  7. Enter the ACS era… 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 CTPP as a place to look for Census Data products to help with your Transportation needs
