who we are

CTRE's front door

CTRE is located in the Iowa State University Research Park, which is easily accessible from US Highway 30.

CTRE researchers create new knowledge and practical tools for transportation professionals. CTRE’s safety research runs the gamut from work zones to safer roadway designs to tools for analyzing crash data. Researchers investigate issues such as energy efficiency and air quality. They also create asset management tools for pavement marking, signs, and bridges for the Iowa Department of Transportation (Iowa DOT).

CTRE traces its roots to 1983 when it was established as one of the Federal Highway Administration's 10 original Rural Technical Assistance Programs (now Local Technical Assistance Programs). See a brief history of CTRE.
