Characterization of traffic load and local calibration of the MEPDG for New Mexico
… these WIM sites are evaluated for their use for local calibration of the MEPDG. An algorithm is developed in Visual Basic Application (VBA) to check the quality of WIM data. In essence, frequency distributions of the gross vehicle weight and the front steering axle weight are calculated and …

Local calibration of the MEPDG prediction models for pavement rehabilitation and evaluation of top-down cracking for Oregon Roadways
… sections throughout Oregon were included in this calibration study. A detailed comparison of predictive and measured distresses was made using the MEPDG released software Darwin M-E (Version 1.1). It was found that Darwin M-E predictive distresses did not accurately reflect measured distresses, …

Validating the empirical distress prediction models within the AASHTOWare Pavement Mechanistic-Empirical Design, using Tennessee pavement performance data from the Long Term Pavement Performance database
… national data, necessitating validation and local calibration before implementation on a local scale. Moreover, updates to PMED present possibilities for continuous evaluation to account for improvements in the distress prediction models. This study validates PMED version 2.6.2.2’s prediction …

Testing methods for calibrating Forest Vegetation Simulator (FVS) diameter growth predictions
… systems, FVS was designed to include an internal calibration algorithm that makes use of growth observations, when available, from permanent inventory plots. The basic idea is that observed growth rates on a collection of remeasured trees are used to adjust or "calibrate" FVS diameter growth …

Evaluation of climate data sources and investigation of performance prediction models for mechanistic-empirical pavement designs
… previous versions that warranted the need for re-calibration for state-specific conditions (commonly known as local calibration) using the latest version of the software (version 2.5.5 released in June 2019). Evaluation of nationally-calibrated models is performed for flexible, rigid and asphalt …

Verification of asphalt concrete performance prediction using level 2 and level 3 inputs of mechanistic-empirical pavement design guide for flexible pavements of the state of New Jersey
… this study will be effective in facilitating the local calibration of the M-EPDG, a critical step towards implementation of the M-EPDG for other state agencies.</p>

Risk Analysis and Reliability Improvement of Mechanistic-Empirical Pavement Design
… tasks were accomplished in this research. First, local calibration using 38 pavement sections was completed to reduce the system bias and dispersion of the nationally calibrated MEPDG. Second, uncertainty and risk in the MEPDG were identified using Hierarchical Holographic Modeling (HHM). To …

Sensitivity of MEPDG Using Advanced Statistical Analyses
… designs and analyze performances as well as for local calibration of MEPDG.

Improved dynamics modelling for drainage sediment prediction and management
… a model with reduced likelihood of inappropriate calibration.<br/><br/>In verification tests, the combined sediment prediction model was found to be able to predict the location of sediment deposits to a level of accuracy suitable for allowing operational decisions to be made. Under quantitative …
