Joe,
See below. I could create TADs about 36 to approximate the traffic
districts database we already have. This work would probably take 3 hours
or so. Sample data at this geography would be more statistically
significant than TAZ, or even municipal geography.

Subject: [CTPP] TAZ delineation update
Over 100 agencies have ALREADY submitted their files to the Census Bureau
Geography Division, with at least 10 agencies submitting files today (June
16).
The CB GEO staff have found that the TAZ files look pretty good, and
although there are some TAZs that look "too small" these are often in areas
with parks or water areas. They also said that the TADs look VERY good,
with very good adherence to the 20,000 population threshold.
Thank you to everyone! I know the rest of you who are participating in the
program are working very hard to complete this task. Getting the TAZ and
TAD into Census TIGER is one step for the CTPP 5-year tabulation. This
tabulation will use ACS records from 2006-2010. AASHTO is expected to
submit the 5-year table list to the Census Bureau's Disclosure Review Board
this July.
