Transportation fatalities and injuries severely impact the quality of life in Indian country. Each year under the Bipartisan Infrastructure Law (BIL), as enacted by the Infrastructure Investment and Jobs Act (Public Law 117-58), 4% of the available TTP funds are set aside to address transportation safety issues identified by federally recognized Indian tribes through a competitive, discretionary program. Projects are chosen whose outcomes will reduce fatal and serious injuries in transportation related incidents, such as motor vehicle crashes.

FHWA advocates the development of strategic transportation safety plans as a means for tribes to determine how transportation safety needs will be addressed in and around tribal communities. See additional information on developing transportation safety plans.

Eligible projects for the TTP Safety Fund include:

• develop and update transportation safety plans
• safety data assessment, improvement, and analysis
  • standardized risk-based safety assessment (also known as systemic safety study)
  • road safety audit
  • assessment and improvement of traffic records, including implementation of the Tribal Crash Reporting Toolkit
  • other safety studies
• systemic roadway departure countermeasures
  • streamlined application process for these countermeasures that address roadway departure:
    • horizontal alignment warning signs
    • delineators
    • center line and edge line markings
    • rumble strips
    • mitigation of roadside hazards (includes fixed object removal, crashworthy devices, and guardrail or other barriers)
• infrastructure improvements and other eligible activities as listed in 23 U.S.C. 148(a)(4)
  • For most projects to improve infrastructure safety. Examples include:
    • converting an intersection to a roundabout
    • roadway improvements that provide separation between pedestrians and motor vehicles or between bicyclists and motor vehicles, including medians, pedestrian crossing islands, protected bike lanes, and protected intersection features
    • flattening roadside slopes
    • reconstructing a horizontal curve
    • installation of a skid-resistant surface at an intersection or other location with a high frequency of crashes
    • improving intersection sight distance
    • and other infrastructure improvements that reduce the risk of serious injury crashes.

Safe Streets and Roads for All Program

The Safe Streets and Roads for All (SS4A), Tribal Transportation Program (TTP), and Tribal Transportation Program Safety Fund (TTPSF) are three complementary USDOT programs that are available to Tribes for projects that reduce fatalities and injuries on roadway facilities. A comparison of these programs and guidance on frequently asked questions about funding a project using grants from multiple of these sources is available here. Additional detail can be found in the applicable Notices of Funding Opportunities (NOFO).
