• Abstract:
  This research addressed the management of pavement friction in Wyoming, focusing on its impact on road safety. The primary objective was to investigate the relationship between pavement surface friction and friction-related traffic crashes. Comprehensive data collection and advanced statistical methods, such as Bayesian analysis, were employed to analyze the relationship between pavement surface friction and traffic crashes, particularly at intersections. The investigation revealed that improved pavement friction is particularly beneficial in high-traffic and geometrically complex road sections, significantly reducing crash frequencies. The study indicates that lower pavement friction correlates with higher crash frequencies, underscoring the need for effective friction management strategies. The effectiveness of different surface treatments was assessed, with results showing that treatments like chip seals and microsurfacing not only extend pavement life but also improve friction, thereby decreasing friction-related crashes. The research also integrated pavement friction management into Pavement Asset Management Systems (PAMS) across state Departments of Transportation, highlighting variability in implementation practices and calling for standardized protocols. This study provides practical recommendations for implementing a robust friction management system. Emphasizing continuous monitoring and proactive maintenance.
