Best Practices for Road Weather Management Version 2.0


Best Practices for Road Weather Management, Version 2.0


Weather threatens surface transportation nationwide and impacts roadway mobility, safety, and productivity. There is a perception that traffic managers can do little about weather. However, three types of mitigation measures?control, treatment, and advisory strategies?may be employed in response to environmental threats and impacts. 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, snow, rain, ice, flooding, tornadoes, hurricanes, and avalanches.
