This map service presents spatial traffic information at all different levels. Traffic data is collected at certain points along a roadway. Traffic data is then applied to segments of a roadway with a section length. Annual Average Daily Traffic (AADT) is multiplied by roadway section length and added up by county to result in Daily Vehicle Miles Traveled (DVMT) by counties. DVMT is then multiplied by 365 to obtain Annual Vehicle Miles Traveled (AVMT).
