摘　　要：为增加高速公路主通道扩容方式选择的合理性和科学性,遵循综合性、直观性和可测性等3个基本原则,筛选高速公路主通道扩容方式的影响因素,从交通运行、出行效益和建设成本3个方面,建立评价指标体系;以VISUM交通仿真平台为基础,建立高速公路仿真模型;利用线性加权法进行综合评估,结果表明:评价指标体系能够较好地对高速公路主通道扩容方式进行评估。In order to select the highway main channel expansion mode more reasonably and scientifically,the influence factors are screened based on the three basic principles of comprehensiveness,intuitiveness and measurability.Then the evaluation index system is established in consideration of traffic,travel efficiency and construction cost three aspects.Based on the VISUM traffic simulation platform,the highway simulation model is set up.Linear weighting method is used to make a comprehensive evaluation.The results show that the evaluation index system can well evaluate the expansion mode of highway main channel.
