Dear CTPP list and transportation data users, My apologies if you have already participated in this survey. Please participate in the Census Transportation Planning Products (CTPP) program web survey at: AASHTO CTPP Survey<http://www.surveygizmo.com/s3/1755727/AASHTO-CTPP-Survey> The CTPP 2006-2010 was released in fall, 2013. CTPP 2006-2010 has two significant differences from the CTPP 2000: 1) it is tabulated from American Community Survey (ACS)-based microdata; and 2) it incorporates synthetic disclosure-proofed data. In order to assess the utility of the 2006 - 2010 CTPP 5-year data product, a research team is conducting a web survey of CTPP users to better understand their issues, challenges, and opportunities in using the data for transportation purposes. The web survey effort seeks to shed light on the breadth of CTPP and ACS data usage. The survey results will also be used to develop analysis case studies to further evaluate the utility of the CTPP and ACS data. Please click the above link to participate in the web survey We hope you will complete the survey by September 12, 2014.
