Highway Safety Improvement Program (HSIP)

Federal Agency


Federal Highway Administration (FHA)


To reduce traffic fatalities and serious injuries on all public roads, including non-State-owned public roads and roads on tribal lands. The program requires a data-driven, strategic approach to improving highway safety on all public roads that focuses on performance.

Applicant and/or Project Eligibility Requirements

Funds are distributed to each state. Funded projects must be consistent with the State's strategic highway safety plan (SHSP). Most eligible activities are infrastructure-safety related. Up to 10% of funding can be used to fund certain non-infrastructure activities and behavioral safety projects, such as educational campaigns about traffic safety and enforcement activities.

Decarbonization Considerations

While this program will fund safety projects generally, applicants should prioritize projects that will decrease the need for private vehicles on the road and increase transit ridership, promote carpooling and ridesharing, and be in coordination with regional transit-oriented development planning. Communities should look to deploy extensive, convenient, well-connected bus rapid transit projects that can align with local, regional, and statewide vehicle electrification plans.

Equity Considerations

In order to effectively and equitably improve road safety, understand which communities lack reasonable and convenient access to transit and multi-modal options. This could include additional collaboration with frontline communities and other stakeholders to address both procedural and distributional equity concerns.
