The Census Transportation Planning Products (CTPP) is a program of custom tabulations and data products for the transportation community from the US Census Bureau American Community Survey (ACS). ACS, which replaced the decennial census long form, requires accumulation over multiple years for tabulation. CTPP includes training, technical assistance and research.

The CTPP is sponsored by FHWA and AASHTO Inter Agency Agreement with the US Census Bureau (CB). AASHTO consolidated the national CTPP fund to purchase all CTPP related activities.
