Research Needs for Weather-Responsive Traffic Management

Abstract

In weather-responsive traffic management, weather events are viewed as nonrecurring incidents that can be predicted and observed and have effects that can be mitigated. Weather impacts on traffic flow are reported, and an emerging concept of operations for a systemwide approach to traffic management in adverse weather is described. This approach is structured to assess weather impacts and implement operational strategies that improve safety, mobility, and productivity. Finally, research needs to advance the state of the practice in weather-responsive traffic management are enumerated.
