Aggregate Quarry Operations?From a Railroad's Perspective
This paper describes a study which shows how a railroad company can ensure receipt of a cost-effective, high-quality aggregate product for ballast by monitoring selected quarry operations....
Infrastructure Management Using Geographic Information Systems
Before transportation professionals promote (Geographic Information System) GIS as the answer to infrastructure management, more debate is required. Current GIS packages do not have the...
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...
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...
Sensitivity Analysis of Financial Forecasts for MBTA Infrastructure Investment Program

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...
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...
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...
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...
High Speed Ground Transportation: Some Historical Perspectives
The definition of `high speed' ground transportation is relative to the transportation technology of a period. Thus it might be argued that high speed ground transportation began early...
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:...
Carrying Freight on High Speed Rail Lines
Some basic technical aspects of carrying freight on high speed rail lines are presented. To illustrate certain requirements and considerations, performance comparisons are made using three...
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
