The objective of this research was to develop data tabulations using secondary and publicly available sources to support the development of Commuting in America IV -- published as Commuting in America 2013 by the American Association of State Highway and Transportation Officials at https://traveltrends.transportation.org/Pages/default.aspx#.   Commuting in America 2013 is a series of 16 "briefs" describing various aspects of commuting:


  1. Overview
  2. The Role of Commuting in Overall Travel
  3. Population and Worker Trends
  4. Population and Worker Dynamics
  5. The Nature and Pattern of Jobs
  6. Job Dynamics
  7. Vehicle and Transit Availability
  8. Consumer Spending on Transportation
  9. How Commuting Influences Travel
  10. Commuting  Mode Choice
  11. Commuting Departure Time and Trip Time
  12. Auto Commuting
  13. Transit Commuting
  14. Bicycling and Walk Commuting
  15. Commuting Flow Patterns
  16. The Evolving Role of Commuting


The data tabulations, which use new and historical data sets and include documentation and source code, are organized in a single spreadsheet with 16 tabs - each corresponding to the Brief with the same number and should be useful to practitioners working at the federal, state and regional level.  The spreadsheet is available HERE
