Abstract:

M Mahdi Rezapour Mashhadi (ORCID iD: 0000-0003-0774-737X); Promothes Saha, Ph.D., P.E. (ORCID iD: 0000-0003-3298-8327); Trenna Terrill (ORCID iD: 0000-0002-5239-6380); Khaled Ksaibati, Ph.D., P.E. (ORCID iD: 0000-0003-3532-6839) Wyoming has one of the highest large truck crash rates in the country. This is due to a variety of reasons which include: the significant amount of through truck traffic on I-80, adverse weather conditions, and the challenging geometric conditions. The main objective of this study is to develop mitigation strategies to reduce these high truck crash rates and provide recommendations to the agencies that can help enhancing truck-related safety. These agencies includes: the Wyoming Highway Patrol (WHP), Wyoming Department of Transportation (WYDOT), and trucking industry in Wyoming. All interstates in Wyoming (I-80, I-25 and I-90 totaling 910 miles) and three state highways (US 26, US 30 and Wy 59 totaling 337 miles) were included in this study. A variety of datasets including: crash data, traffic volumes, traffic citations, roadway geometry and enforcement data were investigated. Various statistical modeling techniques were successfully implemented to identify factors behind truck-related crashes. A crash and citation hot spot analysis were conducted to develop a strategy to shift enforcement resources. In addition, an enforcement analysis were conducted to estimate the effectiveness of highway patrol resources by comparing the highway patrol personnel, budget and percent time patrolling from seven surrounded states of Wyoming. Finally, this study provided recommendations to the three different agencies mentioned above. The recommendations to WHP focused on where and when to provide more enforcement and which type of enforcement is more effective in reducing truck-related crashes. The recommendations to WYDOT included safety countermeasures to help reduce truck-related crashes. The recommendations to the trucking industry concentrated on information that should be included in the safety training to educate truck drivers in reducing truck-related crashes.
