<div>Hi Alexandre,<br>
<br>
this is a bit explained in:<br>
<a href="https://github.com/graphhopper/graphhopper/wiki/Developers" target="_blank">https://github.com/graphhopper/graphhopper/wiki/Developers</a><br>
<br>
barriers are just OSM barriers. tower nodes are the nodes which
will end up in the graph and which are necessary for routing.
pillar nodes are nodes which have only a degree of 2 and are only
necessary to calculate distance and for proper displaying of the
final route. Those nodes end up in the wayGeometry only. This
separation speeds up routing, reduces import time and reduces
graph storage size. But causes some problems which will be finally
solved in the next release: <br>

I am just beging to dig in Graphhopper'code and I would like
to know if there is a description of the graph schema (what
are the edges and the nodes towards osm objects?). I get a bit
confused by TowerNodes, Barriers, Pillar Nodes etc).</div>
