Arlington TDM programs take more cars off the road eachweekday than the total of weekday rush-hour cars on I-66.
Only 44% of Arlington residents drive alone to work.
61% of the entire DC region drive alone to work.
Only 48% of Arlington workers with access to
commuter-assistance services drive alone to work.
87% of Arlington workers who drive alone don’t have
access to those services.
For every $1 Arlington contributes to TDM efforts, there is
an estimated return on investment of up to $9.
How is TDM implemented?
Charging for parking, marketing transportation options, employer transit benefits, and more.
