Background
Where does DC’s crash evidence point to a safety intervention?
Vision Zero DC connects the District’s official collision records to trends, high-injury corridors, countermeasures and public decision-making. It separates observed crash patterns from proposed interventions and unverified bill statuses.

How It Works
- Overview: Deaths, serious injuries, modes and ward burdens are read from a dated snapshot.
- Map: Live incident queries expose crash case files, filters and moving-violation context.
- Corridors: DDOT’s High Injury Network is joined to crashes; profiles and a sortable corridor table show the underlying measures.
- Law tracker: Enacted laws, pending proposals and implementation pointers retain their different statuses.
- ANC briefs: Ward-scoped findings support editable resolution drafts and links to the officials who can act.
