dc.description.abstractThis research investigates the feasibility of using a commercially available portable weigh-in-motion (WIM) system to improve the spatial representation of axle load data from trucks operating on secondary highways. The research evaluated the validity of axle load data collected from three on-road installations next to comparison load data sources, as well as considering the validity of raw and post-processed data. Analysis revealed that portable WIM data cannot achieve the accuracy standard required of ASTM E1318 type II WIM data, but proper installation, calibration, and post-processing can allow portable WIM to have 95% of loads within +/-36% of comparison loads for GVW, within +/-57% for tandem axles, within +/-87% for tridem axles, and within +/-63% for individual axles. Additionally, aggregation and post-processing of the data can allow selected vehicle statistics, such as fully loaded vehicles or GVW distributions, to achieve higher accuracies, potentially allowing for various indirect applications of the data.en_US
