In this paper we elaborate on the usage of multi-agent-based simulation (MABS) for quantitative impact assessment of transport policy and infrastructure measures. We provide a general discussion on how to use MABS for freight transport analysis, focusing on issues related to input data management, validation and verification, calibration, output data analysis, and generalization of results. The...

This paper presents a discrete network design problem for optimally designing freight transport network in terms of the efficiency of supply chain. Modelling is undertaken within the framework of mathematical programmes with equilibrium constraints, which first incorporates both supply chain and transport networks explicitly. The upper level determines the best set of actions for transport netw...

Abstract: This paper formulates an inter-regional freight transport model based on the spatial price equilibrium and applies it to Japan. This model covers twenty-three types of goods with eleven different regional industrial structures under the economic equilibrium theory. The unknown parameters of the model are calibrated in the iterative computation process. At the each iterative process, b...

This paper contains a review of the literature on freight transport models, focussing on the types of models that have been developed since the nineties for forecasting, policy simulation and project evaluation at the national and international level. Models for production, attraction, distribution, modal split and assignment are discussed in the paper. Furthermore, the paper also includes a nu...

The convergence of increasingly larger numbers of people and resources within cities is creating a dichotomy between increasing demand and otherwise limited urban freight transport networks (Boerkamps and Binsbergen 1999; TfL 2007; Björklund and Gustafsson 2012; Browne et al. 2012). Such trends have led to efforts to identify the main traffic generators within urban areas in a bid to decrease p...

The subject of this paper is the use of ITS (Intelligent Transport System) with the DSS (Decision Support System) for intermodal transport. The types of ITS are classified with attention to specific mobility sequences for freight movements. Referential freight ITS are the CVO (Commercial Vehicle Operations). Then four management tools are presented: SAP-YARD, CroBIT, UirNet and Access. A classi...

Purpose: Multimodal freight transport developed in the transportation sector as an alternative to unimodal transport faced with the challenges brought by the growing global demand for transporting goods. Multimodal transport is the transportation of goods using at least two modes of transport, usually door-to-door. The common transport modes include railways, maritime routes, and the roads. Whe...

In this paper we present our research works centered on a problematic which attract the attention of many researchers and decision maker, which is the traceability of the product. we are interested more precisely to the traceability in the field of goods transportation, by proposing a modeling approach of the relative data to freight, the result of this modeling, was used in the form of a centr...

The goal of this paper is to combine the current theory about marketing channels with combined transport and logistics in order to develop a customer-based and broadly applicable approach to the study of combined freight transport in Europe. Furthermore, this paper seeks to provide an analytical framework as a starting point for the analysis of the performance-in terms of quality-of intermodal ...

China's freight transport volume experienced rapid growth over recent years, causing great concerns over its energy and environmental impacts. In this study, by establishing a bottom-up accounting framework, a set of scenarios reflecting the possible future trajectories of energy consumption and Greenhouse Gas (GHG) emissions from China's freight transport sector are developed. According to our...
