    摘要: This invention concerns a method of determining a route using map data comprising a plurality of navigable paths, the map data divided into a plurality of regions. The method comprises using at least one processing apparatus to: receive an origin and a destination on the map data and a travel time, determine a route from the origin to the destination using the map data and minimum cost data that identifies minimum cost paths between regions of the map data. The minimum cost data identifies more than one minimum cost path between a pair of the regions if different minimum cost paths exist between the pair of regions at different times and determining a route comprises identifying from the minimum cost paths for the pair of regions comprising the origin and destination, the minimum cost path having a lowest cost at the travel time.

    摘要: This invention concerns a method of determining a route using map data comprising a plurality of navigable paths, the map data divided into a plurality of regions. The method comprises using at least one processing apparatus to: receive an origin and a destination on the map data and a selection of one of a plurality of cost functions and determine a route from the origin to the destination using the map data and minimum cost data that identifies minimum cost paths between regions of the map data. The minimum cost data identifies more than one minimum cost path between a pair of the regions if different minimum cost paths exist between the pair of regions for different cost functions and determining a route comprises identifying from the minimum cost paths for the pair of regions comprising the origin and destination, the minimum cost path having a lowest cost for the selected cost function.
