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. Account access is required. Organizations can subscribe to the MDSS service through DTN to enable access for their personnel. Contact DTN for subscription information.
