Speed cannot be 0 for unblocked edge, use access properties to mark edge blocked! Should only occur for shortest path calculation. See #242.
I did investigate the area in OSM’s live data for anything tagged speed, maxspeed or minspeed=0 using Overpass Turbo but could not find anything. How could we proceed looking for the culprit? Which other values, tags or tag combinations would lead to a speed 0 in graphhopper?
In isochrone/src/main/java/com/graphhopper/isochrone/algorithm/Isochrone.java you mean, right? That’s the only occurence of “double tmpWeight” I could find.
I removed my tools/target directory and ran ./graphhopper.sh web europe_germanpbf again. Not sure that this is all what’s needed for a clean rebuild?
