Development of Statewide WIM Data Quality Control and Axle Load Spectra and Traffic Volume Adjustment Factors for Oklahoma

Oklahoma Department of Transportation (ODOT) operates weigh-in-motion (WIM) stations statewide and is actively adopting portable WIM programs. Recognizing that no comprehensive study has been conducted before to evaluate the quality of WIM data in Oklahoma, this collaborative project aims to develop quality control (QC) metrics and associated software interfaces for checking the quality of statewide WIM data, and to develop site-specific, region-specific, and statewide traffic inputs that are required for the Mechanistic-Empirical (ME) based pavement design in Oklahoma. The project deliverables include (1) a user friendly WIM data software that offers efficient WIM data import capability, data quality review and control functions, data visualization and analysis, and three levels of traffic outputs to meet ME based pavement design needs; (2) a guideline on how often and under what circumstances a WIM station should be calibrated and the supporting software tool; (3) comprehensive database and software interface to incorporate results from completed materials studies by ODOT; (4) software training and technical support during the project period to meet ODOT's special needs in pavement design and analysis. This project lasts for two years, while this report documents the results from Year 1.
