Transportation Planning

As defined in 25 CFR Part 170.400 and 410, the purpose of transportation planning is to "clearly demonstrate a Tribe's transportation needs and to fulfill tribal goals by developing strategies to meet transportation needs. These strategies address current and future land use, economic development, traffic demand, public safety, health, and social needs." The long-range transportation plan development process allows for the inventory and analysis of infrastructure often in collaboration with State, Regional Planning Organizations, Cities, Counties, and other stakeholders to identify projects to improve multi-modal transportation options locally and regionally. As such, and as referenced in 170.414, developing a long-range transportation plan (LRTP) is crucial in the formulation of a comprehensive tribal priority list or Tribal Transportation Improvement Program (TTIP) as a planning tool to program and deliver projects to meet the identified needs and for inclusion in the State Transportation Improvement Program (STIP).
