TAZ delineation software: update on process

by Elaine.Murakami＠dot.gov

To State DOTs and MPOs who will be delineating TAZs and TADs for the CTPP: Many of you have been sending corrections to the TAZ contact databases over the last couple of weeks. Thanks so much for your attention to this matter. If you haven't done so already, please convey your changes/updates to Ms Liang Long, liang.long(a)dot.gov The Census Bureau Geography Division has told us that they are likely to use a data download system to transmit the TAZ delineation software and the county files to you. This system will be password protected. There will still be some agencies for which this approach may not be feasible, and in those cases, a mailout will be used instead. Don't forget the workshop on ACS data at TRB annual meeting, on Sunday, January 23 at the Hilton, Columbia Hall 6 from 9:00 a.m. - noon. Hope to see you there.

ACS 2005-09 comparisons with 2000 SF3

by Elaine.Murakami＠dot.gov

Nathan Erlbaum of NY State DOT has provided some links that may help you when the first small area data are released from the ACS (2005-2009). Note: the smallest geographic unit will be census tract (2000 geography). Block Group data will be released later in Summary File format. From: Erlbaum, Nathan (DOT) [mailto:nerlbaum@dot.state.ny.us] Sent: Tuesday, December 07, 2010 5:01 AM Subject: FW: ACS 2005-09 comparisons with 2000 SF3 FYI. This may help next week when the 5-year ACS data are released. It appears that the Census Bureau has updated its guidelines for comparing the 5-year 2005-09 ACS data to 2000 data. When I checked this link today (http://www.census.gov/acs/www/guidance_for_data_users/comparing_2009/), I noticed that it included the 5-year data, which had been missing when I last checked just a week or so ago. Also, the Bureau provides a variable-specific drill-down tool here: http://www.census.gov/acs/www/guidance_for_data_users/2009_table_comparison… Pretty neat.

Developing Transportation Data Products from the American Community Survey That Comply With Disclosure Rules -- Call for Second Phase Research Test Sites

by Roisman, Richard

Dear Colleagues (apologies for cross-posting for those who also subscribe to TMIP-L), The study team for NCHRP 8-79 (Developing Transportation Data Products from the American Community Survey That Comply With Disclosure Rules) is looking for small and medium-sized MPOs to participate in the second phase of research into the impact of disclosure-avoidance techniques on the resulting data usability for transportation planning and travel demand modeling of the 5-year ACS-based CTPP tabulations. The team is interested both in small and medium-sized MPOs who maintain their own travel demand forecasting models, and MPOs who perform sketch-planning modeling using the methods from NCHRP Report 365. Participation would include production of a nominal amount of travel model output. Please contact me off-list at rroisman(a)vhb.com<mailto:rroisman@vhb.com> if you represent a small or medium-sized MPO and would like to assist the research effort, or know of some good candidate agencies.

Enhanced 2009 NHTS data (Version2)

by Elaine.Murakami＠dot.gov

Hi Everyone - at the risk of redundant postings, I am forwarding notice that the new and improved 2009 NHTS dataset has been released and is available at the ORNL webpage listed below. Last week (Dec 1-2) there was a server crash, which prevented people from accessing the new data, but things are working more smoothly today (I tested it). I highly recommend using the user-friendly on-line table generator for simple analyses. It will automatically use the correct weights. You can start with a "frequently asked for" table, click on the "wrench" symbol, and then modify the table, e.g. to subset for a specific geographic area. For example, by clicking on variable descriptors and values, the software will create code such as HHSTATE EQ "FL" to limit the table to only records in Florida. Have fun! For additional information about the NHTS, please contact Adella Santos, the NHTS Program Manager Adella.santos(a)dot.gov Elaine Murakami FHWA Office of Planning From: National Household Travel Survey [mailto:nhts@email.ornl.gov] Sent: Wednesday, December 01, 2010 7:02 AM To: nhts(a)email.ornl.gov Subject: [NHTS] Enhanced 2009 NHTS data (Version2) The Federal Highway Administration is pleased to announce the availability of the enhanced 2009 NHTS data (Version2) for the transportation community and the public. For the last 6 months, the enhancement team has worked with all partners and all involved to deliver this enhanced version of data for both national coverage and add-on localities. The enhancement of the original V1.0 data was centered on methods of processing outliers; and at the same time, FHWA capitalized on the opportunity to use the 2008 ACS for population totals which was not available during the preparation of Version 1.0. The V2.0 data file is now available on the Online Analysis Tool for your use and to download (http://nhts.ornl.gov/ ). In the following weeks FHWA will also append the Nielsen's Claritas neighborhood characteristics data and the fuel consumption (MPG) data from the Energy Information Administration as an added value to V2.0. The Code Book browser and the User Guide will be updated and available by early December.

FW: Survey on Transportation and Land Use Modeling Tools

by Weinberger, Penelope

Hi All, Below is a request from Matt Hardy, Program Director of Planning and Policy at AASHTO. If you are so inclined please answer his survey. Thanks! Penelope Weinberger CTPP Program Manager AASHTO 202-624-3556 http://ctpp.transportation.org/Pages/default.aspx <http://ctpp.transportation.org/Pages/default.aspx> It's just as bad to not make a plan as to blindly follow the one you already have. From: Hardy, Matthew Sent: Tuesday, November 23, 2010 10:07 AM To: Subject: Survey on Transportation and Land Use Modeling Tools Hello I am pursuing a PhD in the School of Public Policy at George Mason University where I am currently finishing my dissertation work. The topic of my dissertation is how simplified integrated transportation and land use modeling tools can be used to support transportation and land use planning. As part of my research, I put together a survey to better assess what role integrated transportation and land use modeling (ITLUM) tools can play in the metropolitan planning decision-making process. Recent surveys indicate that many states, jurisdictions, and metropolitan planning organizations are looking at implementing ITLUM tools. However, there are a number of ITLUM tools available to practitioners ranging from simple sketch planning tools to complex microscopic simulation tools. There are benefits and limitations to using any type of ITLUM tool. Selecting a specific tool to use is often a tradeoff among many different factors. The purpose of this survey is to gather expert opinion on the use and application of ITLUM tools as it relates to the metropolitan planning decision-making process. You can access the survey here: https://vovici.com/wsb.dll/s/54c9g4817b. Please complete the survey by January 11, 2011. If you could forward this survey to your colleagues I would appreciate it. I am trying to get as diverse a response rate as possible. I believe the topic of my research will be of interest to SCOP members and I look forward to sharing the results of my research with you. Thank you. --Matt _____________________ Matthew H.

While you are waiting for the CTPP full data release.......

by Liang.Long＠dot.gov

While you are still waiting for the CTPP full data release with the access software (scheduled on December, 2010), don't forget FHWA prepared and released the county-to-county and place-to-place flow tables prior to full data's formal release. The flow tables are for Total Workers and for 18 categories of Workers by Means of Transportation. County level data also included CTPP 2000 data but categorized only by 8 transportation modes. We have NOT included the CTPP2000 for Place-to-Place data files because of difficulties in matching FIPS codes for Places between 2000 and the current CTPP. These two files are published in CS FTP sites: ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/ Also, transportation profiles using ACS 2005-2007 and CTPP2000, which give people a quick transportation snapshot of their areas are also published at AASHTO CTPP website. http://download.ctpp.transportation.org/profiles_2005-2007/ctpp_profiles .html Liang Long Federal Highway Administration Room 74-440 1200 New Jersey, SE Washington, DC 20590 tel 202 366 6971 fax 202 493 2198 e-mail liang.long(a)dot.gov <mailto:liang.long@dot.gov>

2009 ACS 1-year data

by Elaine.Murakami＠dot.gov

The Census Bureau released the 2009 ACS (1 year) data in late September. http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=ACS &_submenuId=&_lang=en&_ts= This is the first time that sub-county (Place) totals were added to the weighting procedure. Therefore, you may see some large differences between 2008 and 2009 ACS 1-year results, based on this new method. (The previous weighting method was restricted to county level data.) I attended the Washington State Data Center meeting on Nov 5, and the CB reported that there were large differences in Detroit and Omaha, for example. We have previously reported that the lack of sub-county estimates was problematic for some cities. Please see our CTPP profile sheets using 2005-2007 ACS http://ctpp.transportation.org/Pages/profiles.aspx where we recommended that you might want to use independent city totals as controls. So, we hope that that use of sub-county controls will help the ACS in the long run, but in the short run, it is probably not a good idea to make a year-to-year comparisons with 2008 and 2009 ACS 1-year results. In general, my recommendation is to use 3-year ACS tabulations when possible, because of the increased number of unweighted survey responses. Other news: The CTPP (using 2006-2008 ACS) will be going into software beta-test this week. This round of CTPP, with more than 200 tables, will use a web-based data access system. The tabulations are restricted to geographic units with more than 20,000 residential population. Selected home-to-work flow tables (county-to-county and place-to-place) are available on the Cambridge Systematics ftp site: ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/ <ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/> Elaine Murakami FHWA Office of Planning 206-220-4460
