The MDSS app is a mobile application for the Pooled Fund Study Maintenance Decision Support System (MDSS). It is designed to provide mobile access to information that supports transportation winter maintenance decision making, including route-specific winter maintenance recommendations, weather and pavement forecasts, and observational data to include FAA/NWS and RWIS observations, weather maps, and camera images. Please note that data access by the app is restricted to preauthorized users in select transportation agencies. Information is not available to the general public via this app!
