What Is Happening During Safety Data Phase 1?
Phase 1 of SHRP 2 Safety Data Implementation and Oversight is the initial post-data collection phase of the second Strategic Highway Research Program (SHRP 2) Safety Study. The study, completed in 2015, collected an unprecedented amount of objective data on driver behavior and the driving context. The SHRP 2 Naturalistic Driving Study (NDS) captured detailed data on 3,500+ volunteer passenger-vehicle drivers, including continuous driving data and video of the road and the driver over 35 million vehicle miles and more than 4,200 crashes and near-crashes. The SHRP 2 Roadway Information Database (RID) collected detailed roadway data on 12,500 centerline miles, compiled existing driving context data on another 200,000 centerline miles, and made it possible to link the roadway data to the driving data. Together, the Naturalistic Driving Study and the Roadway Information Database are the “SHRP 2 Safety Data.”
Phase 1 is an experimental program designed to make the Safety Data widely available to qualified researchers and to gather information needed to support decisions about implementation and oversight of the data beyond the first five years.
Phase 1 of SHRP 2 Safety Data is administered by the Transportation Research Board (TRB) and is sponsored by the Federal Highway Administration (FHWA) in association with the American Association of State Highway and Transportation Organizations (AASHTO), the National Highway Traffic Safety Administration (NHTSA).
