A Combined Noise Model for HSGT Traffic
Environmental concerns are high on the list of possible problem areas for proposed high speed ground transportation (HSGT) systems. A Federal Highway Administration (FHWA) Highway Traffic...
Estimating the Ground Transportation Impacts of the Maglev System
This paper will examine the planning process required to conduct a transportation analysis for a high speed ground transportation system, utilizing the Orlando experience as an example....
Development of Simulation and Cost Models to Compare HSR and Maglev Systems
Both high-speed rail (HSR) and magnetically levitated systems offer comfortable and safe ground transportation at high speed. The cost structure and performance of these systems and their...
Automation for Design of High Speed Rail Alignments
The widespread industry practice of using civil engineering software modified for the design of High Speed Rail alignment is inefficient and produces inadequate results. Advances in computer...
High Speed Rail Loading Scenario and Dynamic Tuning of Track
Similarities and differences exist between conventional and high speed rail (HSR) infrastructure design. The differences stem from the dynamic nature of the HSR loading scenario and the...
Aerodynamic Resistance of Trains Running Through a Tunnel
In what follows, some previously published results and formulae have been combined in order to obtain an applicable tool for evaluating the energy consumption of trains in tunnel as a...
Dynamic Study on New Guideway Structure for JR Maglev
This paper presents an introduction of the study for the design and technical development of a newly proposed guideway structure for the superconductive magnetically levitated train system...
The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm2....
Implementation and Maintenance of a TGV Line
Because of the success of the TGV in France since the opening date in 1981, SNCF plans to implement 2800 miles of new line in the next 20 years. A new line project poses two management...
The Singularity of Spanish Railway High Speed
The Madrid-Seville line has been the main target in many action programmes pursuing the improvement of its insufficient capacity. In 1987, the Government proposed a high speed line (250...

Structural Engineering in Natural Hazards Mitigation
This two-volume set of proceedings,
Small-Government GIS
Geographic information systems, or GISs, have shown great potential for use as a tool by public engineers working on the state and municipal level, but the time and money required to put...
Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....
Runway Rehab: A Case for CADD
Hired to design and monitor construction at Boston's Logan Airport, engineers at S E A Consultant's quickly realized that they would have to supplement their...
Landfill on Screen
Engineers for a $3.7 million regional landfill in Iowa turned to computer-aided design at every project step from conceptual design through operations monitoring following construction....
Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...
Production and Decomposition of
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...
A Workstation for the Extraction of Coastline from Digital Imagery
The delineation of coastline has primarily been a manual tracing exercise from various forms of imagery. In this paper, a process to extract shoreline automatically from digital imagery...
Vertical Erosion on Beaches and the National Flood Insurance Program
During the 25 years that the National Flood Insurance Program (NFIP) has been in existence, there has been an increasing recognition of the contribution of both episodic and long-term...
