The Open Source Routing Machine (OSRM) is a C++ implementation of a high-performance routing engine for shortest paths in road networks. It combines sophisticated routing algorithms with the open and free road network data of the OpenStreetMap (OSM) project. Shortest path computation on a continental sized network can take up to several seconds if it is done without a so-called speedup-technique. OSRM is able to compute and output a shortest path between any origin and destination within a few miliseconds. Since it is designed with OpenStreetMap compatibility in mind, OSM data files can be easily imported. A demo installation is provided by our friends at Geofabrik. OSRM is under active development.

The key features of OSRM are:

• High Performance Routing Algorithm
• Easy import of OSM data files.
• Written entirely in C++ and available under the GNU Affero General Public License for anyone to use.
• Ability to handle continental sized networks.
• Influenced by current and ongoing academic research. [more info]

Platforms supported

Current version

Version 0.1 (July 10, 2010) is a baseline release. It has basic features. Version 0.2 (March 2011) is much faster and resource friendly. While it is safe to use this version, the code in git master branch is much more advanced.

Major improvements in version 0.3
