RE: [CTPP] RE: TAZ software training vs. not using the TAZ software

by Elaine.Murakami＠dot.gov

Hi Mark - 1. The Census Bureau Geography Division will need a block equivalency file. Perhaps the CB geo staff can answer the question of whether the TAZ Instruction will include a FILE LAYOUT for the output files. If so, then it seems to me that you SHOULD be able to do the TAZ delineation OUTSIDE of the MTPS TAZ module software, but it would NOT be the PREFERRED method. The software has checking features, e.g. completeness, contiguity, etc, such that if you make your own file using the new TIGER files, it will not have the same quality control features. 2. What other purposes of "Census TAZs and TADs". The current CTPP is funded to include the 3-year (2006-2008) tabulation and the 5-year (2006-2010) tabulation, but depending on how things go, future 3-year and/or 5-year CTPP tabulations are possible if someone wants to pay for them. We think that the Census Bureau should have made a consistent geographic tabulation unit for the 20,000 population threshold (for the 3-year ACS), so that there could be complete coverage, instead of the "swiss cheese" coverage using counties and places, but they didn't and haven't. So, this is OUR opportunity to do something about it, and maybe we can convince the CB that these units could be an ACS 3-year tabulation geography in the future. The PUMAs (100,000 population threshold) provide a consistent geographic tabulation unit for the 1-year ACS, but how they have been defined has not always been useful to transportation planners. As you know, PUMAs were not designed to be tabulation units, but have become tabulation geographic units in the ACS. 3. No one is required to define Census TAZs. If you think that defining Census TAZs is too much work for the value you will get from CTPP, you can just say to use census tracts, or block groups for CTPP. However, we still would recommend that you define TADs, by combining tracts, for the reason listed above.

Answer: For the TAZ and TAD delineation, it is important to be able to use the TIGER files with the 2010 geography and 2010 population counts. The 2010 population counts will be released to the public on a flow basis starting in March 2011, so we have to wait until these data are available to begin TAZ and TAD delineation. If the 5-year CTPP using 2006-2010 ACS records will be tabulated for TAZs and TADs, the TAZ and TAD delineations need to be completed quickly and returned to the CB Geography Division (GEO) 3 months after the agencies receive their files (no later than July 2011). This provides GEO with sufficient time to QC the submissions, produce the necessary files so that ACS records will get TAZ/TAD identifiers, and create TIGER/Line shapefiles for TAZ/TAD geography. If the TAZs and TADs are not delineated within this time frame, the CTPP tabulation could be delayed for another year, that is, Fall 2013. Question: are there strict thresholds on either residential population or workplace population? Answer: No. The software will give a warning message, but will still allow you to define TAZs below the recommended "threshold." (The FAQ will include more discussion about this topic.) We are working on an FAQ document on TAZs and will post it on the AASHTO CTPP page. http://ctpp.transportation.org/Pages/taz.aspx <http://ctpp.transportation.org/Pages/taz.aspx> Elaine Murakami FHWA Office of Planning 206-220-4460

RE: [CTPP] RE: TAZ software training vs. not using the TAZ software

by Pete Swensson

Mark: I am on the AASHTO CTPP committee, and I can answer part of your question: You can create your own shape files, you can import them into the TAZ delineation software for viewing, BUT you cannot submit them directly to Census as your desired TAZ delineation. Census needs the delineations from all the MPOs and DOTs from across the land in a single uniform file format, which is the format of the output of the TAZ software. The software will allow you to import your shape files so that you can construct the TAZs with the shapes from your other software as a background layer.

[CTPP] TAZ Training Workshops in February

by Ed Christopher

This is a follow up to Elaine's email. Will you be responsible for creating the TAZs and/or the "new" Traffic Analysis Districts for the 5-year CTPP data in your state or MPO? Will you need to know the process or be managing a TAZ/TAD delineation effort? If the answer to any of these questions is yes, then you will certainly want to register and attend one of two repeat webinars that will be held at the end of February. --Friday, February 25, 2011, from 10 a.m. to noon EASTERN Registration Link https://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_reg.a… --Monday, February 28, 2011, from from 2 p.m. to 4 p.m. EASTERN Registration Link https://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_reg.a… The Webinars will feature a discussion of the Census Data TAZs/TADs, the delineation rules and time line. There will also be a demonstration by Census Bureau staff of the delineation software that MPOs and States will be using coupled with ample time for Q and A. The webinars will both be recorded and posted on the AASHTO CTPP website at http://ctpp.transportation.org If you are having troubling registering you can email either Elaine Murakami (Elaine.Murakami(a)dot.gov) or me and we will try to help.

[CTPP] New ACS 3-year data released

by Ed Christopher

Now that we have all had time to digest the 2010 population count and the 2005-2009 5 year ACS estimates the 3-year 2007-2009 ACS have arrived. Today the U.S Census Bureau announced the release of the 2007-2009 American Community Survey (ACS) 3-year estimates on American FactFinder. This release covers the same topics included in the previously released 2009 ACS 1-year estimates. The 2007-2009 ACS estimates have a 3-year time frame and are only available for areas with populations of 20,000 or more. You can access the newly-released data on American FactFinder at: 2007-2009 ACS 3-year data http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=ACS&_s… If you would like more information and supporting documentation for this data release please visit the ACS web site at: www.census.gov/acs [ http://www.census.gov/acs ] -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C)
