Maryland's Traffic Volume Maps by County
For The Years 2000 - 2006
The Traffic Volume Maps depict the Annual Average Daily Traffic (AADT) at various locations on Maryland's roadways. Traffic volume data is collected from the 3000 program count stations, 79 automated traffic recorders (ATR), and the 7 toll count stations located throughout Maryland. Program count data is collected on a three year cycle, while the ATR and toll count data is collected on a continual basis. The AADT figures, shown on these maps, are estimated. The AADT estimates were derived by taking 48 hour machine count data and applying factors from permanent count stations.

For more information about traffic counts and data, please see:
