VEHICLE NAVIGATION USING TIMED TURN AND TIMED LANE RESTRICTIONS

摘要

Methods and apparatus for planning an optimum vehicle route from a selected origin (O) to a selected destination (D) with a selected departure time, taking account of the presence of timed turn restrictions (TTR) and/or timed lane restrictions (TLR). 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 (21) or at a station (30) that communicates with the vehicle.
