[CTPP] 2012 - 2016 CTPP Tab is released

by Weinberger Penelope

Dear CTPP Community I am delighted to announce that the newest CTPP dataset is live at: http://data5.ctpp.transportation.org/ctpp1216<http://data5.ctpp.transportation.org/ctpp1216/Browse/browsetables.aspx> Please head on over, do some analysis, check out your data and report any problems back to me: pweinberger(a)aashto.org<mailto:pweinberger(a)aashto.org> All the bells and whistles are not yet in place (the tutorial needs updating still, among other things), but this set works substantially as the previous, so you all should be good to go.

[CTPP] PSAP -- Other criteria or principles for delineation?

by Reardon

Hi all, I imagine many of us are busy diving into GUPS and getting started with the delineation work. Obviously there are specific Census-defined thresholds for each type of statistical areas, but I’m curious to know if there are other criteria or principles that folks are using as they consider possible adjustments. Historical continuity aside, what makes for a good block group or tract? Should we seek to minimize heterogeneity by drawing boundaries that separate very different neighborhoods/sub-neighborhoods? Or is it better to have block groups/tracts that include a more diverse set of households and residents? I would imagine that the approach taken to these questions will affect not only the confidence intervals of the resulting ACS tables, but also the results of whatever research uses those tables. Any opinions or literature references on this topic would be most welcome!

Re: [CTPP] [Caution: Message contains Redirect URL content] Re: [State Data Centers] PSAP -- Other criteria or principles for delineation?

by Jon Chiappe

I would appreciate your paper please Patty. I was curious what others thought of the continuity as well as it would seem to limit some city planners From: Patricia Becker <pbecker(a)umich.edu> Sent: Monday, March 4, 2019 11:22 AM To: Reardon, Tim <TReardon(a)mapc.org> Cc: sdc_mlist(a)lists.berkeley.edu; ctpp-news(a)chrispy.net; joshua.wixom(a)census.gov; GEO PSAP (CENSUS/GEO) <geo.psap(a)census.gov>; Graham, Todd <todd.graham(a)metc.state.mn.us> Subject: [Caution: Message contains Redirect URL content] Re: [State Data Centers] PSAP -- Other criteria or principles for delineation? I wrote a paper about this 20 years ago; I'll be happy to send it to anyone who asks. In general, I think tract boundaries should be something - usually streets but sometimes water - that local people recognize as being a divider. Freeways are the highest priority, since they're difficult to cross. Then major arterial streets/roads. I also believe, and have said many times, that continuity is a shibboleth. That is, it's something everything thinks is of highest importance, but it really isn't. Good tracts for now and the future are more important. I almost completely retracted Detroit before the 1980 census, because when the tracts had originally been drawn -- after the 1930 census -- no one understood their purpose, plus the city had changed enormously with new freeways and urban renewal. I also use housing units rather than population counts as a size criterion. The ideal tract has about 1500 HUs. My reason for using HU counts is twofold: (1) the data are readily available, while pop counts are not, and (2) the sampling errors for ACS data ride on cases, which are households, not people. Hope this is helpful.

Re: [CTPP] Exploring Jobs/Housing Balance using the American Community Survey: Blog Posts

by Alan E. Pisarski

Chuck somewhere like slides 51-54 of this presentation from earlier this week, is my discussion of workers leaving their res county to work. it is a major national phenomenon which I have tracked over the years and Fairfax County is the poster child with an 8,000 difference between jobs and workers and about a half million flows across the county borders. I have looked at counties in Md where they have similar J/W ratios close to one and there are massive flows – so much for job worker balance as a solution! What we need is the soviet and Chinese approach where the electrical workers cooperative is housed just across the road from the electronics factory. Come to think of that we did that back in the bad old days—remember the pathetic houses clustered around the factory gate – the whistle blew and everyone went to work. I like your index idea – what I have used is the ratio of the potential workers crossing the border to the actual. Best, Alan Alan E.

[CTPP] Making the "best use possible" out of employer databases of employee home location zip codes

by Cervenka

Hello, My apologies to those who are on both the CTPP and TMIP lists, for a (much) more lengthy version of this question was recently asked on the TMIP list. What (if any) efforts have transportation planners made, in regards to comparing CTPP or LEHD-based home-work commuter flows to what can be obtained from employer databases containing the home location zip codes for all employees who work at specific geographic locations? Or comparison of information from travel model outputs of home-to-work flows to employer databases? I am particularly interested right now in whatever summary reports, memos or emails have been prepared, but will be happy to receive whatever feedback you might like to offer about successes or failures, either via a reply to the CTPP list, or directly to my email shown below. If you send anything directly to me, please let me know if you have any restrictions in place in regards to me sharing your comments with others. Thanks in advance!
