[CTPP] TAZ delineation training session from February 25.

Hi Everyone - some of you are NOT involved in TAZ delineation, so you can just DELETE this email! But, in case you are involved, and were not able to attend the webinars that we held on 2/25 and 2/28, here is a link to the recorded session. http://fhwa.adobeconnect.com/p11971019/ <http://fhwa.adobeconnect.com/p11971019/> This session will be archived and posted on the AASHTO CTPP webpage TAZ area: http://ctpp.transportation.org/Pages/taz.aspx in the near future, as it will not live on the FHWA NHI site for very long. The Census Bureau Geography Division expects the TAZ software to be final by March 16, but the geographic files for all of the nation may not be available at that time, which is why the term "rolling" release has been used. Since the Census Bureau Geography Division says that the 90-day turn-around time is FIRM, you will need to start working on this ASAP! But please note, TAZ delineation is not mandatory for CTPP. You can use census tracts (default) or census block groups as your small tabulation geography for CTPP. We will update the FAQs for TAZ delineation (currently posted on both the AASHTO page and the FHWA page http://www.fhwa.dot.gov/ctpp/tazfaq.htm ) based on the questions and answers from the sessions held on 2/25 and 2/28. If you are interested in using 2010 Census Block Equivalency Files as a starting point, the instructions are posted on the FHWA page: http://www.fhwa.dot.gov/ctpp/tazmtps.htm Elaine Murakami FHWA Office of Planning 206-220-4460
