The purpose of this program is to reduce deaths or serious injuries in transportation-related crashes in tribal areas by supporting strategic safety planning, data collection and analysis, and the implementation of safety projects. Priority will be given to projects that incorporate safety into existing infrastructure, and successful projects will leverage resources, encourage partnerships, obtain results from strategic safety planning, and have the data to support the applicants' approach in addressing the prevention and reduction of death or serious injuries in transportation-related crashes.

Funding will be distributed via the following award categories:

  • Safety plans
  • Data assessment, improvement, and analysis activities
  • Systemic roadway departure countermeasures
  • Infrastructure improvement and other activities listed in 23 U.S.C. 148(a)(4)

Examples of eligible projects under 23 U.S.C. 148(a)(4) include:

  • Intersection safety improvements
  • Pavement and shoulder widening
  • Installation of rumble strips or other warning devices
  • Installation of a skid-resistant surface at an intersection or other location with a high frequency of crashes
  • Improvement for pedestrian or bicyclist safety or safety of persons with disabilities
  • Construction and improvement of a railway-highway grade crossing safety feature, including installation of protective devices
  • Conducting model traffic enforcement activities at railway-highway crossings
  • Construction of traffic-calming features
  • Elimination of roadside hazards
  • Installation, replacement, and other improvement of highway signage and pavement markings

Refer to pages 8-9 of the OldNOFA file for additional examples of eligible projects under 23 U.S.C. 148(a)(4).

Projects must be consistent with a transportation safety plan and must correct or improve a hazardous road location or feature or address a highway safety problem. Projects must also be identified through a data-driven process. While the focus of this program is on improving transportation safety, many projects also address community health, livability, sustainability, transportation alternatives, and climate change.

This program emphasizes:

  • Development of strategic transportation safety plans using a data-driven process as a means for tribes to determine how transportation safety needs will be addressed in tribal communities
  • Assessment and improvement of traffic records systems
