Abstract:Transportation agencies, which are responsible for providing safe, reliable highways throughout the winter season, face significant challenges: Travelers and commercial carriers with demanding delivery schedules expect higher levels of service. Transportation agencies have limited funding and staff. Reliable site- and time-specific reports of road conditions can be hard to get. Some weather conditions—particularly fog, frost, and blowing snow—can be difficult to forecast. Capabilities and limitations of new and innovative maintenance treatments are not fully understood. Agencies are losing their most seasoned maintenance workers, who have experienced diverse weather and treated a lot of roads during their careers. Transportation agencies face environmental challenges to the types and amounts of deicing materials they apply.
