Agenda CTPP Basics Whats New with the CTPP? CTPP Parts and Tables CTPP software and online data access CTPP Resources

Slide 6

What is the CTPP? A Partnership effort between MPOs, DOT, FTA, FHWA, AASHTO, TRB and the Census Bureau. Set of special tabulations collected by the US Census Bureau. Designed by Transportation Planners for the purposes of Transportation Planning.

Slide 7

Variables Available TRANSPORTATION Place of Work Means of Transportation Workers per Vehicle Time Leaving Home Travel Time Vehicles Available SOCIOECONOMIC Minority Status Age of Worker Sex of Worker Household Income Poverty Status Occupation & Industry Class of Worker * Variety of Cross-tabulations available

Slide 9

Potential Applications Transportation planning: How many people commute from Belen to Albuquerque? What are some key employment destinations that may be appropriate for TOD? Travel Model Validation & Sample Design for travel surveys Employment Analyses: What are the most common destinations for work commuters? How do centers compare in terms of worker earnings, ages, industries? Targeted Analyses: How many workers work at home & in which industries? How is mode choice impacted by race? Age? Income? Vehicle Availability Generate Statistics: What is the average number of workers per vehicle? How many workers are there per household?

Slide 13

Non-Disclosure Rules US Code Title 13, Section 9 ensures that no published data can disclose an establishments or individuals identity Rule #7: Worker flows must have 3 un-weighted cases for each O-D pair CTPP 2000: 82 percent of tract-to-tract data & 89 percent TAZ-to- TAZ flow data were suppressed ACS 5-yr sample: about 50 percent of Census 2000 ensuring almost no flow data at TAZ or Tract level using suppression rules CTPP 2006 2010 uses data perturbation techniques & iterative proportional fitting, along with rounding and grouping methods

Slide 14

Two Sets of Tables Set A: Non-Disclosure proofed microdata Rounding, cell & table suppression Set B: Disclosure proofed microdata data perturbation methods applied, suppression rules lifted When using both, row and column totals wont match for the same population and geographies NCHRP 08-79 Producing Transportation Data Products from the ACS that Comply With Disclosure Rules http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_w180.pdf

Limitations Universe is often Workers only, 16 and over (no retirees, students, unemployed) Work Commutes only (no shopping, school trips, medical, etc.) Census Geography. No address point data (OnTheMap) Data suppression, rounding, grouping, synthesis Those darn ACS margins of error!

Slide 32

A word of caution CTPP 2006 2010 does not currently include workplace data for TAZs with zero (0) populations. This is being rectified and a new dataset will be released around January, 2014. This means that any TAZ which consists solely of a special generator (i.e., an airport, a shopping mall, a business park etc.) does not have workplace data or flow to it available. The data IS available at tract for Tracts with zero (0) population, so you can do Tract flows.
