Hi Martin, I have face the same problem. At last I found it caused by maxspeed=3 in the osm data. carFlagEncoder use 5 as factor of speed encoding. every number below 5 will be convert to 0.
Then you will have some edges in the graph with speed=0. *Best Regards,* *ZhiQiang ZHAO* On Thu, Jul 9, 2015 at 5:20 AM, Martin Sauvage <[email protected]> wrote: > Hello, > > I'm facing an issue when routing with shortest path between these 2 GPS > points: > 47.194150,-1.676384 > 47.197470,-1.671832 > > Caused by: java.lang.IllegalStateException: Speed cannot be 0 for > unblocked edge, use access properties to mark edge blocked!
