The New York State Department of Transportation (NYSDOT) maintains an inventory of over
17,000 highway bridges across the state. These bridges are inspected biennially or more …

This report describes the development of bridge element deterioration rates using the
NYSDOT bridge inspection database using Markov chains and Weibull-based approaches …

The accurate prediction of the future condition of bridge components is an important part of
any bridge management system. Past bridge inspection data along with information on any …

This paper describes methods for determining and utilizing Markov chains in the evaluation
of highway bridge deterioration. Using a data base of 850 bridges in New York State …

This paper describes a statistical approach to estimating an appropriate inspection interval
for highway bridges based on historical condition data collected from 20 years of routine …

A method for estimating transition probability is applied to the deterioration models of a
bridge management system. Deterioration is modeled as a time-dependent function of the …

Timber bridges require high accumulated maintenance costs, which can be many times
greater than their initial cost. Infrastructure managers need deterioration models to assist …

Bridge management has been a subject of intense interest and development for the past 10
years. In support of improved bridge management, FHWA funded the development of the …

In this paper, a methodology to estimate the Markovian transition probability model is
presented to forecast the deterioration process of bridge components. The deterioration …

This paper presents an investigation of the Markov property underlying the stochastic
deterioration models for highway bridges, including transition probabilities between the …
