I would like to be able to use average speed data that I have gathered which assigns a speed for each OSM way. We are part of the way there in that we read the speeds in OSMReader.java put them in a speedsMap (see e.g. changes here made by my colleague: https://github.com/charanpald/graphhopper/commit/570088fbd11d4ff28f21c00e7c249dcfea2d2527). However the speeds aren’t being used for the routing.
My question sounds a bit similar to this one Custom OSM data speed limits but not quite. It looks like I would need to write a new Encoder class that maps from osm_id to int/double but I am not sure how to do this. Is there an example I can work from, and is this the missing piece?
Thank you for your help!
