Transportation Statistics Office
FDOT reports on State Highway System Mileage have traditionally been issued as
of June 30 and December 31 of each year, with the most current data available on
those dates. Since annual average daily traffic (AADT) for a calendar year is
not available until several months after December 31, the daily vehicle miles
traveled (DVMT) calculation for both the June and the December report uses AADT
from the previous calendar year in combination with the Centerline Miles
as of the current date. This hybrid DVMT is therefore completely correct
for neither the current nor the previous calendar year.
The new State Highway System Annual Reports are issued once a year, in the
Spring after the previous year's AADT data are available. Thus the DVMT data are
consistent and correct for the year being reported. We hope that data users will
take advantage of the new Annual Reports, but we will continue to provide the
Semi-Annual Reports for the time being, to allow for historical continuity.
