Winter Road Maintenance Decision Support System (MDSS) Prototype Development Presented by Bill Mahoney National Winter Road Maintenance Decision Support System (MDSS) Prototype Development Presented by Bill Mahoney National Center for Atmospheric Research

MDSS Objective To utilize state-of-the-art atmospheric science and engineering approaches to address and improve MDSS Objective To utilize state-of-the-art atmospheric science and engineering approaches to address and improve the performance of the road maintenance practitioner.

MDSS Goals • Capitalize on existing road weather data sources. • Augment data sources MDSS Goals • Capitalize on existing road weather data sources. • Augment data sources where they are weak. • Fuse data to make an integrated and understandable presentation of road conditions. • Provide diagnostic and prognostic information.

MDSS Goals (continued) • Provide display capability for the condition of the roadway. • MDSS Goals (continued) • Provide display capability for the condition of the roadway. • Develop a decision support tool that provides recommendations on road maintenance courses of action together with anticipated consequences of action or inaction. • Provide all the above on a single platform.
