摘　　要：汽车性能的提升催生了高速公路提速的迫切需求,八车道高速公路的建设为超高速汽车行驶提供了客观基础。现设计了行驶速度140 km/h的三种宽度的八车道高速公路客车专用车道,分别为3.50 m、3.60 m与3.75 m。基于驾驶模拟实验数据,从通行效率、运行速度与车道保持能力三个方面,分析不同车道宽度下车辆的运行特征。研究结果表明,双向八车道高速公路客车专用车道的车道宽度采用3.50 m、3.60 m和3.75 m,均能满足车辆运行速度维持在140 km/h,通行效率与安全水平无显著差异。因此,三种车道宽度均能满足客车专用车道的要求。从节约用地的角度,推荐3.50 m的车道宽度。The improvement of vehicle performance inspired the urgent demand for rapid increase of expressway.The construction of eight lane expressway provided an objective basis for ultra-high speed vehicle driving.This paper designed three kinds of eight lane expressway passenger express lanes with driving speed of 140 km/h,which were 3.50 m,3.60 m and 3.75 m,respectively.Based on the driving simulation experimental data,the running characteristics of vehicles under different lane widths were analyzed from three aspects:traffic efficiency,running speed and lane holding capacity.The research results showed that the lane widths of passenger dedicated lanes of two-way-eight-lane expressway of 3.50 m,3.60 m and 3.75 m could meet the vehicle running speed of 140 km/h,and there was no significant difference in traffic efficiency and safety level.Therefore,the three lane widths could meet the requirements of passenger dedicated lanes.From the perspective of land conservation,a lane width of 3.50 m was recommended.
