The Federal Highway Administration (FHWA) established the Highway Safety Improvement Program (HSIP) to achieve a significant reduction in traffic fatalities and serious injuries on all public roads.The HSIP emphasizes a data-driven, strategic approach to improving highway safety that focuses on results.Under the enabling transportation legislation enacted in December 2015, Fixing America's Surface Transportation (FAST), New Jersey receives approximately $57 million annually for safety improvements.”The HSIP requires a statewide strategic highway safety plan to set goals and prioritize safety investments. The HSIP also requires annual progress reporting to the FHWA.Data source and extract/transform script - https://github.com/dvrpc/planning-data-management/tree/main/gis-hsip
