Weather-Responsive Transportation Management.

摘要

Nearly twenty five percent of non-recurring delays and congestion on freeways is due to adverse weather conditions. The Federal Highway Administration (FHWA) Road Weather Management Program has been focusing its efforts to better understand the impacts of weather on traffic flow and develop tools for alleviating those impacts. Information about weather and its impacts on the transportation system are currently not well integrated into the operational framework of most transportation agencies. This paper describes three efforts by the FHWA Road Weather Management program to advance the state-of-the practice in weather-responsive transportation management.
