Good day.
We have modificate our project with this doc:
https://github.com/graphhopper/graphhopper/blob/0.3/docs/core/weighting.md

Parameters in config file:
prepare.chShortcuts=fastest


There is our method:

@Override
public double calcWeight( EdgeIteratorState edge, boolean reverse )
{
/*
        if(forbiddenEdges.contains(edge.getEdge()))
            return Double.POSITIVE_INFINITY;
*/

    double speed = reverse ?
encoder.getReverseSpeed(edge.getFlags()):encoder.getSpeed(edge.getFlags());
        if (speed == 0)
            return Double.POSITIVE_INFINITY;
        double res = Math.random() * edge.getDistance() / speed;
        return res;
    }

We want to simulate road jamm this way with Random weighting, but there is
no changes in result track. What we are doing wrong?
