Several agencies in the Kentucky Transportation Cabinet make use of data collected by weigh-in-motion (WIM) scales throughout the state. These scales are used to collect traffic counts, weigh vehicles, weigh individual axles, determine vehicle length, classify vehicles, and determine speed. The data is primarily used for planning, law enforcement related to commercial vehicles, and pavement design. This study details the applications of WIM data, and reviews existing literature on how WIM data is used and shared. The study provides survey feedback from other states, specifically about how they use WIM data. It details competing WIM technologies currently on the market, and provides measures of performance along with cost estimates. Details on current WIM locations throughout the state are provided, and plans for future WIM locations are also explained. Recommendations about how Kentucky can better utilize WIM technology and data are provided in the final chapter.
