NHTSA - Behavioral Safety Research

rosaP Repository & Open Science Access Portal

This collection includes reports from the National Highway Traffic Safety Administration (NHTSA) Behavioral Safety Research program. For the program, NHTSA studies behaviors and attitudes in highway safety, focusing on drivers, passengers, pedestrians, and motorcyclists. NHTSA identifies and measures behaviors involved in crashes or associated with injuries, and develop and refine countermeasures to deter unsafe behaviors and promote safe alternatives.
More information on the program can be found at https://www.nhtsa.gov/behavioral-research. Bookmark this collection: https://rosap.ntl.bts.gov/collection_nhtsa_bsr or https://doi.org/10.21949/1530843.

    2010-04-01 | NHTSA BSR Traffic Tech | PDF
    Relating behind-the-wheel driving performance to performance on office-based screening tools is challenging. It is important to use tools that are predictive of poor driving performance (sensitivity), but also to find tools that do not have high proportions of false positives (specificity). This project explored both. Driving equates to independenc ...
