摘　　要：货物运输模型的发展尚处于初级阶段,还未得到应有的重视.本文分析了各模型的基本过程、技术路线、优势及劣势,从现有文献中综合概括出全面统一的评价标准,并对不同模型性能进行评价.结果表明,相较其它模型,基于出行链的模型可更好地模拟实际情况.然而,每种模型都仅在某些方面优于其它模型,没有最优的货物运输交通模型.研究人员应基于问题实质和范畴等指标,而不是仅仅出于粗略的性能评价和个人偏好.The freight transportation model is comparatively underdeveloped and had not been paid much attention to for decades. This study provides a synopsis of existing models at the urban and metropolitan levels, their major procedures, techniques, weaknesses and strengths. Based on consistent and comprehensive criteria synthesized from existing literature, this study also assesses the performances of different models. The assessment indicates that the tour-based model outperforms other ones. Each model, as expected, only outperforms others in some aspects. That is, there is no perfect freight model. Freight modelers should adopt a context-sensitive and problem-specific attitude when choosing their respective models. Specifically, choosing models based on the nature and scope of the problem at hand rather than on general performance assessment results or related personal impression or preference.
