FHWA/Mitretek 4 Road Weather Management Program Goals 1. Develop improved weather information systems that meet the demands of all users and operators; 2. Develop improved maintenance technologies for winter mobility, and; 3. Develop traffic operations/incident management procedures under all weather events.

10 Maintenance Decision Support System (MDSS) Project One realization of the STWDSR Operational Concept Definition (OCD) for winter road managers – Set of functions implemented – Set of needs served Continues STWDSR stakeholder alliance – National Labs will develop non-exclusive components – State DOTs will operate – Vendors will provide and integrate into Road Weather Information System (RWIS)

FHWA/Mitretek 14 Our information systems should survive the most severe threats. There has to be an operational continuum from the mundane to the severe. Our physical infrastructure may not survive the most severe threats.

FHWA/Mitretek 18 Evacuation: Floyd Results  3 million (est.) people were evacuated from Florida, Georgia, North and South Carolina, resulting in record congestion problems.  Techniques included:  Mobilizing and prepositioning personnel and equipment,  Opening evacuation shelters,  Executing staged evacuations,  Reversing traffic flow during evacuation,  Altering traffic flow to enable at least one counter-flow lane,  Opening shoulder lanes to traffic and closing roadways,  Disseminating information to evacuees (e.g., residents, tourists),  Communicating with neighboring state agencies.
