Carbon Clock — Manhattan · Trip data
Trip data for The Carbon Clock — Manhattan, a 24-hour animated visualization of NYC traffic, emissions, and air quality.
This dataset hosts the largest trip-tier binary that exceeds GitHub Pages' practical cross-origin limits. The smaller tiers (25 K / 100 K / 500 K) live in the repo itself.
File: trips-2m.bin
- 2,933,898 trips — every yellow-taxi ride that started and ended in Manhattan during January 2025
- Source: NYC TLC Yellow Taxi Trip Records
- 2,933,750 trips routed through OpenStreetMap roads via OSRM v5 (148 kept their straight-line endpoints — 99.995% success)
- Geometry simplified with Douglas–Peucker (30 m tolerance) — preserves every turn, drops collinear noise
- 20,489,760 total waypoints, average 7.0 per trip
- Format: custom binary
CCM1— Uint32 offset table + RGBA color per trip + Float32 [lng, lat, seconds-since-midnight] per waypoint- ~40% the size of equivalent JSON
- Parses ~10× faster (zero JSON.parse cost; the points decode directly to a Float32Array that's pushed straight to the GPU as a Deck.gl
TripsLayerdata buffer)
- Size: ~257 MB
How it's used
The frontend at https://nirmitsachde.github.io/the-carbon-clock-manhattan/ fetches this file when the user selects the "Everything · 2.9 M" tier from the dropdown. Hugging Face's CORS headers make the cross-origin fetch work without any proxy.
