Promoting Management Systems Within Organizations
The major effort during the years in which pavement management emerged as an accepted practice was making refinements to the technical models and techniques in the systems. For example,...
Algorithm for Crack Detection in Automated Pavement Analysis
This paper summarizes recent research in various algorithms for detection of pavement cracks. The most successful algorithms use a digital filter to obtain an approximation of the principal...
Modeling the Spatial Structure of Facility Condition
This study develops methods for information extraction that he bridge the gap between the detailed condition data collected by advanced technologies and the information necessary for maintenance...
A Graphics-Based System for Urban Roadway Management
This paper describes a graphics-based system for urban roadway management. The main objective of the system is to select the cost effective maintenance and rehabilitation (M&R)...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
Optimization of a Maintenance Station Network
This report is about a method for optimizing maintenance station and storage networks for maintenance of various traffic channels like streets, roads and sea channels. The results that...
Economic Paradigms for Infrastructure Management
A key characteristic which has emerged in infrastructure management system is the use of economic models at the network level (as opposed to project level) to help in evaluating program...
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...
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...
Neural Network System for Automated Highway Pavement Inspection
A multi-layer perceptron back propagation neural network based methodology has been developed to process and analyze moire fringes obtained with an automated highway pavement inspection...
Inspection and M&R Decisions for Infrastructure
This paper reviews different possible mathematical formulations for a joint inspection and M&R decision-making model, having various levels of restriction and computational complexity....
Pavement Network Level Management Using Micro PAVER
This paper presents pavement network level management using Micro PAVER with emphasis on pavement condition prediction modeling and annual and long range work planning....
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...
Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...
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...
Identifying a New Role of the Future Planner
It has been amply demonstrated over the last three decades that public planning is subject to great uncertainties, both in dealing with new technologies as well as in dealing with fuzzy...
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...
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...
Use of Fuzzy Theory for Dealing with Uncertainty: Evaluating Alternatives Under Uncertainty
A method to deal with uncertainty which is associated with vagueness and ambiguity is presented. Fuzzy sets are introduced to account for vagueness in expression and fuzzy measure is introduced...
