货物运输需求是从生产地点到消费地点之间运输货物所需的所有活动产生的需求，包括贸易、物流和运输。物流在货运需求模型中的良好表现使我们能够预测物流系统变化对未来运输流量的影响。因此，它提供了更好的相互作用的成本估计，并允许更准确地预测货运流量的空间格局的变化。近年来，对货运模型的关注不断增加，出现了旨在将物流纳入货运模型的新研究工作。在本文中，我们回顾了最先进的货运需求模型中的物流考虑的代表性。我们的重点是物流网络变化的服务和成本驱动因素，以及这些因素如何影响货运。我们的审查收益沿着建模的概念框架，超越了传统的4步建模方法。我们确定了有前途的货运建模领域，在这个框架内，如空间可计算一般均衡模型，供应链选择模型和超网络模型的综合功能。
Freight transport demand is a demand derived from all the activities needed to move goods between locations of production to locations of consumption, including trade, logistics and transportation. A good representation of logistics in freight transport demand models allows us to predict the effects of changes in logistics systems on future transport flows. As such it provides better estimations of the costs of interaction and allows to predict changes in spatial patterns of freight transport flows more accurately. In recent years, the attention for freight modelling has been growing and new research work has appeared aimed at incorporating logistics in freight models. In this paper we review the state of the art in the representation of logistics considerations in freight transport demand models. Our focus is on the service and cost drivers of changes in logistics networks and how these affect freight transport. Our review proceeds along a conceptual framework for modelling that goes beyond the conventional 4-step modelling approach. We identify promising areas for freight modelling that have an integrative function within this framework, such as spatial computable general equilibrium models, supply chain choice models and hypernetwork models.
