OpenConditions

The live layer OpenStreetMap doesn't cover

OpenConditions is an open, self-hostable commons for what changes by the minute — road incidents,
closures, roadworks, congestion, and crowd reports — live in OpenMapX today, with transit occupancy and place busyness on the roadmap.

Complements OpenStreetMap, doesn't replace it

OpenStreetMap maps what's permanent. OpenConditions covers what isn't — incidents, closures, congestion, and signed crowd reports now, with transit occupancy and place busyness next. We never write back to OSM; we just point at it.

Open source, standards-first

OpenConditions speaks DATEX II, GTFS-RT, TraFF, Open511, and WZDx — no invented format, no new identifier scheme. Star it on GitHub, self-host it on your own server, or follow along on the blog.
