High-performance routing and map-matching server
The Open Source Routing Machine (OSRM) is an open-source router designed for use with data from the OpenStreetMap project.
In contrast to most routing servers, OSRM does not use an A* variant to compute the shortest path, but instead uses contraction hierarchies or multilevel Dijkstra's. This results in very fast query times, usually below 1 millisecond for data sets like Europe, making OSRM a good candidate for responsive, web-based routing applications and websites.
- Very fast routing
- Highly portable
- Simple data format makes it easy to import custom data sets instead of OpenStreetMap data or import traffic data
- Flexible routing profiles (e.g., for different modes of transportation)
- Respects turn restrictions, including time-based conditional restrictions
- Respects turn lanes
- Localized turn-by-turn instructions powered by OSRM Text Instructions
Services and applications powered by OSRM
- FOSSGIS routing service worldwide routing of car, bike, car profiles. Serves official demo instance.
- Cycle.travel biking directions
- Maps.Me offline mobile maps and directions
- Mapbox's Directions API (cycling profile only)
- I Bike Cph Copenhagen's bike route planner used OSRM in addition with third-party data.
- Geofabrik hosts an OSRM instance for commercial use (car profile only).
The OSRM project began with an initial public release on July 9, 2010, by Dennis Luxen. The next year, Luxen presented on OSRM at the ACM GIS '11 conference along with Christian Vetter. In 2015, Luxen stepped back from leading active development on OSRM. Mapbox's Directions team continues to maintain and contribute to the project. In early 2018, Mapbox hired the developers of the Valhalla routing engine which previously developed by Mapzen, and stopped its work on OSRM . After a period of development being nearly stalled, work on the project is slowly continued by new maintainers.
