While largely due to conditions outside their control, the configuration and setting of current intermodal rail terminals contribute to congestion and increased freight handling volumes that have resulted in additional transportation costs for shippers and carriers. Although a substantial body of research has focused on improving the efficiency of port operations and multi-modal freight shipmen...

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...

In this project, we explore a data-­‐driven approach for monitoring rail infrastructure from the dynamic response of a train in revenue-­‐service. Presently, rail inspection is performed either visually or with dedicated track geometry cars. We examine a more economical approach where ...

We propose a framework in support of the supply chain network design and management of densified biomass. This framework relies in the use of trucks for short distance biomass transportation, and relies in the use of rail for long-haul, and highvolume transportation of densified biomass. We propose a hub-and-spoke network design model in support of biomass delivery using rail transportation. We...

This paper addresses the design problem of a rail transit line located in a linear urban transportation corridor. The service variables designed are a combination of rail line length, number and locations of stations, headway and fare. Two profit maximization models, which account for the effects of different transit pricing structures (flat and distance-based fare regimes), are proposed. In th...

Railways are considered as the safest means of transportation. But, lots of people suffer due to train accidents. According to a research, derail and collisions occur every ninety minutes. More than 10,000 train accidents had taken place in last eight years all over the world. Reasons for these accidents are human error, signal misinterpretation, system failures, improper maintenance of tracks ...

Human-wildlife conflict is a leading cause of adult mortality for large carnivores worldwide. Train collision is the primary cause of mortality for threatened grizzly bears (Ursus arctos) in Banff National Park. We investigated the use of stable isotope analysis as a tool for identifying bears that use the railway in Banff. Rail-associated bears had higher δ(15)N and δ(34)S values than bears sa...

Control of noise and vibration emitted by steel wheel and rail transportation systems has a long history of designs and techniques, some of which were dismal failures and some which worked very well. Many of the early efforts had a valid technical base for the design, however, there were also many based on intuition or ideas with great expectations, but which had no real technical basis. In the...
