High performance routing engine written in C++ designed to run on OpenStreetMap data.
The following services are available via HTTP API, C++ library interface and NodeJs wrapper: Nearest - Snaps coordinates to the street network and returns the nearest matches Route - Finds the fastest route between coordinates Table - Computes the duration or distances of the fastest route between all pairs of supplied coordinates Match - Snaps noisy GPS traces to the road network in the most plausible way Trip - Solves the Traveling Salesman Problem using a greedy heuristic Tile - Generates Mapbox Vector Tiles with internal routing metadata
To quickly try OSRM use our demo server which comes with both the backend and a frontend on top.
