Method Summary

boolean	computeNewRouteByComparison(int lastTime, int actTime, int origSpeed, int actSpeed) Decides whether a route should be recomputed or not because of the comparison of the speed on an edge.
boolean	computeNewRouteByEvent(int lastTime, int actTime) Decides whether a route should be recomputed or not because of an event.
int	getNumberOfRoutesByComparison() Returns how often has "computeNewRouteByComparison" returned "true".
