An interface between R and the 'OSRM' API. 'OSRM' is a routing service based on 'OpenStreetMap' data. See < http://project-osrm.org/> for more information. This package allows to compute routes, trips, isochrones and travel distances matrices (travel time and kilometric distance).
Interface Between R and the OpenStreetMap-Based Routing Service OSRM
OSRM is a routing service based on OpenStreetMap data. See http://project-osrm.org/ for more information. This package allows to compute distances (travel time and kilometric distance) between points and travel time matrices.
This package relies on the usage of a running OSRM service (tested with v5.22.0 of OSRM).
You can run your own instance of OSRM following guidelines provided here: https://github.com/Project-OSRM/osrm-backend.
The simplest solution is probably the one based on docker containers.
To set the OSRM server, use the osrm.server
option: options(osrm.server = "http://address.of.the.server/")
.
To set the profile ("driving" is set by default and it is the only profile available on the demo server), use the osrm.profile
option: options(osrm.profile = "name.of.the.profile")
.
A typical setup, corresponding to the Docker example, would be:
options(osrm.server = "http://0.0.0.0:5000/", osrm.profile = "driving")
⚠️ You must be careful using the OSRM demo server:
osrmTable
Get travel time matrices between points.
osrmRoute
Get the shortest path between two points.
osrmTrip
Get the travel geometry between multiple unordered points.
osrmIsochrone
Get polygons of isochrones.

This version should not break previous code.
This is a major release. Changes have been made to reflect the evolution of the OSRM routing service/engine. The backward compatibility is not ensured. The osrm package works with the version 5.0.0 of the OSRM API.
