Patent ID: 8355865

Claim:
A method of providing travel time information for a plurality of positions on an electronic map comprising the steps of: providing map data containing information on road segments; determining a plurality of road segment travel times based on the map data, where a road segment travel time for a road segment corresponds to a travel time from a start point to a point on the road segment; selecting a plurality of positions for which travel time information is to be provided based upon comparing the road segment travel times to one or more pre-defined times, where the plurality of the positions are located in an area at least partially surrounding the start point; defining a tiling covering the area, where for each tile of the tiling, a road segment travel time is respectively determining for a road segment located in the tile and having maximum travel speed in the tile; and displaying an optical indicator for the respective travel time information for each of the plurality of positions on the electronic map, where the optical indicator includes an alphanumeric string representing an estimated arrival time and where the optical indicator comprises a line or a surface pattern on the electronic map indicative of a region that can be reached within a given travel time.
