Abstract:Adverse weather has major impacts on the safety and operations of all roads, from signalized arterials to Interstate highways. Weather affects driver behavior, vehicle performance, pavement friction, and roadway infrastructure, thereby increasing the risk of crashes. Most literature on weather effects have focused on collision risk, traffic volume variations, signal control, travel pattern, and traffic flow parameters. However, there is limited literature that characterizes vehicle performance under adverse weather conditions at different levels of automation. This paper discusses the relationship between weather and automated vehicle (AV) performance, including challenges caused by weather, data that can help alleviate some of these challenges, and new road weather data generated by AVs. Additionally, the U.S. Department of Transportation (USDOT) Road Weather Management Program (RWMP) has invested in several research efforts that support real-time road weather information. These efforts are very valuable and could play an important role in the development of advanced safety applications for automated vehicles
