Current Practices in Transportation Management During Inclement Weather

摘要

The Road Weather Management Program of the Federal Highway Administration (FHWA) has documented transportation management practices used during inclement weather. Best management practices include road weather and traffic surveillance to assess threats to transportation system performance, arterial and freeway management to regulate roadway capacity, as well as dissemination of advisory information to influence traveler decisions and driver behavior. These management practices are employed in response to various weather threats including low visibility, high winds, precipitation, hurricanes, flooding, and avalanches. Weather-related transportation management practices (1) improve mobility by increasing roadway capacity and promoting uniform traffic flow, (2) increase public safety by minimizing accident risk and exposure to hazards, as well as (3) enhance the safety and productivity of road maintenance personnel.
