[CTPP] TRB Tools of the Trade Conference - Registration is Open!

by Schiffer

Registration is now open for the 2016 TRB Tools of the Trade Conference: http://www.trbtoolsofthetrade.org/upcoming-conference.html "Tools of the Trade is a national conference providing practical techniques for transportation professionals in small (under 50,000 residents) and medium-sized (50,000 to 250,000 residents) communities. All practitioners, researchers, academics and others involved in the transportation community are encouraged attend. The conference is sponsored by the Transportation Research Board Committee ADA30, the Federal Highway Administration, the Berkeley-Charleston-Dorchester Council of Governments, and the South Carolina Department of Transportation." I will be moderating two sessions on travel demand modeling applicable to small and medium-sized communities. Some of the other sessions cover performance based planning, scenario planning, freight planning, and Big Data (for small areas). The conference will be held in historic Charleston, South Carolina on September 12-14, 2016. We hope to see you there! -Rob Robert G.

[CTPP] ABJ30(1) seeking ideas for research statements

by Mara Kaminowitz

An important function of TRB is to stimulate research that addresses concerns, issues, or problems facing the transportation community. In support of this function, TRB committees identify and develop research need statements (RNS) for use by practitioners and researchers. A list of RNS can be found here: https://rns.trb.org/. The Census subcommittee (ABJ30(1)) wants to develop 2-3 research needs statements with the goal of submitting one for NCHRP funding. We want your ideas for possible research topics. Data methods as well as applied uses are welcome. The idea needs to involve a Census product (including CTPP) and should be related to transportation and urban data. You can also include things like potential benefits, relevance to the transportation community, and the end product you envision. We will be assembling a small team to consider the ideas and develop some of them into full research needs statements. Please send an email directly to mkaminowitz(a)baltometro.org and clara.reschovsky(a)dot.gov with your ideas by August 1. We look forward to hearing from you!

[CTPP] New information on the commute map animation.

by Mark Evans

I added a table below the map that contains some additional information. It isn't very intuitive and it's hard to describe in the short column headings in the table (I'm open to suggestions) but I'll leave a couple of notes here and add some explanation to the production page later. In the table, I have totals for each of the counties involved in the selected commuter flows. This includes a "median" commuting distance for commuters who live in the county and a median commuting distance for commuters who work in the county. In addition at the right side of the table, there are a couple of percentages: - the "% This County" shows the % of that county's residents are part of the main selected county's workers (if "workplace" is the selected view) or the % of that county's workers who are part of the main selected county's residents (if "residence" is the selected view.) - the % Selected County shows the % of the selected commuters who live/work in this county (depending on the selected view), so these should add to 100%. The median distances are calculated using the same number that drives the distance range criteria: the distance between the center of each census tract. Thus, intra-tract commutes count as 0. By sorting the tracts by distance, I found the tract-tract flow that contained the median commuter (if 1,000 commuters, the 500th commuter) and used that flow distance as the median. Anyway, if nothing else the totals on the left side of the table will show you what I have as the total workers/residents in my tables. Thanks and let me know if any suggestions or questions, Mark

Re: [CTPP] CTPP animation map (Not CTPP, actually)

by Ed Christopher

Thanks Mark for the changes. When I get the time I will write my missive on why it is important to have flow data without any suppression and why MOEs/CVs do not matter for OD pairs when it comes to transportation planning--unless others on this list want to comment on it.

Re: [CTPP] CTPP animation map (Not CTPP, actually)

by Marchwinski

Mark- Since you are using 2006-2010 tract data, could you do a visualization by mode, at least at a high level like the 2009-2013 ACS? That would involve summing the data to 4 modes: auto drive alone, auto carpool (all other auto occupancies), public transit (sum all transit modes) and “Other” which includes everything else, but is mostly walk, bike, taxi and motorcycle. I realize there are less valid data points, but you could see how different transit was compared to drive alone.

Re: [CTPP] ACS Commute Visualization

by Jingjing Zang

Hi Mark, Thanks for the explanation! I’m looking at Montgomery county as an example, but had trouble duplicate the results. I’m assuming that the trip distance filter was the cause. I wonder how you apply the trip distance filter? Is it defined by distance between centroids of residence and workplace tracts? Thanks, JJ From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Mark Evans Sent: Thursday, May 26, 2016 3:34 PM To: ctpp-news(a)chrispy.net Subject: [CTPP] ACS Commute Visualization Hey - hope this goes through. I'm Mark Evans and I developed the commuter map. Ed Christopher told me about this listserv. I'm happy to answer any questions that you may have. I think Penelope mentioned it elsewhere, but the data is from the 2006-2010 ACS tract-tract commuter data<https://www.fhwa.dot.gov/planning/census_issues/ctpp/data_products/2006-201…>. I calculated a CV using the estimate and the MOE. I've seen some warnings about the high level of error in some of the ACS data with recommendations to include only data with CV < 30-40%. Unfortunately, this removes almost all the data, so the default setting I used is 80%. Even at this high level, it excludes a portion of the estimated commuters at the tract level. In addition, anyone who works and lives in the same tract would not be included. Thanks for taking a look!

[CTPP] Census Products of Note

by Ed Christopher

In today's media release the Census Bureau announced its upcoming schedule for product distribution. In it were some "new" products that may be of interest to people on this list. I will highlight a few below. Here is the link to the entire media release . http://www.census.gov/newsroom/press-releases/2016/cb16-101.html In December we will see our first release of two non-overlapping 5-year ACS data sets (2006-2010, and 2011-2015) . On Thursday, July 21, 2016 we will see several "NEW" products. 1. 2014 Supplemental Estimates: This new product will consist of 58 detailed tables tabulated on the 2014 one-year microdata for geographies with *populations of **20,000* or more. These supplemental estimates will be released on American FactFinder and the Census Bureau’s application programming interface, and will be available for the same geographic summary levels as those in the American Community Survey 1-year dataset. 2. Statistical Testing Spreadsheet : This ACS statistical comparison tool will allow users to carry out statistical testing for two or more ACS estimates using the margin of error to determine whether the estimates are significantly different (higher or lower) from each other or are not significantly different (statistically tied) from each other. In our CTPP world we also know of two other tools. One developed by the NY State Data Center (https://sdcclearinghouse.wordpress.com/2009/03/03/spreadsheet-to-calculate-…) and another one developed by CUTR at the University of South Florida (http://www.nctr.usf.edu/abstracts/abs77802.htm). 3. 2010-2014 replicate tables: This new product will provide expanded versions of 107 detailed tables that are published in American FactFinder. In addition to the published estimates and margins of error, 80 replicates for variance calculations are also provided. This product is intended for advanced users and will allow them to calculate the margins of error when aggregating across geographies or collapsing categories within tables without using approximation formulas. The replicate tables will be released on the FTP site with links available on American FactFinder. -- Ed Christopher Transportation Planning Consultant 708-269-5237
