  1. X-DSS Concept:Extending Core Capabilities MDSS Stakeholder Meeting Falls Church, VA August 10-11, 2006 Paul Pisano, Team Leader Road Weather Management Federal Highway Administration Washington, DC

  2. Extending MDSS to X-DSS • The MDSS prototype was envisioned & designed to be modular • Many of the MDSS core components could be utilized in DSS for different transportation operations • This vision of “eXtending” the MDSS core capabilities has been coined as X-DSS or the eXtensible Decision Support System • The extensibility allows the “X” to imply association with different operations

  3. MDSS Modularity Data Fusion & Integration Observations & Models User Interface Customization Algorithms

  4. Introducing X-DSS • Builds upon the core capabilities of the base MDSS (reduces development costs) • Expands this investment to other operations within surface transportation: • Summer Maintenance • Traffic Management • Construction • Will require creation and participation of new stakeholder groups

  5. X-DSS for Summer Maintenance Support for: • Mowing – rain locations, fog/visibility predictions, lightning locations • Lane Striping – rain & temperature forecasts, chances of strong winds • Surface Repairs – fog/visibility forecasts, precipitation timing, lightning location, temperature forecasts • Herbicide Application – pavement & sub surface temperature forecasts, frost prediction, wind speed/gustiness & visibility

  6. X-DSS for Traffic Management Support for: • Non-winter weather events – thunderstorms, route-specific flash flood guidance • Road closure planning based on flooding potential • Tactical information to assist repair crews – radar, lightning location, severe weather potential & timing

  7. X-DSS Applications (1 of 2) • Crack Seal Applications • Chip Seal Applications • Thin Hot Mix Application • Fog Seal Application • Microsurfacing Application • Joint Sealing Portland Cement Pavements • Diamond Grinding of Portland Cement Concrete Pavements

  8. X-DSS Applications (2 of 2) • Dowel-Bar Retrofit for Portland Cement Concrete Pavements • Partial-Depth Repair of Portland Cement • Full-Depth Repair of Portland Cement • Hot In-Place Asphalt Recycling • Cold In-Place Asphalt Recycling • Slurry Seal Application

  9. Future Plans (1 of 2) • During FY 2007 • Hold 2 stakeholder meetings • Summer Maintenance (inclusion of SE States) • Traffic Management • Perform abbreviated requirements gathering following the STWDSR model • Have NCAR design modifications to the core MDSS functions and GUI • Determine if the MDSS business model is reasonable for X-DSS

  10. Future Plans (2 of 2) • Reach out to other public agency personnel while continuing to work with the core stakeholder group • There will continue to be an emphasis on modularity, open systems and building the marketplace
