<div>You can read more about contraction
hierarchies on GraphHopper <a href="https://github.com/graphhopper/graphhopper/blob/master/docs/core/ch.md" target="_blank">Wiki</a>.<br>
Essentially it's a post-import process during graph building that
makes routing faster, but plays with only one vehicle.<br>
<br>
And right now I think we cannot check a graph what features has
enabled.<br>
Only by opening and catching exceptions we can determine if CH is
on or off.<br>
I have opened an <a href="https://github.com/graphhopper/graphhopper/issues/285" target="_blank">issue</a>
for that.<br>
<br>
Maybe Peter can help more here, but the default settings for graph
creation is with them enabled.<br>
You need to study and change the config.properties file for
disabling them.<br>
