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:

b. How to use the CTPP2000 Access Tool with Part 3 (home-to-work flows)

d. How to use the BTS TranStats webpage to download files. April 2005

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.

And, lastly, but MOST importantly, please provide your feedback on
TABLEs for the NEXT CTPP.
