Evaluation of Interregional Freight Generation Modelling Methods by using Nationwide Commodity Flow Survey Data

Modelling and Estimating Modal Share in European Transport: a Comparative Analysis Using Interregional Freight Flow Data

International and interregional trade and transport are on the rise and hence, there is a clear need for reliable estimates of transport flows. However, the available databases and estimation methods are not yet satisfactory for analytical and predictive purposes. In this paper we explore the use of different statistical techniques in order to examine the spatial flow pattern of freight transpo...

Freight Modelling: Data Issues, Survey Methods, Demand and Network Models

The paper discusses requirements for freight modelling and presents specific approaches concerning freight surveys, demand and network modelling, rail freight optimisation and freight assignment including: • Surveying methods for collecting road based demand data. • WIVER/VISEVA: a demand modelling system for urban and regional commercial transport. • SPIN: a multimodal network model for interm...

Design for Commodity-by-Industry Interregional Input-Outpu–

In this paper we do not attempt to develop an interregional model. Rather, we propose a mathematical structure of computational framework with which a family of interregional input-output models can be constructed. This family of interregional input-output models encompasses the well-known class of static models that are used to analyse the propagation of demand throughout an economic system di...
