The storm Gudrun hit southern Sweden in January 2005 and approximately 70 million cubic meters of forest was wind felled. The existing logistic planning at forest companies in the damaged area had to be changed over night. There was a direct shortage of both harvest and transportation capacities. Key questions that arised were which terminals to use, where to harvest, where to store, which tran...

New transportation systems have always attracted attention of both transportation experts and general public: the first railway in England, first automobile and streetcar in Germany, first airplane in the United States all of these inventions attracted excitement, curiosity, enthusiasm and skepticism. With time, many inventions fulfilled or exceeded expectations: they have been developed into m...

Transport is one of the most relevant elements for the competitiveness of companies and cities. An inadequate transportation system generates high costs and low customer service levels, which ultimately produces a negative economic impact for both. This article presents an overview of the technology tools that are part of the Intelligent Transportation Systems (ITS) used to improve the performa...

A weighted coloured–edge graph is a graph for which each edge is assigned both a positive weight and a discrete colour, and can be used to model transportation and computer networks in which there are multiple transportation modes. In such a graph paths are compared by their total weight in each colour, resulting in a Pareto set of minimal paths from one vertex to another. This paper will give ...

We consider a problem in which a supplier must determine the transportation mode for product deliveries to satisfy demand from a set of retailers. Based on combinations of four possible transportation modes, we consider seven different distribution policies on set of instances derived from data from an Italian company. For three demand scenarios (low, moderate, high), we compare the performance...

This Chapter focuses on Intermodal Freight Transportation, broadly defined as the transportation of a load from its origin to its destination by a sequence of at least two transportation modes, the transfer from one mode to the next being performed at an intermodal terminal. Container-based transportation services are an important part of intermodal transportation and the backbone of internatio...

Spatial Data Development at the Bureau of Transportation Statistics Track: Transportation Author(s): Matthew Sheppard, Patricia Solano, Raquel Wright The Bureau of Transportation Statistics (BTS) is leveraging ArcGIS and ArcIMS tools for critical spatial data development efforts. BTS has implemented an ArcIMS application designed to facilitate the collection and quality review of nonattainment ...

Determining optimal routes for given freight is a core decision in logistics. In intermodal logistics, freight routing has to consider the interfaces between different modes of transportation, such as hand-over offsets, load changes, and organizational procedures. We study this problem from the perspective of Service-Oriented Computing (SOC). We (1) propose representing intermodal transport sys...

As personal transportation is one of the greatest contributors of CO2 emissions, means able to assist travelers in reducing their ecological impact are urgently needed. In this work we focus on travel recommenders that encourage green transportation habits among travelers who have a preexisting interest in taking action to lessen their impact on the environment. We aim to provide urban traveler...

This article proposes a mixed integer non-linear programming model for the optimizing supply chains of importers of waterborne containerized goods from Asia to the USA. This model determines the least-cost strategy for an importer, in terms of ports and landside transportation modes to be used, where costs considered include costs for transportation and handling, pipeline inventory, and safety-...
