This paper proposes a micro-simulation model for urban freight movement, in which the behavior of freight agents and their relationship in supply chains are incorporated. The proposed model is a modification of the traditional four-step approach in that it considers the behavior of each freight agent individually. This paper covers three of the four steps of the traditional approach, including ...

Considerably less research has been done on modeling freight demand with disaggregate discrete models than on modeling passenger demand. The principal reason for this imbalance is the lack of freight demand data. Freight demand characteristics are expensive to obtain and are sometimes confidential. This paper analyzes the freight demand characteristics that drive modal choice by means of a larg...

We analyse maintenance cost data for Swedish railway infrastructure in relation to traffic volumes and other characteristics, and separate the cost impact from passenger and freight trains. Lines with mixed passenger and freight traffic, and dedicated freight lines are analysed separately using both log-linear and Box-Cox regression models. We find that for mixed lines, the Box-Cox specificatio...

ITE JOURNAL / DECEMBER 2004 INTRODUCTION AND SCOPE OF PAPER Planning for freight transportation in urban areas is not performed as commonly or as thoroughly as planning for passenger transportation, despite the fact that one of the seven factors for metropolitan planning specified in the federal legislation (the Transportation Equity Act for the 21st Century) mentions freight. Most planners and...

The purpose of this paper is to provide an overview of how the intelligent transportation system (ITS) supports freight transportation operations. A study of the literature on transportation information and communication technology (ICT) and intelligent (or smart) transportation systems has been conducted. Documents of more than 60 companies producing or using intelligent transportation technol...

Freight transport is the output of an economic market, which converts commodity flows into vehicle flows. Interactions in this market influence vehicle flows and since freight market characteristics (product differentiation and economies of scale/scope) violate perfect competition conditions, the output of this market cannot be predicted directly, unless these interactions are represented in th...

We analyze a continuous review stochastic inventory model in which orders placed with a make-to-order manufacturer can be shipped via two alternative freight modes differing in lead-time and costs. The costs of placing an order and using each freight mode exhibit economies of scale. We derive an optimal policy for utilizing the two freight modes for shipping each order. This freight mode decisi...

Developing the country’s economic is a hot topic in Chinese society, and then the freight ability is a value that show the development of the local economic. The prediction of freight ability in country is benefit to the planning of country’s transport. This article choose suited input first, and then make up the GRNN model, at last ,predict the ability of the freight.

The geography of freight transportation evolves at various scales, but it is increasingly acknowledged that freight flows occurring at the local level are a result of global and regional economic processes. Internationally, distribution networks have expanded, namely through the division of production, manufacturing and consumption. This has been accompanied by a growth of the quantity of freig...

This paper written for IMPRINT [IMPRINT, 2001] addresses the concerns of the freight transport with respect to urban pricing schemes. The viewpoints of the transport stakeholders, the limited reaction possibilities within the goods collection and distribution processes as well as the cities interests are presented for the different pricing motivations: the fair charging of infrastructure cost, ...
