Hello,
I was also able to download the Part 1, 2 and 3 files. The 217,282 by 217,282 matrix of
Part 3 TAZ info is a bit slow to work with on standard computers operating in 32-bit
(which is why preparation of subsets and/or special aggregations is indeed a good idea for
specific analysis purposes), but this is nevertheless rather impressive when one considers
the number of individual TAZ-to-TAZ cells in the matrix: 47 billion! Fortunately, the
130 million expanded "trips" (i.e., workers age 16+ for all modes, including
"worked at home" and "other method") is spread across a much more
manageable 6.2 million cells.

Hi Peter:
Thanks for informing.
When logging in our user account, I haven't found any post/download link for 5-yr
CTPP. In addition, the latest post we see in the use center is from Dec 2013.

All:
Caliper Corporation is pleased to announce the availability of the Census Transportation
Planning Package (CTPP) data for Parts 1, 2 and 3 on its User Center for download. Caliper
has processed the most recent estimates of the CTPP data for the most commonly utilized
tables from the latest American Community Survey (ACS) and is making the three part series
available to all TransCAD users with current support agreements. For Parts 1 and 2 the
data is in the TransCAD Fixed Format Binary table format, while the Part 3 data is in
TransCAD matrix format. The data extents are nationwide, including the TAZ to TAZ
journey-to-work flows, a matrix of 217,282 rows and columns with 58 sub-matrices. For the
journey-to-work matrices of flows for the Means 7 tabulation, margins of error for each
Origin-Destination pair are included as separate matrix files. Users can easily make
subsets of the data to suit their needs for their regions using the standard tool set in
TransCAD.
Users can access the Caliper User Center from our website by clicking on the following
