1. Integrating Surface Transportation Weather Information Systems - The DOT Role Transportation Research Board 85th Annual Meeting Session 494: SAFETEA-LU Road Weather Research and Development Program January 24, 2006 Jeffery F. Paniati Associate Administrator Office of Operations Federal Highway Administration

2. 2 Presentation Overview Importance of road weather management in achieving 21 st century operations. Progress to date. Future direction--SAFETEA-LU section 5308.

3. 3 Basic Premise… Build, maintain, and operate a transportation system that is safe, reliable, and secure.

4. 4 Current Reality… BUILD, maintain, and operate a transportation system that is safe, reliable, and secure.

5. 5 Safety –24% of all crashes occurred on slick pavement or under adverse weather. Mobility –Travel delay can increase by 11% to 50%, depending on weather severity. Productivity –Weather-related delay can add $3.4 billion to freight costs annually. The Effects of Weather on Our Roads

6. 6 Achieving 21 st Century Operations Institutional Change –Customer focused –Performance based –Systems, not jurisdictions –Real-time information –Proactive –24/7 Technical Advancement –Information gathering –Information sharing –System mgmt. & control –Vehicle-based –Vehicle-to-vehicle –Vehicle-to-roadside-to- home base –Electronic payment

7. 7 Realizing the Vision Institutional Change Technical Advancement 21 st Century Operations A Cultural Shift

8. 8 21 st Century Operations Under All Weather Conditions FHWA is providing leadership and direction for: –Institutional Change Bridge transportation and meteorological communities Build markets –Technical Advancement Develop integrated solutions Leverage resources Developing solutions that alleviate the effects of adverse weather on the transportation system.

9. 9 Progress to Date FHWA/NOAA Partnership The Maintenance Decision Support System (MDSS) The Clarus Initiative

10. 10 FHWA/NOAA Partnership FHWA and NOAA have common strategic goals –Reducing the loss of lives on the surface transportation system. –Improving mobility to aid the free flow of commerce. Numerous examples of collaboration –A Memorandum of Understanding was signed in July 2005. –FHWA and NOAA co-chair the Working Group on Weather Information for Surface Transportation. –Cost-share on research and outreach projects.

11. 11 Maintenance Decision Support System (MDSS) The MDSS is a winter maintenance decision support system that combines: –Advanced weather prediction –Advanced road condition prediction –Rules of practice for anti-icing and de-icing The system generates winter treatment recommendations on a route-by-route basis. MDSS is a prime example of an integrated solution, enabling maintenance managers to make better, more effective decisions on when and how to deploy resources and treat roads.

14. 14 The Clarus Initiative Clarus is a system that assimilates, quality checks, and disseminates the Nation’s road weather observations. Initiative Objectives: –Design, develop and demonstrate these capabilities. –Work with our public and private partners to develop and evaluate the value-added road weather information products that Clarus enables. –Establish partnerships to move from demonstration to deployment of a nationwide network.

15. ESS owned by State Transportation Agencies An Environmental Sensor Station (ESS) is any site with sensors measuring atmospheric conditions, pavement conditions, and/or water level conditions.

16. 16 Unlimited Possibilities! Route Specific Radio & TV Broadcasts of Travel Conditions More Effective Websites Credible & Precise Travel Advice Add Detail to HAR & VMS Spawn New Technologies (in-vehicle, PDA) Clarus Enhanced decision making tools

17. 17 Establish a Road Weather R&D program: –Follow NRC report “Where the Weather Meets the Road” –Promote technology transfer –Expand research and development Multi-disciplinary stakeholder input: –NOAA –AASHTO –National Science Foundation –Private sector –Non-profit organizations Funding: $5m/yr for 4 years SAFETEA-LU – Section 5308

18. 18 Section 5308 – Road Weather R&D Program Affirms that we are on the right track. Enables us to do even more –Expand upon the success of MDSS. –Integrate Clarus and Vehicle Infrastructure Integration (VII). –Build weather-responsive traffic management tools.

19. 19 Build upon the success of MDSS by expanding it to support other operations and maintenance decisionmaking. –Weather-responsive traffic management and traveler information. –Maintenance and construction. Support the new market of MDSS services by documenting costs and benefits. Continued outreach, education, and technology transfer. Expand MDSS

20. 20 There is a strong link between Clarus and the Vehicle Infrastructure Integration Initiative (VII). The marriage of these two initiatives will: –Completely alter the road weather landscape –Spark new innovations in the private sector –Change the way that atmospheric scientists observe and model the boundary layer Over the next four years, we will tap into the VII data stream, turning it into valuable road weather observations that can be utilized by the road weather community. Integrate Clarus & VII

21. 21 Weather-responsive Traffic Management Traffic managers must be proactive. Integrated solutions pave the way. –Both transportation modeling and weather modeling are improving in resolution, focusing on the mesoscale. –Merging mesoscale weather forecasts (e.g., a precipitation forecast for the next 8 hours) with traffic models will enable a traffic manager to take action before the weather has a chance to take effect. Over the next four years we will explore such model integration as well as the development of better weather-responsive traffic management strategies.

22. 22 Conclusion Improved weather management is a key part of 21 st century operations. The FHWA Weather Management program has established the institutional relationships and demonstrated the potential of technology. SAFETEA-LU Section 5308 will serve as a catalyst to change surface transportation weather and operations: –Providing the resources to develop integrated solutions –Creating demand for these solutions by building bridges between the transportation and meteorological communities –Leveraging public sector resources to build markets and improve private sector services These efforts will ultimately change the way that we make decisions, which will save lives, time, and money.
