The broadband wireless access is emerging as a promising technology to meet the ever-increasing demand of M-commerce on the train. The traditional railroad communication system (RCS) is not only in charge of the traditional train scheduling, but also offers broadband WLAN services to passengers and provides the network platform to the intelligent railroad information system. This imposes a majo...

The current guidance provided for alignment studies stems largely from Wellington’s “Economic Theory of The Location of Railways” which discusses the problem of minimizing grades and curves on a transcontinental scale. However, modern engineers often find themselves working on a less grand scale with shorter projects such as industrial spur build-ins and urban by-passes, and needing to consider...

Even though rail transportation is one of the most fuel efficient forms of surface transportation, fueling costs are one of the highest operating cost head for railroad companies. In US, unlike Europe, fueling costs are indeed, by far, the single highest operating cost. For larger companies with several thousands of miles of rail network, the fuel bills often run into several billions of dollar...

DESIGN A retrospective, descriptive study. SETTING Retrospective record review. PARTICIPANTS Conducted using 156 records from the Florida Silver Alert program for October 2008 through...

A “ nd as it came, it changed the face of America. Villages which had once prospered because they were ‘on the railroad’ languished with economic anemia; villages on Route 61 bloomed with garages, filling stations, hot-dog stands, chicken dinner restaurants, tearooms, tourists’ rests, camping sites, and affiuence. Slowly, but surely the age of steam was yielding to the gasoline age.’” That quot...

Problem Statement: in the software engineering field, satisfaction of user's requirements by software has been a matter of concern. Therefore, monitoring software behavior against user's highlevel requirements has already received a considerable and significant attention. However, the gap between low-level software behavior and high-level requirements has put an obstacle in the way of monitorin...

Car-to-car communication aims at increased driving comfort and safety. Moreover, it changes the role of vehicles from mere transportation means to “smart objects”. Despite many R&D activities in the last years, this technology still poses multiple challenges on the wireless transmission and network protocols. Aspects like efficient message dissemination, network scalability, and information sec...
