Dear Everyone – Change is a good thing, and
Nandu’s departure to a new job is an opportunity to re-think how we
provide information to people.
Basically, the CTPP2000 data are available in 2
formats: The CDs ordered from the BTS Bookstore include software
called the CTPP2000 Access Tool (https://www.bts.gov/pdc/index.xml)
and downloading from the BTS TranStats webpage. http://www.transtats.bts.gov/
You can select “highway” on the left column and then find
CTPP2000 files. They are available as flat ASCII files, or as CSV
files.
Here are some useful links:
1. CTPP Training page http://www.fhwa.dot.gov/ctpp/training.htm
2. Several articles from the CTPP Status Report (http://www.fhwa.dot.gov/ctpp/status.htm)
include help with CTPP Data access:
a. Organizing your files to use the CTPP2000 Access
Tool. January 2005, by Ed Christopher
b. How to use the CTPP2000 Access Tool with Part 3
(home-to-work flows) April 2005, by Clara Reschovsky
c. Accessing CTPP Part 2 data from the
d. How to use the BTS TranStats webpage to download
files. April 2005 issue, article by Nanda Srinivasan
Also, sometime (after Nandu’s replacement is
available, which I hope is in January), I would like to compile the many
examples of applications of using the CTPP data for transportation and other
planning activities that are currently spread out across the CTPP Status
report. There is now an INDEX of articles in the Status Report http://www.fhwa.dot.gov/ctpp/srindex.htm
—it isn’t great, but it’s a start.
Also, I am hoping we will have a significant updating to the
CTPP webpage in the near future. http://www.fhwa.dot.gov/ctpp/index.htm
And, lastly, but MOST importantly, please provide your
feedback on TABLEs for the NEXT CTPP. http://trbcensus.com/acs/tables.html
