Enter the ACS era… Census Transportation Planning Products The CTPP embodies a collection of 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 Addedproducts. The CTPP captures all of these. Think of CTPP as a place to look for Census Data products to help with your Transportation needs
