Patterns in the History of the Urban Infrastructure
Infrastructure construction has been marked not only by a cyclical funding pattern but also by occasional shifts in regard to government level of provision. That is, while some infrastructure...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
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...
GIS-Based Applications for Rail Infrastructure Analyses
Computer modeling and analysis techniques are important tools being used to evaluate impacts associated with transporting high-level radioactive waste to the proposed national repository...
AM or GIS for Managing Infrastructure
The two approaches to managing infrastructure are discussed in this paper: Automated Mapping (AM) and Geographic Information System (GIS) It is very important to recognize their similarities...
Addressing Uncertainties in Flexible Pavement Maintenance Decisions at Project Level Using Bayesian Influence Diagrams
Bayesian influence diagrams are directed acyclic graphs used as a network representation for making decisions under uncertainty. These representation facilitate the assessment of coherent...
Projecting Land Use/Transportation Interactions
The inherent uncertainty in forecasting the interaction between transportation capacity and induced development has resulted in insufficient analysis of this dynamic in the transportation...
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...
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...
Evaluation of HSGT Systems Under Uncertainty
The basic themes of this paper are two-fold. First we investigate what planning style is likely to be most suited for planning an HSGT system, dependent on three interdependent key variables:...
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...
Towards a `Simple' Long Term Evaluation of HSGT
The author examines, analyzes, and pursues the roots of several fundamental economic and related theories and techniques commonly used to determine technological performance, its measurement...
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....
California-Nevada Superspeed Train Experience and Outlook
The experience of the California-Nevada Superspeed Train is chronicled from its inception in 1970 to the present. The evolution of the route alignment and technology selection are presented,...
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...
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...
The Effects of HSGT on Urban Decentralization
While promoting a more efficient use of resources, high-speed ground transportation also could retard the process of urban decentralization which has been encouraged by the location of...
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....
Effect of Future High Speed Ground Transportation on Airport Expansion Needs in the State of Washington
A high speed ground transportation system is proposed to be built in the State of Washington to connect all regions. The proposed system will be approximately 700 miles in length and would...
Potential Statewide Impacts of Florida's Proposed High Speed Rail System
This paper presents a summary of the findings from an analysis of the potential statewide impacts resulting from the construction and operation of a high speed intercity rail system in...
