Abstract: Transportation infrastructure condition (or distress) can be modeled as continuous or discrete variables. As discrete variables, they are commonly recorded with nonnegative integers. In deterioration models, these variables ...

Abstract: This paper investigates an incremental pavement performance model based on experimental data from the American Association of State Highway Officials road test. Structural properties, environmental effects, and traffic ...

Abstract: Both deterioration and policy optimization models play a key role in pavement infrastructure management. A successful management system requires sound deterioration modeling as the basis for the policy optimization modeling ...

Abstract: The evaluation of the effect of maintenance and rehabilitation (M&R) activities plays a critical role in pavement management systems. A quantification of the treatment effect usually resorts to simple statistical regression ...

Abstract: Weigh-in-motion (WIM) technology has found increasing application in the highway and transportation areas for traffic data collection for the purpose of highway capacity analysis, aiding enforcement and, most recently, ...

Abstract: Deterioration modeling is a key component in a transportation infrastructure management system. It serves to capture and predict the performance of a facility. A sound deterioration model should incorporate: (1) relevant ...

Abstract: Deterioration modeling plays a central role in performance prediction, a key component in transportation infrastructure system management. The deterioration of a facility can be expressed in terms of numerous indicators. ...

Abstract: Most fatigue cracking models in use have been developed using the ordinary least squares (OLS) method. However, fatigue cracking data (or any type of cracking data) consists of censored data since it has a lower limit of ...

Abstract: A recursive nonlinear model was developed for the prediction of pavement performance as a function of traffic characteristics, pavement structural properties, and environmental conditions. The model highlights some of the ...
