In 1991, the Federal Highway Administration (FHWA) recognized a need to expand the Local Technical Assistance Program to serve tribal nations.

The Tribal Technical Assistance Program (TTAP) is a training and technology transfer resource for Native American tribes in the United States. It is funded by the FHWA and the Bureau of Indian Affairs.

TTAP aims to:

• Distribute technical assistance and training activities at the tribal level;
• Help implement administrative procedures and new transportation technology at the tribal level;
• Provide training and assistance in transportation planning and economic development;
• Develop educational programs to encourage and motivate interest in transportation careers among Native American students.

The goals of TTAP are accomplished through technology transfer and training, research, and cultural consideration.
