Arterial traffic volumes are regularly counted throughout the County at key locations, or cordons. These cordon counts typically occur every three years and measure the number of motorized vehicles passing a specific location in a single day.
Traffic volumes on arterials throughout the County are key indicator of motorized activity and in part are a reflection of the County's efforts to minimize growth in single-occupancy vehicle (SOV) travel. Decreases in traffic volumes, or small increases relative to County and regional population growth, can be indicative of successes the County has made in implementing both land use and transportation policies, programs, and investments that encourage non-SOV use, including transit, bicycling, and walking. This measures supports the MTP Goal 2: Move More People Without More Traffic and Goal 5: Manage Effectively and Efficiently.
Overall traffic volumes on arterials throughout the County have decreased three percent between 2006 and 2012, even though the County population has increased by 9,000 residents, an increase of eight percent. Of the 14 counted locations, 11 of them show no increase or a decrease in traffic volume over this time period. Of the three arterial locations that showed an increase, only Arlington Boulevard, one of the most heavily utilized roadways in the County, showed a significant increase in actual volumes, increasing by 5,000 vehicles per day over that time period. This could be due in part to the effect of BRAC. It also serves a major East-West connection between Fairfax and DC resulting in large percentage of thru trips.
