Census Transportation Planning Products
The CTPP embodies a collection of Census Data
used for Transportation Planning. With changing
data needs and the ACS, there will be a variety
of different products useful for transportation
planning emanating from Census Data. There will
be Special Tabulations, Standard Tables and even
Value Added-products. The CTPP captures all of
these.
Think of the CTPP as a place to look for Census
Data products to help with your Transportation
Planning needs
