Working with open route service - removing roads from the graph
Dublin Transport map creator. Mapper. Open Data guy. Busting into the spatial planning & GIS world one step at a time.
Recently a friend of mine approached me with an interesting idea. Could we develop a directions API that would allow for legal routing of e-scooter journies using OSM data?
Enter the routing egines built on top of openstreetmap data -> openrouteservice, graphhopper, valhalla, etc.
So I settled on trying to modify the bike profiles of openrouteservice for our usecase
Note to future self - removing road from graph
Add the following to CommonBikeFlagEncoder.java to remove primary and primary_link tagged highways from the generated routing graph for bikes.
...
// setHighwaySpeed("primary", 18);
// setHighwaySpeed("primary_link", 18);
....
avoidHighwayTags.add("primary");
avoidHighwayTags.add("primary_link");
More to come as I learn more.
