This R package provides direct access to the latest Census Transportation Planning Products (CTPP) datasets. The estimates provided in CTPP tables are some of the only sources available from large-sample survey data that are related to transportation behavior. Learn more about the CTPP and the types of tables available by browsing here and here.

The download function works with two datasets, and our ability to fetch their tables from R depends on the following pages:

2006-2010 5-Year CTPP

2012-2016 5-Year CTPP

Reference the install readme for specific instructions. Most use RStudio Desktop to develop analyses with R.
