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...

Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...

Maintenance Management of Power Transmission Lines
An adb-based maintenance management system, KUHA, was developed in Finland to enable more efficient maintenance of power transmission lines. The system is used for strategic planning in...

Planning Maintenance and Rehabilitation Activities for Local Railroads
This paper presents a structured approach for planning annual and long range (multi-layer) maintenance and rehabilitation (M&R) activities for local railroads. A method is presented...

An Application of MCDM to Product-Based Pavement Management
The Finish National Roads Administration is currently developing it's organization to be more object-oriented and profit-making. This renewal implies to so called product-approach. In...

Comparison of Aqueduct Reconstruction & Tunneling
The Massachusetts Water Resources Authority (MWRA) is proposing to provide redundancy for the Hultman Aqueduct which transports water over a distance of roughly 27 km. (16.9 mi.) into...

Combining Symbolic and Algorithmic Methods for Capital Budgeting in Highway Rehabilitation
The Pavement Rehabilitation Analysis and Design Mentor (PARADIGM) is a prototype, microcomputer -based, integrated set of interacting expert systems and algorithmic models. This paper...

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...

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...

MIS for Implementing Multi Project Programs
The successful implementation of large or small capital improvement programs must include more than the management of schedule and cost. An effective Program Management Team must be concerned...

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...

An Overview of Markovian Models for Bridge Management Systems
The typical infrastructure maintenance decision-making environment involves multiples objectives, uncertainty, and dynamics of the most commonly used infrastructure models, which captures...

The Finnish Bridge Management System
A computer-based Bridge Management system, BMS, was designed in Finland by the Finish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...

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...

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...

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...
