Open Source Routing Machine

Linux / macOS	Windows	Code Coverage

High performance routing engine written in C++14 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 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.

Related Project-OSRM repositories:

• node-osrm - Production-ready NodeJs bindings for the routing engine
• osrm-frontend - User-facing frontend with map. The demo server runs this on top of the backend
• osrm-text-instructions - Text instructions from OSRM route response
• osrm-backend-docker - Ready to use Docker images

Quick Start

The easiest and quickest way to setup your own routing engine backend is to use Docker images we provide.

Using Docker

We base the Docker images on Alpine Linux and make sure they are as lightweight as possible (around 10-15 MB). In the following, replace X.Y.Z with the current stable release version.

wget http://download.geofabrik.de/europe/germany/berlin-latest.osm.pbf

docker run -t -v $(pwd):/data osrm/osrm-backend:vX.Y.Z osrm-extract -p /opt/car.lua /data/berlin-latest.osm.pbf
docker run -t -v $(pwd):/data osrm/osrm-backend:vX.Y.Z osrm-contract /data/berlin-latest.osrm
docker run -t -i -p 5000:5000 -v $(pwd):/data osrm/osrm-backend:vX.Y.Z osrm-routed /data/berlin-latest.osrm

curl http://127.0.0.1:5000/route/v1/driving/13.388860,52.517037;13.385983,52.496891?steps=true

Building from Source

The following targets Ubuntu 16.04. For instructions how to build on different distributions, macOS or Windows see our Wiki.

Install dependencies

sudo apt install build-essential git cmake pkg-config \
libbz2-dev libstxxl-dev libstxxl1v5 libxml2-dev \
libzip-dev libboost-all-dev lua5.2 liblua5.2-dev libtbb-dev

Compile and install OSRM binaries

mkdir -p build
cd build
cmake ..
cmake --build .
sudo cmake --build . --target install

Grab a .osm.pbf extract from Geofabrik or Mapzen's Metro Extracts

wget http://download.geofabrik.de/europe/germany/berlin-latest.osm.pbf

Pre-process the extract and start the HTTP server

osrm-extract berlin-latest.osm.pbf -p profiles/car.lua
osrm-contract berlin-latest.osrm
osrm-routed berlin-latest.osrm

Running Queries

curl http://127.0.0.1:5000/route/v1/driving/13.388860,52.517037;13.385983,52.496891?steps=true

Request Against the Demo Server

Read the API usage policy. Simple query with instructions and alternatives on Berlin:
