摘　　要：针对十车道高速公路复杂行车环境下的车道功能划分问题,以广东省某高速公路改扩建工程为例,基于VISSIM仿真技术,通过熵值法构建车道功能划分方案评价模型,对比分析客货混行、内外幅分隔2+3、内外幅分隔3+2三种车道功能划分方案,最终评分分别为0.405、0.713和0.654。通过研究,明确了内外幅车道数分配方式对实际交通运行效率的影响,推荐依托工程采用内外幅分隔2+3车道功能划分方案。研究可为类似大规模十车道改扩建工程车道功能划分提供借鉴参考。In order to solve the problem of lane function division in the complex driving environment of the ten-lane expressway,taking the reconstruction and expansion project of an expressway in Guangdong province as the example,based on the VISSIM simulation technology,the evaluation model of the lane function division scheme is constructed by the entropy method,and three kinds of schemes for the lane function division,namely mixed passenger and freight traffic,internal and external width separation 2+3,and internal and external width separation 3+2 are compared and analyzed,and the final scores are 0.405,0.713 and 0.654 respectively.Through the research,the influence of the number of internal and external lane distribution on the actual traffic operation efficiency is clarified,and it is recommended to adopt the lane function division scheme for internal and external width separation 2+3 based on the project.The research can provide reference for the lane function division in similar large-scale ten-lane reconstruction and expansion projects.
