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...
An Integrated Design/Construction Research Program for Infrastructure Rehabilitation
The quality of America's infrastructure today is barely adequate to fulfill current requirements, and sufficient to meet the demands of future economic growth and development. This serious...
Evaluation of Two Automated Thresholding Techniques for Pavement Images
Thresholding of pavement images is an important step towards the design of an automated pavement crack detection system. However, traditional automated thresholding techniques generally...
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...
Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...
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...
Treating Uncertainty in the Design of Horizontal Curves
A model based on expected total cost minimization approach is developed for determining optimal horizontal curvature for highway sections. Expected total cost is defined as the sum of...
Aesthetics in High Speed Rail Projects
Aesthetics is critical to the public acceptance and quality of the experience of a high-speed rail system. Social, functional, visual, kinetic, and symbolic aesthetics have specific design...
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...
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...
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...
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...
