The Highway Safety Improvement Program (HSIP) was introduced through federal surface transportation legislation, first in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for User (SAFETEA-LU) and now identified in the Infrastructure Investment and Jobs Act (IIJA), and specifically focuses on improving road safety. The Arizona Department of Transportation (ADOT) Traffic Safety Section administers the local agency projects funded through the HSIP program. MAG previously received their own allocation of HSIP funding but starting in 2018 the State stopped allocating funding regionally and shifted to a Statewide competitive process.
