Abstract: 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.
