How I Built This

Data pipeline: Crash records queried from DCGIS ArcGIS REST API (MapServer layer 24), paginated at 1,000 records per call. 20,247 records for 2024. Coordinates are native WGS84.
Ward assignment: DC data includes a WARD field directly (Ward 1 through Ward 8). Records without a ward or coordinates are excluded.
Behavioral flags: DRIVERSIMPAIRED and SPEEDING_INVOLVED are pre-computed integer fields. Pedestrian and cyclist involvement from TOTAL_PEDESTRIANS and TOTAL_BICYCLES counts. Hit-and-run data is not available in this dataset. Injury severity uses KABCO breakdown by role (driver, pedestrian, bicyclist, passenger).
