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...
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....
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...
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...
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...
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...
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...
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...
Selection of Optimum Route and Number of Stations for the Seoul-Pusan High Speed Rail System
The construction of the 411 km-long Seoul-Pusan high speed rail line began in June 30, 1992. The line connects Seoul and Pusan which are the first and the second largest cities in Korea....
Maglev Sensor and Communications System Integration
This paper presents an assessment of the communications and sensor technology integration necessary to assure safety of high-speed transportation on the ground. Candidate architectures...
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...
The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm2....
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...
What Happened to High Speed Rail in Florida?
This paper presents a critical analysis of the 1980s Florida endeavor to develop by private sector franchise America's first true high speed rail system, its failure, and some lessons...
