3. National Household Travel Survey

4. Obtains trips from one address to another by all modes…

5. NHTS Core Data Content  Household  Income, composition, location  Person  Age, sex, race, ethnicity, worker and student status, citizenship, education  Geography  High level geography – urban, rural, suburban, state and national analyses  Vehicles  Make, model, year, mileage, alternative fuels, commercially licensed  Trips  Mode, time of day, purpose, vehicle occupancy, distance, trip length

6. NHTS – Two Components  National Study  Serves USDOT, Congress, and White House  Resource for State, metro areas (MPOs), etc.  40 years of trend data on U.S. travel behavior  Sample size: 25,000 households  Add-On Program  Service to States and MPOs since 1990  Allows States and MPOs to purchase additional samples  2008 sample size: 125,000 (a doubling from 2001)

7. 125,000 Add-On Samples NHTS – Add On

8. Survey Design - New for 2008  Allows for valid statewide data-- minimum sample (n=250)  Cell Phone only sample  Customizable content for Add-On participants  New data items for national study

9. New 2008 NHTS Content  Congestion  Interstate use and tolling  Telecommuting – opportunity and frequency  Work arrival time and flexibility  Safety  Safe Travel to School  Travel impacts of disability  Energy and Environment  Shopping by Internet and deliveries to the household  Hybrid/Alternative fuel vehicles  Fuel costs by vehicle type and travel behavior  Vehicle age, odometer reading, and annual mileage  Alternative Modes  Access (to transit) travel party size  Frequency of walk and bike  Motorcycle ownership and use

10.  April 2009 - Data collection completed  June 2009 - Final unweighted data for QA  August 2009 - Add-On GIS files  August 2009 – Draft final weighted file for QA  October 2009 – Final weighted data and documentation  Add-Ons receive final data  January 2009 – Public use data set  On-line analysis tool available for 2008  March 2009 – Final full documentation and users guide 2008 NHTS Schedule

17. and a Tool. –Online, free, 24/7, interactive –Mapping complex data for those without GIS knowledge or resources –Allows sophisticated queries based upon standard Census geography… …Or from arbitrary block-based areas. What is OnTheMap?

18. Start with LED data infrastructure Employment information based upon Quarterly Workforce Indicators (QWI) Residential information and origin- destination relationships synthesized –From PCF, 2000 Decennial Census, ACS, and StARS as well as SIPP and CPS –CTPP informs the prior How is the Data Constructed?

19. QWI and OnTheMap workplace data protected by dynamically consistent noise infusion applied at the establishment level –Ramp distribution with a hole in the middle OnTheMap residence, origin/destination, and QWI-suppressed workplace employment are protected by synthetic data –Multinomial/Dirichlet PPD Add noise and protections

20. OnTheMap Application Download from VirtualRDC –Hosted by Cornell University –Same data as in the application –Block based –Multiple labor segments How to Access the Data?

37. C ensus T ransportation P lanning P roducts The CTPP embodies a collection of Census Data used for Transportation Planning. With changing data needs and the ACS, there will be a variety of different products useful for transportation planning emanating from Census Data. There will be Special Tabulations, Standard Tables and even Value Added-products. The CTPP captures all of these. Think of CTPP as a place to look for Census Data products to help with your Transportation needs Enter the ACS era…
