Transferability of Safety Performance Functions Across Jurisdictions: A Comparison between Minnesota, Ohio, and Washington Using HSIS Data

According to the Highway Safety Information System (HSIS) database, interstate crashes account for 15.3, 22.5, and 23.0 percent of all crashes reported in Minnesota, Ohio, and Washington between 2011 and 2015, respectively. This article reports on a study that developed safety performance functions for interstate facilities from these three states to compare the similarities and differences between each other. The datasets were obtained from the Highway Safety Information System database. A negative binomial regression prediction model was used to estimate crashes across the three states using the same independent variables.
