Open Source Routing Machine
| Open Source Routing Machine|
Routing server, Contraction Hierarchies routing, extremely fast
Open Source Routing Machine (OSRM) computes shortest paths in a graph. It was designed to run well with map data from the OpenStreetMap Project.
In contrast to most routing servers OSRM does not use an A* variant to compute shortest path, but Contraction Hierarchies. This results in very fast query times, usually below 1ms for data sets like Europe, making OSRM a good candidate for responsive web-based routing applications and websites.
OSRM is currently maintained by Dennis Luxen.
