DESCRIPTION: The main objective of this study is to determine how the State Rest Areas shut down impacted the fatigue-related highway crashes. The total dollar amount loss due to SRAs shut down will also be computed based on fatigue-related highway crashes in Northwest states. The study findings may help to understand the relationship between SRA shut down and frequency of fatigue-related crashes. The findings could assist states in developing a policy regarding the SRA closures as well as to develop a framework to reduce highway crashes due to driver fatigue. Ultimately, mitigating the drowsy drivers, the US highways will be safer to wide range of highway users.
