[CTPP] NextGen NHTS Pooled Fund Program Open House at TRB

by sgbricka＠gmail.com

*Apologies for cross-postings FHWA is establishing a new pooled fund program in support of the next generation National Household Travel Survey (NHTS). The NextGen NHTS will integrate passive data with household travel surveys to provide both long-distance and local travel behavior data on an annual basis. We invite you to come and learn more about this new pooled fund effort while at TRB: What: NextGen NHTS Pooled Fund Program Open House When: Monday 1/8, 1-2 pm Where: Convention Center Conference Room 302 This pooled fund is designed to bring together agencies considering their next household travel survey program in order to learn from each other's experiences to date and design the NextGen NHTS. Pooled fund participants will identify design elements and benefit from research into critical questions about the evolution to a hybrid travel behavior data source, including guidance for evaluating passive data opportunities and benchmarking results. Whether you just completed a household travel survey or are actively researching your 2020 survey program, this pooled fund program will equip your agency with the research and results needed to meet local and long distance travel behavior needs on an annual basis. We hope to see you at TRB! For more information or to RSVP, contact: Wenjing Pu, PhD, PE DOT | FHWA | Office of Highway Policy Information (202) 366-5024 wenjingpu(a)dot.gov <mailto:wenjing.pu(a)dot.gov>

Re: [CTPP] Non-Traditional CTPP Users

I'm a demographer in private practice. I used CTPP data when I did a demographic study for the city of Hartford, CT. I'm familiar with UTPP/CTPP going back decades, so it's not like I had to discover that the data existed. But it was very useful for city officials to understand more about people who work in Hartford, as well as about those who live there. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Thu, Dec 28, 2017 at 2:55 PM, Benjamin Gruswitz <bgruswitz(a)dvrpc.org> wrote: > Some discussion came up at our recent conference in Kansas City about > earlier days of the program when public sector employees would get data > request from folks in various private sector industries.

[CTPP] Non-Traditional CTPP Users

by Benjamin Gruswitz

Some discussion came up at our recent conference in Kansas City about earlier days of the program when public sector employees would get data request from folks in various private sector industries. The CTPP Board Training & Outreach subcommittee wanted to generate an anecdotal list from listserv members of who they know using the data--beyond more traditional public sector transportation planners and their consultants. This could be some non-traditional research area at a university, some more obscure public agency use case, or a private sector application. Knowing not only who is using it but what they're using it for is always a plus. Feel free to reply to the listserv or me directly. Thanks in advance!

[CTPP] NHTS Task Force (ABJ45T) Activities at TRB 2018

by Krishnan Viswanathan

Apologies for cross posting. The link to the activities of the NHTS task force (ABJ45T) at TRB 2018 can be found here: http://rpubs.com/matungawalla/ABJ45T_2018AM Treats include: 1) Want to know about the 2017 NHTS? - Find out at Session 336 2) Want to know how to visualize NHTS data? - See it at the Task Force Meeting 3) All you wanted to know about large passive data but were too afraid to ask :-) - Ask away at Session 403 4) How does Freight interact with Household Travel? - Session 738 might have some answers. Happy Holidays, Krishnan -- Krishnan Viswanathan Chair, ABJ45T

[CTPP] Ctpp 2000 data-- block groups available for TX, NE, SC, WV, RI, and DC?

by Humann

NONCONFIDENTIAL // EXTERNAL Hi, I'm trying to get 2000 CTPP data at the block group level from the BTS/transtats website for all states plus DC. I cannot find block group level data for D.C., Nebraska, Rhode Island, South Carolina, Texas, and West Virginia. Doe anyone know if these these data are just not available? Or if this is a website glitch? I have not found any information yet that would indicate that the block group level CTPP 2000 data is not available for these 5 states (plus D.C.). Any help will be greatly appreciated. Thanks, McKenzie

Re: [CTPP] The Washington Post: Scientists can now figure out detailed, accurate neighborhood demographics using Google Street View photos

by Cervenka

The series of posts from last week remind me that the idea of estimating “household demographics” based only on observed vehicle types has been around since the 1990s, as planners have tried to figure out whether the actual observed distribution of vehicle types seen on toll lanes are noticeably different from the observed distribution seen on non-tolled roads that offer a viable (but probably slower and/or less reliable) alternative to the toll lanes, and if so what this might mean (statistically speaking) in regards to differences in the likely distribution of household income for toll-road users and non-users. I am not an expert on such matters, so will avoid offering any personal opinions about the “likely statistical accuracy” of such an observation-based analysis, beyond noting that the term “Lexus lane” is often used, and often gets people into some rather contentious point-counterpoint debates about who actually “directly benefits” from the availability of faster and/or more reliable tolled facilities.

Lots more pick-ups in some parts of the country than others. Subarus ALL have 4-wheel drive, and they are consequently a very popular make in my county. Japanese makes of cars (e.g., Honda) have long been more popular on the West Coast (regardless of ethnicity) than in the Midwest, where there is stronger brand loyalty to American makes manufactured in the Midwest (in theory – many are now made in Mexico). Even if one accepts the underlying premise of correlating vehicle types to demographics and voting patterns, I think Ed’s suggestion of processing vehicle registration files instead of Google photos is right on target. Much easier. And it wouldn’t surprise me if users of Big Data for political analysis are already doing this.

There’s a big difference in neighborhoods where you find concentrations of say 2018 Range Rovers versus 1964 Ford Mavericks. Plus one to Thomas’s point about high density areas where people either don’t own vehicles or park the vehicles they do in garages. The same lack of sample would also apply to where HOAs dictate that all vehicles must be parked in personal garages with the door lowered. Perhaps lack of variation in the paint color scheme could be used as an explanatory variable for such neighborhoods.

Re: [CTPP] The Washington Post: Scientists can now figure out detailed, accurate neighborhood demographics using Google Street View photos

by Marchwinski

Does anyone know if they looked at how well the model they developed predicted demographics in low car ownership areas like New York City, where less then half of the households have cars? It did not seem like they used any data from the NY area. In built up, high density areas, many of the cars are in structured parking or people do not own cars. On-Street cars may not represent who is living in the area. Same for high density areas in other cities.
