Best Practices for Road Weather Management

BestBest PracticesPractices forfor RoadRoad Weather Management Weather Management Home Acronyms About

Weather threatens surface transportation nationwide and impacts roadway mobility, safety, and productivity. There is a perception that transportation 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. For example, this may include road weather and traffic surveillance to monitor threats to system performance, arterial and freeway management to modify 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 fog, high winds, snow, rain, ice, flooding, tornadoes, hurricanes, and avalanches.

This CD contains case studies of systems and applications employed by traffic managers, emergency managers, and winter maintenance managers to improve roadway operations under inclement weather conditions. Each case study demonstrates the entire information thread, from environmental information to system performance information. This information thread begins with the observation and prediction of weather, road surface, traffic, and other environmental conditions to identify threats to transportation system performance. Based upon credible threat information, managers employ mitigation strategies that improve transportation outcomes. The CD also contains a list of acronyms, online resources, and a listing of road weather publications.
