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...
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...
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....
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...
Method for Understanding the Characteristics of Coastal Zones from Historical and Geographical Viewpoints
Through this model investigation of the Miura Peninsula, it was found that collection of various kinds of coastal zone geographical information in the format of a CZCT is useful for understanding...
An Interagency Approach to Beneficial Uses of Dredged Material
Environmental considerations resulted in the development and planned implementation of environmentally beneficial dredged material disposal in connection with U.S. Army Corps of Engineers'...
