  1. THE FHWA PROGRAMFOR PROTOTYPING ADVANCED DECISION SUPPORT FOR WINTER ROAD MAINTENANCE PAUL PISANO ROAD WEATHER MANAGEMENT COORDINATOR FEDERAL HIGHWAY ADMINISTRATION

  2. Presentation Overview • Summarize Surface Transportation Weather Decision Support Requirements (STWDSR) effort • Highlight STWDSR findings • Review Maintenance Decision Support System (MDSS) project

  3. The STWDSR Process Goals The Highway System Decision Support System Safety Mobility Productivity Environment National Security (Outcomes) STWDSRNeeds, Requirements, Outcomes Performance Requirements on DSS Operational Techniques (Output) User Needs for Information System Resources (Information)

  4. Progress to Date FHWA Weather Team STWDSR V2.0 Road Weather Mgmt. Prog. Operational Concept Description White Paper MDSS Prototype & Ops. Test 00-03 STWDSR Needs (V1.0) Preliminary Interface Reqs. Met. Comm. Stakeholders: State DOTs, National Labs (6), Value Added Meteorological Services (VAMS) STWDSR Project (Mitretek) 1997 2000

  5. Decision Support Needs (V1.0) • Defined “needs” as “decisions” • Covered all surface transportation decision makers • Defined 426 needs • Across 44 decision maker categories • Across 3 scales: planning, operational, and warning

  6. Examples of Needs

  7. Operational Concept Description (V2.0) • Analyzed winter road maintenance decisions • Originally 10 operational scale decisions • Expanded to 53 • Organized into 16 clusters • Defined essential functions (i.e., system requirements) for the Weather Information for Surface Transportation – Decision Support System (WIST-DSS)

  9. Preliminary Interface Requirements (V2.0) • Defines the information resources needed from external sources for decision support. • Synthesizes the Information Taxonomy • 212 items necessary to support winter road maintenance decisions • Three categories: environmental information, transportation state information, and the treatment asset information.

  10. Formation of the MDSS Environmental Threat 212 Data Objects Transportation State Treatment Assets

  11. Prototype DevelopmentThe MDSS Project • Puts STWDSR effort into practice for one user group (winter maintenance managers) • Based on design elements captured in the OCD and information interfaces in the PIR

  13. MDSS Approach • Employ National Labs to develop prototype modules • Iterative development with users and system deployers • Based on open systems principles • Field test
