<div class="moz-cite-prefix">If you enable contraction hierarchies
you currently cannot do on-demand weighting. So disable CH in
config.properties (prepare.chShortcuts=no) or via
hopper.setCHEnable(false)<br>
<br>
If that is too slow, I fear you have to wait until we build the
more flexible but still fast routing algorithm.<br>

<div dir="ltr">Good day.
<div>We have modificate our project with this doc:</div>
<div><a moz-do-not-send="true"
href="https://github.com/graphhopper/graphhopper/blob/0.3/docs/core/weighting.md"
target="_blank">https://github.com/graphhopper/graphhopper/blob/0.3/docs/core/weighting.md</a><br>
</div>
<div><br>
</div>
<div>Parameters in config file:</div>
<div>prepare.chShortcuts=fastest<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>There is our method:</div>
<div><br>
</div>
<div>
<div>@Override</div>
<div>public double calcWeight( EdgeIteratorState edge,
boolean reverse )</div>
<div>{</div>
<div>/*</div>
<div> if(forbiddenEdges.contains(edge.getEdge()))</div>
<div> return Double.POSITIVE_INFINITY;</div>
<div>*/</div>
<div><br>
</div>
<div> double speed = reverse ?
encoder.getReverseSpeed(edge.getFlags()):encoder.getSpeed(edge.getFlags());</div>
<div> if (speed == 0)</div>
<div> return Double.POSITIVE_INFINITY;</div>
<div> double res = Math.random() *
edge.getDistance() / speed;</div>
<div> return res;</div>
<div> }</div>
</div>
<div><br>
</div>
<div>We want to simulate road jamm this way with Random
weighting, but there is no changes in result track. What
we are doing wrong?</div>
