Motorcycle Safety Assessment in Wyoming and Utah: Crash Characteristics and Contributing Factors

Even though motorcycle fatalities comprise a large percentage of traffic fatalities in the U.S. (in excess of 15%), comprehensive studies on motorcycle safety on the national level are lacking. From 2015 onwards, the 5-year rolling average of fatal motorcycle crashes per million population in Wyoming has been increasing, from 26 in 2015, to 32 in 2018. In 2018, there were 15 motorcycle fatalities in Wyoming. In Utah, the average motorcycle fatalities between 2015 and 2020 were 41 per year, which constituted about 15.1% of all highway fatalities. This research will perform a comprehensive motorcycle safety assessment for Wyoming and Utah, using five to ten years of detailed crash data. It will analyze crash characteristics, severities, types and contributing factors for different facilities and area types, and assess the countermeasures which have the potential to reduce the frequency and severity of motorcycle crashes. The study will develop statistical models to be used for a detailed assessment. There aren't any recent studies on motorcycle safety in Wyoming and Utah, however fatal and serious motorcycle crashes represent a significant percentage of all crashes. A comprehensive study is needed to determine motorcycle crash characteristics, contributing factors and potential countermeasures.
