Abstract
Each update to a Strategic Highway Safety Plan (SHSP) can require a large amount of time, resources, and funding. From the requirements in U.S.C.148(a)(13)(E-F), in the SHSP update process states must consider the results of other transportation planning processes and develop a list of strategies to reduce or eliminate fatal and serious injury crashes (United States, 2023). To fulfill these requirements more efficiently and to gain the largest amount of benefit from said research, this thesis asks the question: how do we select other state transportation plans to study for ideas on improving our own SHSP? In this thesis, a k-means clustering method is proposed to group states based on a variety of factors. These include state demographics, roadway attributes, highway safety performance, and SHSP characteristics. Specific clusters of states can then be selected based on other states that share characteristics most like our own, or based on other states that have the best safety performance. Then, in future studies, the smaller group of states selected can be studied for successful safety improvement programs that have been implemented to gain ideas for improving our own state’s next SHSP. As a case study, the methodology and resulting conclusions are applied to Kentucky in this thesis.
