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.
