstruction and expansion,based on the measured data,the traffic capacity and traffic flow characteristics of the two-way six lane urban Roadworks construction operation area with different pavement damage degrees are analyzed.Comparative analysis was conducted on the average speed,traffic density,and speed continuity of sections with different degrees of road damage.The results indicate that severe road surface damage significantly reduces road capacity and traffic flow continuity,especially in urban road reconstruction and expansion sections with reduced lanes.

关 键 词：改扩建施工作业区 路面破损 通行能力 速度连续性
