DATA's service area in Western Fairfax County

Strength In Advocacy

The Dulles Area Transportation Association started as a membership-based Association and although the organization has evolved into other areas of service, we remain an Association committed to providing value to our membership. When you join, you are gaining a seat at the table where regional transportation policy is shaped.

Who We Serve

As the designated Transportation Management Association for Western Fairfax County, DATA bridges public policy and private commute behavior. We provide proffer management and Transportation Demand Management strategies for the growth of the Dulles Corridor, working with planners, developers and local government to ensure transportation projects prioritize universal design and accessibility.
