Each year, the American Association of State Highway and Transportation Officials (AASHTO) honors the best transportation research projects with High Value Research (HVR) awards. Supplemental HVR Awards are also given for research conducted on topics of special interest.
This year, Iowa’s efforts to train and improve computer models to predict where salt or other treatments should be applied during winter weather to make roads safer was selected for the supplemental award by the agency’s eight peers in AASHTO Region 3: Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Ohio, and Wisconsin.
Like other states, Iowa uses a mix of stationary and mobile sensors along the state’s highways to measure road friction and guide its winter maintenance activities. This research used friction models to accurately estimate where treatments are needed even in locations of the state where sensors aren’t available.
This award marks the 13th HVR award (including supplemental HVR awards) that Iowa DOT Research has earned in the last 10 years.
AASHTO’s Research Advisory Committee will recognize all 2023 winners during its summer meeting in July. Winners will also participate in a poster session dedicated to high-value research projects at the annual meeting of the Transportation Research Board in Washington, DC in January 2024.
