Background: For the last two decades AASHTO has supported the production of Commuting in America and Commuting in America II based on special data sets prepared from decennial census Journey to Work data. The decennial system is to be replaced by an annual process called the American Community Survey (ACS). A transition process between the decennial document and annual systems needs to be developed.

The Commuting in America series has provided a sound, objective base for policy discussion of commuting-related issues in the past. This final edition will expand the state coverage of the document; link these data to other non-work related trip purposes data from the NHTS (National Household Travel Survey); and establish the linkages to the new ACS process.

The detailed census data are now becoming available. It is important to provide a synthesis of these data as early as possible for national and state public policy guidance. Reporting of the new ACS data also are intended to begin in the 2003-2004 period. Commuting in America III and its new elements will provide objective guidance and support for public policy considerations at the national and state level.

Objective:
Development of data and analyses to support a final document in the decennial series and to establish a strong platform for the new annual reporting series.

Status: The project is completed.

Product Availability: The final report has been published as NCHRP Report 550/TCRP Report 110.
