Vehicle Miles of Travel (VMT)
Daily Vehicle Miles Traveled – Multiplying AADT by the length of the road segment yields estimated daily vehicle miles traveled (DVMT). It is meant to represent traffic on a typical day of the year.
Annual Vehicle Miles Traveled – Multiplying the DVMT by 365.25 yields the annual vehicle miles traveled (AVMT). It is meant to represent the total traffic for the entire year.
