Fuzzy Sets Model for Evaluation of Bridge Projects
This paper presents the formulation of a computerized decision support system that would aid the bridge engineer in long range planning of bridge funding needs, specially, to select the...
Uncertainty in Infrastructure Management
The difference between committed costs and actual expenditure is a margin of control in project management. By using a measure of uncertainty we construct a cost-risk evaluation framework...
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...
Risk Analysis Methodology for Life Cycle Benefit Analysis of Innovative Construction Technologies
The adoption of new construction technologies into practice moves very slowly since participants in the construction processes are extremely risk adverse. Innovation barriers are characterized...
An Application of Scour Hazard Analysis and Management
A phased study for the assessment of bridge scour vulnerability is presented. Its objectives are to: (a) initiate a field assessment program, (b)establish data handling capabilities, (c)...
Sensitivity Analysis of Financial Forecasts for MBTA Infrastructure Investment Program
This paper describes a financial analysis methodology and model developed for the Massachusetts Bay Transportation Authority (MBTA), which provides comprehensive projections of the relationships...
Planning for Electronic Toll Collection
With major plans for toll plaza expansion to accommodate growing patronage, the Florida Turnpike had to consider options for reducing future right-of-way acquisition and still provide...
Implementation of the Indiana Bridge Management System
Management of a bridge system involves a complex decision-making process. A comprehensive bridge management system provides a set of tools that aid this process by selecting improvement...
A Short-Term Demand Forecasting Model from Real-Time Traffic Data
Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions...
Implications of Uncertainty in Transportation Control Measures: A Case Study of the Los Angeles Truck Management Program
The Los Angeles Department of Transportation has proposed a peak period travel restriction aimed at heavy-duty trucks on all Los Angeles streets. The ordinance is designed to reduce the...
Case Study of Electronic Toll Collection in the Central Artery/Tunnel Project?Boston
The purpose of this paper is to discuss the issues involved in incorporating new technology, specifically electronic toll collection into a large, long-term construction project. The paper...
Use of Fuzzy Theory for Dealing with Uncertainty: Evaluating Alternatives Under Uncertainty
A method to deal with uncertainty which is associated with vagueness and ambiguity is presented. Fuzzy sets are introduced to account for vagueness in expression and fuzzy measure is introduced...
Overview of Current U.S. HSGT Planning
As an introduction to the subject of high-speed ground transportation (HSGT) and to help put the rest of the conference papers in context, two plenary sessions provided an overview of...
High Speed Transportation for the 21st Century: Florida's High Speed Rail and Maglev Projects
This paper presents a brief status report on the State of Florida high speed ground transportation efforts. It includes a description of the amended high speed transportation act in Florida...
Experience in the Planning of High Speed Rail Lines: From Feasibility Studies to the Construction Project
For the construction of a new line for high speed traffic, a series of technical, commercial and economic studies must be carried out for each of the parts of the planning stage: the feasibility...
Establishing a HSGT System Organization
Most of the attention on High Speed Ground Transportation systems thus far has been devoted to their technological, financial and construction aspects, and this was understandable since...
High Speed Rail: An Alternative Route to Preserve Quality of Life in the Northwest
The impacts of population growth threaten quality of life in the Pacific Northwest. Existing transportation systems cannot meet projected demand nor special needs of an aging society....
Land Use Planning and HSGT Station Development: The Maglev Grand Terminal/International Drive Experience
In 1996, the Future arrives in Orange County, Florida. It is the ribbon cutting ceremony for the high-tech, high-speed ground transportation magnetic levitation train, connecting the Orlando...
