Publication Details

WIM Data Analyst's Manual

General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Surface and Other Considerations

Description: This manual provides information and recommended procedures to be utilized by an agency's Weigh-in-Motion (WIM) Office Data Analyst to perform validation and quality control (QC) checks of WIM traffic data. This manual focuses on data generated by WIM systems that have the capability to produce high quality data. Many of the recommended data QC procedures are dependent upon data containing wheel loads (in conformance with the Type I WIM system requirements of ASTM E 1318). This manual has been developed to ensure that high quality WIM data is collected and used to produce reliable and representative load spectra for input into the Mechanistic-Empirical Pavement Design Guide (M-E PDG) software resulting in reliable and predictable pavement designs. While this is the primary use, there are many other uses including performing checks on data generated by systems that produce only axle load data.
