The District Department of Transportation (DDOT) is committed to more sustainable transportation in Washington D.C. through improving mobility alternatives to single occupancy vehicles like biking, public transit, and carpooling. Currently nearly 45% of commuters drive alone, while biking accounts for just 0.6% of commuters. DDOT aims to decrease reliance on personal vehicles by increasing economic disincentives for driving alone and prioritizing infrastructure for shared transportation options.
