1. A navigation device, comprising:
- a processor; and
a memory store containing map data, the map data being modified with predetermined temporal information for a predetermined time period to include a temporally-variable feature, the predetermined time period including a start time and an end time or a start time and duration, a weight or cost attribute for each road segment associated with the temporally-variable feature, andthe processor being arranged to;
determine, in a route planning process, a status of the temporally-variable feature according to the temporal information,wherein the weight or cost attribute for at least one high capacity road within a predetermined distance from the temporally-variable feature is reduced to avoid a selection of low capacity roads in the route planning process between a start location and a destination location according to the status; and
provide at least one route determined in the route planning process.

7. A method of determining a route from a start location to a destination location, the method comprising:
-
determining, by a processor, a status of one or more temporally-variable map features according to temporal information using pre-determined temporal information related to the one or more temporally-variable features, the predetermined temporal information including a start time and an end time or a start time and duration, wherein the one or more temporally-variable features temporarily modifies map data for a predetermined time period; and determining the route from the start location to the destination location with respect to the status of the one or more temporally-variable map features using a weight or cost attribute for each road segment associated with the temporally-variable feature, wherein the weight or cost attribute for at least one high capacity road within a predetermined distance from the temporally-variable feature is reduced to avoid a selection of low capacity roads in the route determination between the start location and the destination location according to the status; and providing at least one determined route. - View Dependent Claims (8, 9, 10, 11, 17)

12. A system, comprising:
-
a server communicatively coupled to a navigation device, wherein the navigation device includes a data storage having first map data stored therein, the server being arranged to communicate second map data to the navigation device herein the second map data includes pre-determined temporal information identifying a temporally-variable map feature used modify the second map data for a predetermined time period, the predetermined time period including a start time and an end time or a start time and duration, a weight or cost attribute for each road segment associated with the temporally-variable feature and the navigation device being arranged to receive the second map data and to determine a route according a combination of the first and second map data, wherein the weight or cost attribute for at least one high capacity road within a predetermined distance from the temporally-variable feature is reduced to avoid a selection of low capacity roads in the route planning process between a start location and a destination location according to the predetermined time period; and provide at least one route determined in the route planning process. - View Dependent Claims (16)
