Abstract
Methods for planning an optimum vehicle route from a selected origin to a selected destination with a selected departure time, taking account of the presence of timed turn restrictions and/or timed lane restrictions. 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.
