NHTSA - Behavioral Safety Research

rosaP Repository & Open Science Access Portal

This collection features publications and reports from the National Highway Traffic Safety Administration's (NHTSA) Behavioral Safety Research program. The program studies highway safety attitudes and behaviors, with a specific focus on the actions of drivers, passengers, pedestrians, and motorcyclists. Resources in this collection help identify and measure the human behaviors most frequently involved in crashes or associated with traffic injuries. Furthermore, these reports document the development and refinement of safety countermeasures designed to deter unsafe practices and promote safe transportation alternatives. For more information, visit the NHTSA Behavioral Research page.
