The efficient and safe movement of freight is one of the important goals of urban transportation systems and vital to not only the local economy, but nationally as well. Given the importance of the freight transportation system, opportunities to utilize state of the art Intelligent Transportation Systems (ITS) technologies are increasing to improve the operation of the existing infrastructure t...

Intermodal freight transport has received an increased attention due to problems of road congestion, environmental concerns and traffic safety. A growing recognition of the strategic importance of speed and agility in the supply chain is forcing firms to reconsider traditional logistic services. As a consequence, research interest in intermodal freight transportation problems is growing. This p...

In the freight car dispatching problem empty freight cars have to be assigned to known demands respecting a given time horizon and certain constraints. The goal is to minimize the resulting transportation costs. One of the constraints is that customers can specify the type of cars they want. It is possible, however, that cars of certain types can be substituted by other cars, either in a 1-to-1...

In recent decades transport geography has been transformed by a topical emphasis towards passengers, which I perceive somewhat as a bias. The modes and terminals that support passengers have consequently received the bulk of the attention and parsing the topics presented at conferences such as the AAG confirms this view. Freight transportation has a reputation of being ‘‘uninteresting’’, probab...

In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...

Mr. Chairmen and Members: We are pleased to be here today to discuss challenges in defining the federal role with respect to freight transportation issues. There are concerns that the projected increases in freight tonnage for all transportation modes will place pressures on the marine, aviation, and highway transportation systems. As a result, there is growing awareness of the need to view var...

This primary objective of this paper is to examine the causes for the change in energy consumption in the transport sector in India. The pattern of energy consumption and their causes for change are benchmarked against select countries. A mathematical model that decomposes changes in energy consumption to various factors has been used. The changes in the energy consumption are attributed to gro...

16 Freight movement complexity and a lack of truck trip data limits freight modelling’s practicality 17 and application. Most publicly available truck movement data is reported at higher geographical levels 18 than detailed analysis and modelling require. The current Freight Analysis Framework (FAF) provides 19 freight data based on the Commodity Flow Survey (CFS) conducted every five years wit...
