T3 Webinars are brought to you by the ITS Professional Capacity Building Program (ITS PCB) at the U.S. Department of Transportation's (USDOT) ITS Joint Program Office, Research and Innovative Technology Administration (RITA). Reference in this webinar to any specific commercial products, processes, or services, or the use of any trade, firm or corporation name is for the information and convenience of the public, and does not constitute endorsement, recommendation, or favoring by U.S. Department of Transportation.


This webinar will walk participants through the recently updated Best Practices for Road Weather Management, Version 3.0 developed under the Federal Highway Administration (FHWA), Road Weather Management Program. The report captures 27 new, state-of-the-art case studies of systems in 22 states, which build upon previous successes, ultimately improving roadway operations under inclement weather conditions. The speakers will provide an overview of systems deployed within their respective state, discussing operational procedures, transportation outcomes, and implementation issues.


Weather threatens surface transportation nationwide and impacts roadway safety, mobility, and productivity. There is a perception that transportation managers can do little about weather. However, three types of road weather management strategies may be employed in response to environmental threats: advisory strategies, control strategies, and treatment strategies. Advisory strategies provide information on prevailing and predicted conditions to both transportation managers and motorists. Control strategies alter the state of roadway devices to permit or restrict traffic flow and regulate roadway capacity. Treatment strategies supply resources to roadways to minimize or eliminate weather impacts. Many treatment strategies involve coordination of traffic, maintenance, and emergency management agencies. These mitigation strategies are employed in response to various weather threats including fog, high winds, snow, rain, ice, flooding, tornadoes, hurricanes, and avalanches.
