Atlas · Realtime Ops
A live operations map tracking 40k vehicles in one view without melting a mid-range GPU.
Atlas coordinates citywide field operations. Operators watch the whole fleet on one screen; a stray event can mean a missed incident window.
The previous build dropped to 2fps above 2,000 vehicles. Operators couldn't trust the map, and battery died before the shift ended.
- 01
Decoupled data arrival from rendering: the wire updates state, the renderer picks when to draw.
- 02
Downsample points outside the viewport and lean on Mapbox's compositor for drawing.
- 03
Moved entity aggregation into a Web Worker synced to the map thread.
- 04
Profiled in DevTools until frame cost stayed under 8ms of budget.
The map is render-native — less than 3% of live entities touch the DOM; the rest are painted on the compositor.
40k+live entities
tracked at 24fps on mid-range hardware
- Sustained 24fps at 40k+ vehicles on mid-range hardware.
- Field incident response time improved ~18%.
- Battery draw on the ops tablets fell ~75% after offloading compute.
