Findings from LTPP SPS WIM Systems Validation Study

Findings from weigh-in-motion (WIM) validations conducted at 24 Long-Term Pavement Performance (LTPP) Specific Pavement Study (SPS) test sites are presented in this paper. The test sites spanned 21 states in the U.S. The authors identify trends observed between sites, which were equipped with different WIM systems, and offer recommendations on improvements for WIM system verification and calibration processes. By analyzing the performance of SPS WIM equipment, research quality data can be obtained, and it can be determined whether WIM system accuracy is a function of pavement smoothness, speed, temperature, truck characteristics, and WIM sensor type. Additionally, the effectiveness of current processes for validation of SPS WIM scales can be determined and recommendations can be made for improving the validation process.
