Abstract
A server 402 determines modified flow speed data for each navigable segment of a recommended navigable stretch. The modified flow speed data is determined so as to make the segment more favourable when a route is determined by a navigation device through the navigable network using the flow speed data. The server transmits the modified flow speed data to a set of one or more navigation devices 400 for use by the or each device at least for the purposes of determining a route through the network of navigable segments. Each navigation device then determines a route to a destination using the modified flow speed data.

21. A method of operating a navigation device in communication with a server, the navigation device comprising digital map data including data representative of a plurality of navigable segments of a navigable network, each navigable segment having attribute data representative of one or more attributes associated therewith, and the navigation device being further arranged to be able to determine a route through the navigable network using the attribute data associated with the navigable segments, the method comprising:
-
receiving, from the server, data indicative of modified attribute data for the or each navigable segment of a recommended navigable stretch, wherein the modified attribute data is determined so as to make the segment more favourable when a route is determined through the navigable network using the attribute data associated with the navigable segments; using the received modified attribute data in determining a route through the navigable network, said route including at least one navigable segment of the recommended navigable stretch; and using the existing unmodified attribute data for the at least one navigable segment of the recommended navigable stretch in determining a property of the determined route. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 34)

32. A navigation device comprising data storage means for storing digital map data including data representative of a plurality of navigable segments of a navigable network, each navigable segment having attribute data representative of one or more attributes associated therewith, the navigation device being capable of communicating with a server and being arranged to be able to determine a route through the navigable network using the attribute data associated with the navigable segments, the navigation device comprising one or more processors arranged to:
-
receive, from the server, data indicative of modified attribute data for the or each navigable segment of a recommended navigable stretch, wherein the modified attribute data is determined so as to make the segment more favourable when a route is determined through the navigable network using the attribute data associated with the navigable segments; and use the received modified attribute data in determining a route through the navigable network, wherein; (i) the recommended navigable stretch is at least a portion of a route to a destination determined by the server in response to a request by the navigation device;
or(ii) the recommended navigable stretch is a navigable stretch that provides an alternative route around one or more navigable segments that are to be avoided;
or(iii) the recommended navigable stretch is a navigable stretch that a user wishes to share with other users, the server having received an indication of the recommended navigable stretch from a user, and wherein the navigation device is a member of a predefined group of navigation devices for receiving information indicative of recommended navigable stretches suggested by other users;
or(iv) the recommended navigable stretch is at least a portion of a path being followed by a lead vehicle of a group of two or more vehicles wishing to travel in a convoy, and wherein the navigation device that receives the modified attribute data from the server is associated with one or more following vehicles

33. A navigation device comprising data storage means for storing digital map data including data representative of a plurality of navigable segments of a navigable network, each navigable segment having attribute data representative of one or more attributes associated therewith, the navigation device being capable of communicating with a server and being arranged to be able to determine a route through the navigable network using the attribute data associated with the navigable segments, the navigation device comprising one or more processors arranged to:
-
receive, from the server, data indicative of modified attribute data for the or each navigable segment of a recommended navigable stretch, wherein the modified attribute data is determined so as to make the segment more favourable when a route is determined through the navigable network using the attribute data associated with the navigable segments; use the received modified attribute data in determining a route through the navigable network, said route including at least one navigable segment of the recommended navigable stretch; and use the existing unmodified attribute data for the at least one navigable segment of the recommended navigable stretch in determining a property of the determined route.
