• Abstract:
  Road weather systems collect, analyze, and share weather information to help mitigate the disruptive impact of weather events on the nation’s surface transportation system. Much research and development has been undertaken to advance road weather management practice. Meanwhile, many state and local efforts have aimed to deploy connected vehicle (CV) equipment on the roadside and in vehicles. CV message exchanges present an opportunity to provide vehicle-produced, standardized road weather data to transportation infrastructure owners and operators while standardizing the dissemination of weather-related information to travelers. In particular, road weather systems have the potential to benefit from the data that vehicles may produce and to provide critical information to drivers of those vehicles. It has been several years since any significant research, development, and deployment of weather-related connected vehicle applications have been undertaken. Many weather-related CV standards (such as SAE J2945/3) have been released recently but have not yet had much opportunity to be used in practice. The goal of this project was to determine how the data in CV messages could be utilized to enhance existing use cases or potentially enable new use cases for road weather information. Section 2 of this report outlines the results of initial research, including an overview of CV technology and use cases for CV message data. Section 3 presents a Concept of Operations focusing on message exchanges that will enhance the quality of the weather data used in road weather and traffic management activities.
