The following phase1 s​tudies from the ​SHRP2 Implementation Assistance Program were selected to receive additional funding to continue into phase 2. The phase 2 projects began in early 2016 and will range in duration from 16 to 30 months.

**Phase 2 has not yet been completed, so the reports included below are interim reports to serve as an early snapshot of progress as of April 2017.

FHWA STAC - Safety Training and Analysis Center

  • The Federal Highway Administration (FHWA) has established the Safety Training and Analysis Center (STAC) at Turner-Fairbank Highway Research Center (TFHRC) to assist the research community and State departments of transportation (DOTs) when using data from the second Strategic Highway Research Program’s (SHRP2) Naturalistic Driving Study (NDS) and Roadway Information Database (RID).
