I-80 in Wyoming is characterized by heavy truck traffic, with an average of 47 percent of heavy trucks in the traffic flow. This research analyzes the impacts of truck traffic along I-80 in Wyoming, as well as mitigation strategies to minimize negative impacts, through analyses of safety and operational implications that result from the interactions between trucks and other vehicles. Various traffic, geometrical, and weather characteristics were found significant to increase truck-related crashes, whereas the presence of climbing lanes was found to have potential safety and operational benefits. The analysis of occupant injury severity in passenger car-truck collisions shows that car drivers are more responsible than truck drivers contributing more severe injuries. The disaggregate modeling approach shows significant differences in both the combination and the magnitude of the impact of variables that justify the importance of examining the injury severity of truck-involved crashes broken down by vehicle types, truck configurations, and driving actions. The crash rate analysis shows a higher tire failure rate for trucks compared to the total tire failure rate considering equal vehicle miles traveled as exposure. Benefit-cost analysis for climbing lane installations indicates that the installation of climbing lanes has a significant potential to improve traffic performances for a 20-year planning horizon, with aggregated benefits significantly outperforming the corresponding costs. Findings from this study are expected to help the Wyoming Department of Transportation and policymakers take necessary actions in reducing truck-related crashes and improve the overall operational performance by targeting appropriate strategies and proper resource allocation.
