The Highway Safety Improvement Program (HSIP) goal is to achieve a significant reduction in traffic fatalities and serious injuries on all public roads through the implementation of infrastructure-related highway safety improvements. The Fixing America's Surface Transportation (FAST) Act continues and refines the HSIP.
Detailed provisions pertaining to the HSIP, such as qualifying projects and federal funding share, are defined in Section 148 of Title 23, United States Code (23 USC 148).
To ensure that application of the HSIP is organized and systematic providing the greatest benefits to safety, the Federal Highway Administration (FHWA) has established a formalized HSIP process that consists of three major components: planning, implementation and evaluation. These requirements are contained in Part 924, Title 23 Code of Federal Regulations (23 CFR 924).
