AED20(1): Call for Posters 2025

by Kyla Elzinga

Hi CTPP listserv - The AED20(1) Subcommittee announces its Call for Posters for the 2025 TRB Annual Meeting. We look forward to your submissions. Call Title Understanding Census Data through Visualization Sponsoring Committee Census Data for Transportation Planning Subcommittee of the Urban Transportation Data and Information Systems Committee, AED20(1) Call Description The Census Data for Transportation Planning Subcommittee of the Urban Transportation Data and Information Systems Committee, AED20(1), invites you to submit posters for a session focusing on Understanding Census Data through Visualization. In keeping with the theme of our parent committee, topics focusing on transportation planning and urban data are requested. Posters will be displayed at the TRB Annual Meeting in Washington, DC, January 2025. All accepted posters will also have their work displayed on the AED20(1) website. Authors of the most innovative poster may be invited to present at the subcommittee meeting. Background The Subcommittee is interested in seeing the innovative ways in which people are visualizing the Census to gain a better understanding of the demographic data. Do you have a new graphical or visual way to display traditional data to aid in analysis? Have you found a new platform to display the data? Have you been using a new method to illustrate complex statistical concepts? How can viewing the Census data in a new way help in analyzing the data? Have you run into issues or limits in using newer methods? The goal of this poster session is to highlight new and creative ways to visualize Census data. The poster session would also like to share any challenges and lessons learned from translating complex Census data into visual and analytical products. Evaluation Criteria Posters must incorporate data from at least one Census data product; Census data products include but are not limited to Decennial Census data, the American Community Survey, LEHD, Economic Census data, and AASHTO Census Transportation Solutions (ACTS, formerly CTPP). Additional non-Census data sets may be used. Note: The National Household Travel Survey (NHTS) is not a Census data product. A broad range of abstracts relating to Understanding Census Data through Visualization are welcome. Preference will be given to posters which emphasize the following: * Analysis to solve complex problems; * Creative ways to visualize Census data; * New approaches to analyzing Census data; * Demographic data to improve transportation planning; and/or * Topics that address applications towards urban areas. A session-development panel will review all abstracts to identify those that most effectively meet the goals of the poster session. The subcommittee hopes to identify posters representing a diverse array of uses and applications. Applicants will be notified in late September whether their submission has been selected. Poster Session Guidelines Those selected for this session will prepare a poster for presentation at the 2025 Annual Meeting in January. Participants are not required to prepare a paper. Each presenter will be provided with a table and a 4' x 8' vertical panel for displaying posters and other materials. An electrical connection will be available at each station. Telephone and internet connections will not be available. TRB's guidelines for poster presenters are not yet available, but it is expected that all guidelines once available should be followed. Presenters are expected to register for the TRB meeting and participate in this session. Presentation teams are welcome. Submission Instructions A special deadline for submittals has been established. Interested candidates should submit an abstract explaining their project and poster concept by 11:59 pm EDT on Monday, September 16, 2024. The abstract should be no more than a single one-sided page in length (approximately 500 words) and include: * Main Contact information (name, agency/organization, phone number, email address) * List of all authors of the poster including each person's name, agency/organization, and email address * Title of your proposed poster for use in the Annual Meeting agenda * Data sources that your poster will focus on * Explanation of the project, research, or process sets * Any innovative discoveries or lessons learned that would be useful to the transportation community * Preliminary description of the information to be conveyed in your poster In addition to the abstract, you are encouraged to include up to two visual(s) to demonstrate your poster concept. You are also welcome to include links to on-line materials that illustrate the analysis or results described in your abstract, but this will not substitute for the information requested in the abstract. The subcommittee will not consider sales presentations for products or services. Abstracts should be in a PDF format and submitted to: Kathy Yu kyu(a)nctcog.org<mailto:kyu@nctcog.org> Include the term "AED20(1) Poster Abstract 2025" in the subject line. For More Information Questions about the poster session or the abstract submittal process should be directed to Kyla Elzinga kelzinga(a)aashto.org<mailto:kelzinga@aashto.org> 202-624-7797 Kathy Yu kyu(a)nctcog.org<mailto:kyu@nctcog.org> 817-608-2343 Kyla Elzinga she/her Program Manager for Planning and Data AASHTO | American Association of State Highway and Transportation Officials (202) 624-7797 | kelzinga(a)aashto.org<mailto:kelzinga@aashto.org>

Re: [TMIP] Comparison of CTPP OD flows at different aggregation levels?

by Charles Purvis

Hey Jim: Krishnan and Ed are correct and on target. The 2012-2016 and forthcoming 2017-2021 CTPP do NOT include the “extended workplace allocation”. Previous packages (1990?, 2000, and 2006/2010) DID have extended workplace allocation. Allocation is the Census Bureau term for missing value imputation. “Standard Workplace Allocation” is Census-speak for “primary imputation”. This process imputes workplace location down to the county, place and MCD level. (Imputation down to MCD-level is evident in “strong MCD” states such as Vermont. Vermont has 255 MCDs, and 184 Census Tracts!) The standard allocation is needed for the Census Bureau to provide county-to-county commute patterns to OMB for purposes of defining metropolitan areas. “Extended Workplace Allocation” is “secondary imputation” down to the TAZ, TAD and Tract levels. My recommendation: Factor up the 2012-2016 CTPP commuter flows (TAZ-to-TAZ, TAD-to-TAD, tract-to-tract) to match county-to-county-by-mode control totals. Compare commute length frequency distributions before and after this “grossing up” process. It’s an in-elegant imputation procedure. Also, use household travel survey data on home-based-work trips per worker (or home-work-home tours per worker, in activity models) to factor up workers to “observed home-based work trips” or “observed home-work-home tours”. Normalize the 2012-2016 data to a single year estimate, say, 2013 or 2014 or 2015. Use published single-year ACS data on workers by county-of-residence, county-of-work, and intra-county workers. Use the single-year ACS PUMS data for inter-county commute controls. An alternative to normalizing to a particular year, say, 2014, would be to use the single-year ACS PUMS at the PUMA of residence to PUMA of work (POWPUMA). Since POWPUMAs are always counties, the result would be a somewhat rectangular commute matrix of PUMAs-to-counties (by means of transportation). Unless you have really small counties (<100,000 population) which muddies up the analysis. In my ideal world, you’d somehow have your population microsimulation software create a base year (say, 2014) commuter matrix at a very detailed geographic level, that is somehow “trained” by data from the CTPP, published ACS data, and PUMS. And somewhere along the line it would be useful to integrate the Census Bureau’s LEHD data into the jumble. I would recommend the statistical software package “R” for census data analyses, including the packages tidycensus, lehdr, and ctppr (hopefully we’ll see a ctppr package that will handle the new 2017-21 CTPP). I would recommend the iPUMS (eh-PUMS) site to retrieve PUMS data. And the iPUMS project “NHGIS” for retrieving older, pre-2000 census data. Actually, I’d recommend trying out the tidycensus for PUMS data, as well. That’s about all I have for now.

The difference between the TADs and TAZs is more likely due to the CTPP special rounding rules and aggregating rounded values. The fix can be easy, just ID missing workers and allocate them based on best information available. How one chooses to do the allocation is the fun part since it comes down to how hard do you need to justify what you did. Being DC, I would suspect some geographic response concerns. The last work I have seen where someone looked at the distribution of the losses was the folks at the NY City Planning Department when the data first came out. > > > On 5/15/2024 2:37 PM, Krishnan Viswanathan wrote: >> This is due to the workplace allocation issue in Census data. Standard workplace allocation procedures at the Census Bureau imputes only at the county and place level geographies & not below that. In previous iterations of the ACS based CTPP, the Census Bureau did an extended workplace allocation to overcome this difference but did not do so in the 2012-2016 CTPP.
