Using Condition Indexes to Evaluate Local Railroad Track Networks
The U.S. Army Construction Engineering Laboratories (USACERL) have developed condition indexes for assessing track condition that apply to local railroads. Indexes were developed for the...

Highway Maintenance and Integrated Management Systems
Maintenance management systems were among the first applications of rational management principles and the (then) the new technology of computers to highway operations. Recent changes...

TRACK(1.0): A Railroad Track Design and Evaluation Computer Program for Work Planning and Budgeting
This paper describes TRACK, a track structural analysis method and computer program developed by the U.S. Army Construction Engineering Research Laboratories. TRACK is a program for evaluating...

Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...

Infrastructure Planning in Beirut, Lebanon
This paper presents a comprehensive framework for structuring the decision process of planning for transportation infrastructure rehabilitation and development in the city of Beirut, Lebanon....

Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...

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...

The Megabight Barrier / Maglev Way?Innovative Siting of High Speed Ground Transportation...Offshore
Air and road traffic congestion around cities, e.g., in the BOSWASH corridor, can be reduced by high speed rail systems. But high speed trains on elevated rails/guideways encounter extra...

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...

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...

Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...

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...

Hydraulic Design of Reversible Flow Trashracks
This monograph, Hydraulic Design of Reversible Flow Trashracks, consolidates the body of information on reversible flow trashracks into a design...

Lifelike Model
Data from about 400 structures in the San Francisco Bay Area were recorded during the 7.1 Richter-scale Loma Prieta quake. Among these structures was a 49-story office tower in downtown...

Shelter from the Storm
Assuming that EPA meets its most recent deadline (Octobet 31, 1993), municipalities (cities and counties) with populations of less than 100,000 that own or operate separate storm-water...

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...

Energy Facility Siting in Coastal Zones
Siting constraints to the development of coastal energy facilities may lengthen or complicate the siting process. These constraints have evolved over the history of coastal energy facilities....

Argentine Deltas Morphology
Only two deltas are located along the Argentine coast, both of them at Buenos Aires state. The northern one is the Parana Delta at the Rio de La Plata estuary (34.99' Lat. Sur) and the...

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
