325th International Conference on IIPS, AMS Annual Meeting, Phoenix, AZ
The Road Weather Problem• Safety
– 1.57± million weather-related crashes/year• 7,400 fatalities; 690,000 injuries
– 24% of all crashes occurred on slick pavement or under adverse weather
• Mobility: Cost of congestion is $9.45 billion/yr for the 85 major urban areas (causes ~25% of non-recurrent delay on freeways)
• Productivity: Weather-related delay adds $3.4 billion to freight costs annually
• Environment: Chemicals effect watersheds, air quality and infrastructure
425th International Conference on IIPS, AMS Annual Meeting, Phoenix, AZ
Congressional Direction – 5308• Establish a Road Weather R&D program:
– Follow NRC report, Where the Weather Meets the Road
– Promote Technology Transfer– Expand Research & Development
• Multi-disciplinary stakeholder input:– Natl. Oceanic & Atmospheric Administration (NOAA)– National Science Foundation– AASHTO– Private sector– Non-profit organizations
• Funding: $5 million/yr for 4 years

Using the new Self-Evaluation & Planning Guide:
• TMC team evaluates their needs and opportunities for enhanced weather integration– Identify weather conditions– Understand weather impacts– Identify TMC needs for weather information
• The software sorts through the information provided by the TMC and identifies potential integration strategies
• The team then develops a practical plan to implement those integration strategies
Integrating Road Weather Into TMCs
