This preliminary release will include weighted data representing the nation's daily travel. The data will be available on the NPTS data series website with a User's Guide and the on-line analysis tool at: www-cta.ornl.gov/npts
Spring 2003 - Second release (national sample with daily and long-distance trips).
The second release is the full continuum of travel for the nation, including daily and longer-distance (over 50 miles from home) travel. The reporting period for long distance travel was a 28-day recall period with the travel day as the last day.
Summer 2003 – The final, full data set is released for public use.
The final release includes all national data, daily and long-distance travel, plus the additional samples from the nine add-on areas correctly weighted and edited to represent the nation’s travel. Published results begin to be released with the final dataset.
Hope to see you at TRB!
