<div>Hi Martin,<br>
<br>
hmmh, if the speed is somehow calculated to be 0 then the access
should be set to false making the ferry no longer available. And
if the speed is not 0 then the exception should not be thrown.<br>
<br>
Additionally in this case I see that the unknownSpeed *should* be
selected but it should be 5km/h (living_street):<br>

<br>
Maybe you can debug this a bit and tell if the speed of the edge
is 0 or not and why.<br>
<br>
Also when switching branches make sure you remove the target
folders and/or rebuild in your IDE.<br>

<div>Hi Martin, Hi ZhiQiang,<br>
<br>
this could be related to the bug ZhiQiang mentioned but
this was already fixed:<br>
<a href="https://github.com/graphhopper/graphhopper/issues/367" target="_blank">https://github.com/graphhopper/graphhopper/issues/367</a><br>
<br>
This can only occur for shortest path routing:<br>

<br>
Martin, do you use master or a 0.4 branch?<br>
<br>

<div>I have face the same problem.</div>
<div>At last I found it caused by maxspeed=3 in the

<div>carFlagEncoder use 5 as factor of speed

<div>every number below 5 will be convert to 0.</div>

<div>Then you will have some edges in the graph with

<div>Hello,</div>
<div><br>
</div>
<div>I'm facing an issue when routing with
shortest path between these 2 GPS points:</div>
<div>
<div>47.194150,-1.676384</div>
<div>47.197470,-1.671832</div>
</div>
<div><br>
</div>
<div>Caused by:
java.lang.IllegalStateException: Speed
cannot be 0 for unblocked edge, use access
properties to mark edge blocked! Should only
occur for shortest path calculation. See
#242.</div>
<div><br>
</div>
<div>I suspect the shortest route tries to
take the ferry (Bac Indret) with no defined
speed while the fastest route provides:</div>
<div><a href="https://graphhopper.com/maps/?point=47.19415%2C-1.676384&point=47.19747%2C-1.671832&locale=fr-FR&layer=Lyrk" target="_blank">https://graphhopper.com/maps/?point=47.19415%2C-1.676384&point=47.19747%2C-1.671832&locale=fr-FR&layer=Lyrk</a><br>
</div>
<div><br>
</div>
<div>Is it a GH bug or an OSM data issue? Is
there any way to fix this crash (do not take
ferry with shortest route) ?</div>
<div><br>
</div>
<div>Thanks,</div>
