The American Association of State Highway and Transportation Officials (AASHTO) recently introduced the latest data set from its AASHTO Census Transportation Solutions technical service program or ACTS; a cooperative program funded by state departments of transportation that produces a set of special transportation-focused tabulations using large sample surveys conducted by the U.S. Census Bureau.
The data set is called Census Transportation Planning Product or CTPP and the 2017-2021 Census Transportation Planning Products (CTPP) dataset is now publicly available.
The CTPP dataset serves several critical functions in transportation planning, including:
- Creating population forecasts
- Modeling travel demand
- Analyzing population socio-demographics
- Creating vehicle ownership models
- Validating transportation forecast outputs
CTPP tabulations include three geographies: residence-based, workplace-based, and worker flows between home and work. Worker “home-to-work” travel flow information is unique to the CTPP tabulations.
