TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...

Tunnel Repairs Under Traffic and Community Impacts
Maintaining and rehabilitating the nations existing urban infrastructure is vital for the long term economic health of the cities in which the facilities are located. Successful rehabilitation...

Infrastructure Management System: A Novel Approach
Traditional techniques of recording field data, and evaluation usually result in voluminous paper work. To streamline this operation, Sverdrup pioneered the use of an innovative CADD-Graphics...

Automating Inventory and Assessment of Infrastructure
Due to the large amount of information required to describe the components of infrastructure, automated tools are required to speed data collection and access to this information. This...

Traffic Signal Management Utilizing Fiber Optic Cable
Fiber optic cable technology has progressed from the pioneer stage and is becoming a widely accepted method of data transmission. Utilization for traffic signal systems, however, is not...

Modeling the Traffic Flow Impacts of Rehabilitation Activity on Two-Lane Highways
Researchers at the Purdue University have been involved in developing techniques for predicting the operational impacts created by one-way traffic control. These techniques estimate average...

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...

Uncertainty in Economic Evaluation of Upgrading Gravel Surface Roads
Many highway links in the world are still gravel surfaced. As traffic volumes increase, the demand for upgrading these surface also increases. The challenge to highway infrastructure management...

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...

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...

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...

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...
