rerouteTraveltime(string, bool) -> None Reroutes a vehicle. If
        currentTravelTimes is True (default) then the current traveltime of the
        edges is loaded and used for rerouting. If currentTravelTimes is False
        custom travel times are used. The various functions and options for
        customizing travel times are described at http://sumo.dlr.de/wiki/Simulation/Routing

        When rerouteTraveltime has been called once with option
        currentTravelTimes=True, all edge weights are set to the current travel
        times at the time of that call (even for subsequent simulation steps).
