城市货运交通模型构建方法研究——以广东省、深圳市和武汉市为例

Research on the Urban Freight Transport Model:Case Studies of Guangdong,Shenzhen and Wuhan

该文旨在探讨不同视角下的货运交通模型构建策略以及在货运交通需求量化分析方面的得失。介绍了货运交通模型研究的现状以及它和客运模型建模的差异,对三种货运建模方法,即四阶段建模方法、出行链建模方法和非集计的仿真模拟进行了阐述,并分析了这些方法的优缺点。此外,探讨了基于投入产出表的产业链分析、基于货运类型的货运建模分析、基于货物分类的货运建模分析以及货运出行与用地的关联建模等构建思路,并以深圳市、广东省和武汉市为例,介绍了实践中建立货运模型的方法和步骤。

The purpose of this paper is to explore different perspectives on freight traffic modeling strategies and the gains and losses in quantitative freight traffic demand analysis.The paper introduces the current status of freight traffic modeling research and the differences between modeling and passenger transportation modeling,it then describes three freight modeling approaches:four-stage modeling approach,travel chain modeling approach,and discrete modeling approach,and analyzes the advantages and disadvantages of these approaches.In addition,this article discusses the construction ideas of input-output table-based chain analysis,freight modeling analysis based on freight type,freight modeling analysis based on cargo classification,and the correlation modeling of freight travel and land use.Taking Shenzhen,Guangdong Province and Wuhan City as examples,the article introduces the methods and steps of freight modeling in practice.
