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 routes, trips, isochrones and travel distances matrices (travel time and kilometric distance).
This package relies on the usage of a running OSRM service (tested with v5.26.0 of OSRM).
You can run your own instance of OSRM following guidelines provided here. The simplest solution is probably the one based on docker containers.
> One request per second max. No scraping, no heavy
usage.
❗ To consider when using OSRM:
> “Most of the previously active core devs have either moved on to
new roles, or are simply busy on different projects
(…)”
-
osrmTableGet travel time matrices between points. -
osrmRouteGet the shortest path between two points. -
osrmTripGet the travel geometry between multiple unordered points. -
osrmIsochroneGet polygons of isochrones.
