FHWA asked National Academies to identify research needed to address

FHWA asked National Academies to identify research needed to address
weather impacts on the road environment
Weather impairs both safety and efficiency of roadways
– Associated with over 1.5 million accidents annually, accounting for ~600,000 injuries and 7,000 deaths
– Associated with 500 million hours of driver delay annually
Few new roads and increasing vehicle miles traveled will exacerbate already existing capacity problems

The Road Weather SystemOf The Future
The Road Weather SystemOf The Future
• “Infostructure” overlaying Road Infrastructure– Measurements to monitor weather, road conditions, and traffic flow– Integrated model-based decision support tools– Telecommunications tools to move data to/from the roadway– Multi-purpose components serving drivers, traffic managers, law
enforcement, emergency management, road maintenance
• “Smart” Vehicles– Communication with the road infostructure and other vehicles– Advise drivers on options, road and traffic conditions, safety concerns– Mobile observing platforms
• “Weather-smart” Users– Training and education programs required

Program Goals:
• Maximize use of available road weather information and technologies;
• Expand road weather research and development efforts to enhance roadway safety, capacity, and efficiency while minimizing environmental impacts; and
• Effectively implement new scientific and technological advances
Primary Recommendation:
Establish a focused, coordinated national road weather research program
![Page 5: Board on Atmospheric Sciences and Climate Transportation Research Board Where the Weather Meets the Road: A Research Agenda for Improving Road Weather](https://reader035.vdocuments.site/reader035/viewer/2022062517/56649e7f5503460f94b83c24/html5/thumbnails/5.jpg)
Program Implementation
Regional Road Weather Research Centers• To develop new technologies, foster technology implementation
on regional roadways, and facilitate interaction between governments, the private sector, and academia
• Should bring together weather and transportation researchers, and practitioners/service providers in the public and private sectors
National Demonstration Corridors• To demonstrate effectiveness of road weather improvements,
facilitate nationwide implementation of research results, and provide a seamless stream of road weather information to users

Centralized leadership at the federal level is essential
• FHWA should have lead role in new road weather research program
– NOAA should be leading partner– Federal government should establish new interagency coordinating council to
guide program with participation from FHWA, NOAA, and NSF at a minimum
• New long-term dedicated funding within FHWA is needed– ~$25 million per year– Funds from other relevant initiatives should be highly leveraged
• Must foster effective public-private-academic partnerships– Essential partners include FHWA, NOAA, NSF, AASHTO, academia, state
and local governments, the private sector, and NGOs such as ITS America and AMS
