Additional reports and tables, based on statistics from the American Community Survey, examine U.S. residents traveling across county and state lines to work. Specifically, the products present U.S. workers who have commutes of 60 minutes or longer and workers who have "mega commutes" of at least 90 minutes and 50 miles.

tract level data

by Harun Rashid

CTPPers, have any of you done flow analyses at tract level? With each CTPP release, we conduct that for small planning areas. For this, we need tract-tract flows with numbers from A302100 table. In identifying commuter flows to downtown urban core of the region (Charleston MSA, South Carolina), we found very large MOEs for each tract-tract pair. Of a total of 940 tract-tract pairs identified to have flows to the study area, 622 have MOEs larger than estimates! I am checking to see if anyone else experienced the same issue, and how this is being handled. I was thinking of using some sort of filters, e.g. considering only the pairs that have estimates larger than MOEs. Any suggestions will be appreciated. TIA.

37 Billion Mile Data Challenge

by Reardon , Tim

I wanted to make sure folks on this listserv are aware of our "37 Billion Mile Data Challenge" which should be of interest to researchers, modelers, and transportation planners across the country. Individuals, academics, teams, and companies are all welcomed and encouraged to participate. Visit www.37billionmilechallenge.org<http://www.37billionmilechallenge.org> for complete details. MAPC just launched a 6-week data challenge to help unearth the lessons to be found in an unprecedented new dataset about vehicle ownership and usage. The Massachusetts Vehicle Census contains anonymized information about the make, model, age, estimated mileage, fuel efficiency, and zip code of every passenger and commercial vehicle registered in the state from 2008 to 2011 AND a spatial dataset of 250 meter grid cells with statistics on number of vehicles, vehicles per household, mileage per vehicle, and greenhouse gas emissions. Few researchers have ever had access to this type of information and we are opening the doors to everyone who wants to try their hand at making a beautiful visualization, an insightful analysis, or a useful tool out of this big data. In particular, we're looking for submissions that will help guide the actions that the state and its communities are taking to build a more sustainable transportation system. Judges include the Massachusetts Secretary of Transportation and the public, who will be able to vote for their favorites online. Winners will walk away with cash prizes and recognition from the Commonwealth. Visit www.37billionmilechallenge.org<http://www.37billionmilechallenge.org/> to learn more or follow along on twitter @37billionmiles. Challenge closes on April 19. ___________________________________ Timothy G.

Poe Bill Canceled

by Ed Christopher

Just got this from the Census Project folks. ------------------------------ Late yesterday, the House Committee on Oversight and Government Reform announced that it cancelled its scheduled markup of the Poe bill to make the American Community Survey voluntary. This is a tremendous victory for the many individual stakeholders working with the Census Project who either directly contacted individual members of Congress between Friday morning of last week and late yesterday to express opposition to the legislation, or who signed the co-signature letter (http://thecensusproject.us6.list-manage.com/track/click?u=2d1784c40f46dfe51…) to Congress. The letter itself (http://thecensusproject.us6.list-manage.com/track/click?u=2d1784c40f46dfe51…) has been revised in light of developments and was still sent to the committee to put us on record as opposed to the bill. Thanks to everybody for their help. Together we secured an important victory! -- Ed Christopher

ACS in trouble again

by Ed Christopher

I got this from our friends at the Census Project. The U.S. House of Representatives is at it again! Next Wednesday, March 12, the House Committee on Oversight & Government Reform will hold a meeting to mark up Congressman Ted Poe’s (R-TX) bill to make the American Community Survey (ACS) voluntary. If the ACS is made voluntary, participation rates would drop dramatically and the value of the survey would substantially decline. Census Project Co-Director Terri Ann Lowenthal explains the issue in a new blog post today (http://censusprojectblog.org/2014/03/07/from-the-ashes-the-poe-bill-rises-a…). Additional information about the ACS is contained in a series of fact sheets developed by the Census Project (http://www.thecensusproject.org/factsheets.htm), and in a March 2012 letter to Congress (http://www.thecensusproject.org/letters/2012-03-06_Census_Project_voluntary…), from when the House made a similar move. The Census Project only learned of the committee’s intentions last night. We realize it’s a quick turnaround, but we hope your organization can co-sign a letter to congressional leadership (http://www.thecensusproject.org/letters/2014-03-acsbill/CensusProjectACSltr…) by 4:00 p.m. (Eastern) on Monday, March 10. We will then send this important letter to Congress and issue a press release on Tuesday in advance of the committee hearing on Wednesday. If your organization can co-sign the letter (http://www.thecensusproject.org/letters/2014-03-acsbill/CensusProjectACSltr…), please contact Jason Shevrin at jason.shevrin(a)gmail.com by 4:00 p.m. on Monday The Census Project http://www.thecensusproject.org/ -- Ed Christopher
