A Graphics-Based System for Urban Roadway Management
This paper describes a graphics-based system for urban roadway management. The main objective of the system is to select the cost effective maintenance and rehabilitation (M&R)...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
A Condition Rating System for Rubble Breakwaters and Jetties
This paper describes one aspect of a series of projects which the U.S. Army Corps of Engineering has undertaken in an effort to improve maintenance management of coastal and navigational...
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...
Large Truck Impacts on the Highway Infrastructure: The Bridge Dimension
Recent U.S. studies have explored the productivity gains of longer combination vehicles (LCV's) and their impacts on highway infrastructure. The area least explored is LCV operations and...
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...
High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...
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...
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...
