Separate methods are provided for recalculation of a suitable route remainder, where an unanticipated timed turn or timed lane restriction or other traffic obstruction, such as a vehicle accident, is encountered enroute. Computations for an optimum route can be performed at the vehicle or at a station that communicates with the vehicle.
