What you’re seeing: An interactive Leaflet map + animated D3 chart of pedestrian fatalities in the City of Albuquerque, 2012–2023. The SVI layer (CDC Social Vulnerability Index) is included to provide neighborhood context.

Quick notes:

  • About 14% of Bernalillo County residents live in tracts with SVI ≥ 0.8, yet across 2012–2023 roughly 49% of pedestrian fatalities occurred within or immediately adjacent to those tracts.
  • Fatalities involving a hit and run driver are trending up
  • Drug involved crashes are trending up while the proportion of alcohol only crashes are trending down
  • proportion of crashes occurring on the interstate is going up

Data: NMDOT/City of Albuquerque crash records (cleaned/normalized by me); SVI from CDC (tract-level, RPL_THEMES).
Tools: Leaflet.js, D3.js.
Caveats: Counts subject to reporting/geocoding limits; SVI provides context and does not imply causation.
Code/Method summary: Normalized fields for light conditions, hit-and-run, facility type (lane counts & intersections), and alcohol/drug involvement; bar chart stacks by facet; map points filter by year/facet; SVI choropleth binned at 0.20/0.40/0.60/0.80.
