Abstract:Weather has a significant impact on the operations of the nation's roadway system year round. These weather events translate into changes in traffic
conditions, roadway safety, travel reliability, operational effectiveness and productivity. It is, therefore, an important responsibility of traffic managers and
maintenance personnel to implement operational strategies that optimize system performance by mitigating the effects of weather on the roadways.
Accurate, timely, route-specific weather information allows traffic and maintenance managers to better operate and maintain roads under adverse
conditions. Connected vehicle technologies hold the promise to transform road weather management. Road weather connected vehicle applications
will dramatically expand the amount of data that can be used to assess, forecast, and address the impacts that weather has on roads, vehicles, and
travelers; fundamentally changingthemannerin which weather-sensitive transportationsystem management and operations are conducted. Automated
vehicle technologies have progressed in development and research phases. Weather conditions pose a threat to the safety and mobility of automated
vehicles, and therefore road weather information must be considered when further developing automated vehicle applications. The U.S. Department of
Transportation's RoadWeather Management Program has developed this Concept of Operations (ConOps) to define the priorities for connected vehicle
and automated-vehicle-enabled road weather applications.
