Intelligent Transportation Systems (ITS) apply advanced technology to the nation’s transportation needs. ITS encompasses all areas of transportation, including highway, air, water, and bus and rail transit applications and technologies; both within a single system, and within integrated, intermodal systems. New technologies from such fields as information processing, electronics, control system...

This study defines a methodology to compute unitary costs for freight transportation modes. The main objective was to gather relevant costs data to support the formulation and evaluation of railway, road, pipelines and port projects. This article will concentrate on the following steps: Compilation and analysis of relevant modal cost studies, Methodological adjustments to make cost figures comp...

Various indicators are used to qualify the performance of intermodal transportation systems. Some of these are found in public documents, e.g., annual company reports, usually providing global measures such as total flow volumes, profits, and share values. While of great interest, such measures are not sufficient to support a fine analysis of different operation strategies, commercial policies,...

Passengers travelling in public transportation networks often have to use different lines to cover the trip from their origin to the desired destination. As a consequence, the reliability of connections between vehicles is a key issue for the attractiveness of the intermodal transportation network and it is strongly affected by some unpredicable events like breakdowns or vehicle delays. In such...

We study a multicommodity routing problem faced by an intermodal service operator that uses ground and maritime transportation. Given a planning horizon, a set of commodities to be picked up at their release times and to be delivered not later than their duedates, the problem is to decide on routes for these commodities using trucks and scheduled and capacitated maritime services at minimum cos...
