GLOBALOG: A simulation case of freight multimodal transportation
Authors: Rosa Rios Prado, Diego Crespo Pereira, David del Rio Vilas, Nadia Rego Monteil
Abstract
GLOBALOG is a Spanish multidisciplinary project aimed at promoting logistics as a competitiveness factor. This paper presents the work carried out for the modelling and long-term analysis of multimodal transportation networks, leading to the first complete multi-regional maritime-road multimodal freight transportation model in Spain. The classical four steps approach has been adapted to the specific characteristics of multimodal freight transportation and the available data sources. Road and maritime-road multimodal mode choices have been analysed and fitted to a model based on historical data. Along with provided origin- destination matrices, a model for mode distribution forecasting has been implemented in the TransCAD transport planning software. A set of scenarios of cuts in port services fees and reductions in maritime transportation times has been analysed. Although several data pitfalls raise concerns on the validity of the numerical results obtained, this paper demonstrates the potential of this methodology for the improvement of multimodal networks.
