Monthly Vehicle Miles of Travel - May 2009

The Monthly Vehicle Miles of Travel (VMT) report for the California State Highway System gives the estimated vehicle miles driven and the resulting percentage changes in travel.

The links below are to this month's worksheets, and to charts illustrating percentage change and miles driven over a three year period.

January-April 2009 estimates were revised based on the final statewide vehicle miles of travel for year 2008 of 176.32 billion, and those revisions were used to produce May's report.

Final VMT was calculated from approximately 7,000 count sites, and the June through December 2009 reports will also be based on the final VMT for year 2008.
