摘　　要：为研究不同车型在不同车道的运行速度差异,讨论不同设计速度下各车道的运行速度分布特点和规律,并提出不同车道运行速度推荐值,以应用于其他相关几何指标选取和验算。通过调查我国多车道高速公路的交通管理方式,基于包茂高速、西安绕城高速和连霍高速公路的实测不同车道车辆运行速度调查数据,绘制了每条车道的运行速度分布图、正态分布曲线和累计分布曲线,分析得到了多车道高速公路不同车道的运行速度特点和分布规律,并提出了不同设计速度下各车道的运行速度推荐值。结果表明:高速公路第1车道的运行速度大于等于设计速度,剩余车道的运行速度大于等于该车道的限制速度,但低于设计速度,说明车道限速偏低;运行速度由内侧车道向外侧车道呈递减趋势,内侧小客车专用车道运行最高,外侧车辆混行车道运行速度最低;按车型进行车道管理是一种有效的控制措施,对保证内侧小客车运行速度具有积极作用,但外侧车道车辆混行对行驶速度稳定存在负面影响,车辆行驶速度并不稳定;多车道高速公路不同车道的运行速度差异较大,计算道路几何指标时车辆速度直接采用设计速度的85%并不合适,应针对相应的多车道高速公路实际运行状况展开调查,以得到合适的运行速度取值;针对调查路段,统计得到了3车道和4车道高速公路不同车道运行速度推荐值,为其他指标的计算提供依据。In order to study the differences of operating speeds of different vehicles in different lanes, the characteristics and rules of operating speed distribution in each lane under different design speeds are discussed, and the recommended values of operating speeds in different lanes are proposed to be applied to other related geometric indicator selection and verification. By investigating the traffic management modes of multi-lane expressways in China, based on the survey data of measured vehicle running speeds in different lanes of Baotou-Maoming expressway, Xi’an ring expressway and Lianyungang-Horgos expressway, the running speed distribution diagram, normal distribution curve and cumulative distribution curve of each lane are drawn. The running speed characteristics and distribution rules of different lanes of multi-lane expressways are analyzed, and the recommended operating speeds in each lane under different design speeds are proposed. The result shows that(1) the running speed in the first lane of expressway is greater than or equal to the design speed, while the running speed in the remaining lane is greater than or equal to the restricted speed of the lane, but lower than the design speed, indicating that the lane speed limit is low.(2) The running speed decreases from the inner lane to the outer lane, with the highest running speed in the inner minibus lane and the lowest running speed in the outer mixed vehicle lane.(3) The lane management by vehicle type is an effective control measure, it has positive effect on ensuring the running speed of the inner passenger car, but the mixing of vehicles in the outer lane has negative effect on the stability of driving speed, and the driving speeds of the vehicles are not stable.(4) The operating speeds in different lanes of multi-lane expressway are quite different. It is not appropriate for the vehicle speed to directly adopt 85% of the design speed when calculating road geometric indicators. Investigations should be conducted on the actual operating conditio
