CTPP 1990 and 2000 data may be accessed online from the BTS TransStats by typing "CTPP" in the search box. BTS TranStats provides the CTPP data in CSV format. Alternatively, the data can be downloaded in the CD-ROM format from the BTS bookstore by typing "CTPP" in the search box. The CD-ROM version comes with the CTPP Access Tool (CAT) which allows you to browse tables, combine cells, make simple maps and export to different file format. This requires software installation on your desktop PC.
