Transportation Statistics Office
These reports are produced in both annual and semi-annual versions.
The annual reports (first produced in 2006) include Daily Vehicle Miles Traveled (DVMT) that are
calculated from Centerline Miles (CLM) as of the end of the year of the report and Annual Average Daily
Traffic (AADT) as of the same calendar year of the report. The resulting DVMT are thus calculated
consistently, and the annual reports should be used whenever possible.
The semi-annual reports are done as of June 30 and December 31, and include DVMT calculated from CLM as
of the date of the report and AADT as of the previous calendar year. Because of this mix of dates,
the semi-annual report with DVMT that most closely matches the DVMT in the annual report is the one for
June of the following year. In other words, to generate a relatively consistent time series of DVMT data
from 2005 to 2008, it would be best to use the semi-annual report for June 30, 2006 (to get essentially
2005 DVMT) and then the annual reports for 2006 and thereafter.
