The Utah Department of Transportation (UDOT) must have accurate accident statistics for different highway classes to improve the safety of the Utah highway system. Although UDOT keeps a complete accident database, it does not reveal commonalities and trends behind accidents. In addition, Utah traffic facilities and services change over the years, emphasizing the need to evaluate the Utah Highway Networks' Functional Classification System. This study measures the safety of different Utah highway functional classes (FCs) according to traffic patterns, traffic volume, geometrics, and travel speed. It presents a process to analyze accident data for different FCs. It also produces the expected accident range in order to identify locations with high accident rates. (Author/publisher)
