Methods and systems for providing information indicative of a recommended navigable stretch
First Claim
1. A method of operating a server to provide information indicative of a recommended navigable stretch to a set of one or more navigation devices of a plurality of navigation devices in communication with the server, wherein the server has access to digital map data comprising 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 method comprising the server:
- receiving data indicative of a recommended navigable stretch that includes one or more navigable segments from among the plurality of navigable segments;
determining modified attribute data for the or each navigable segment of the recommended navigable stretch, wherein the modified attribute data is determined so as to make the or each navigable segment more favourable when a route is determined through the navigable network using the attribute data associated with the or each navigable segment; and
transmitting data indicative of the modified attribute data for the or each navigable segment of the recommended navigable stretch to the set of one or more of the navigation devices, the data indicative of the modified attribute data being configured to be used by the or each navigation device to make a corresponding modification of the attribute data for the or each navigable segment, so that a value of the attribute data for the or each navigable segment is changed by a respective receiving navigation device before determining, using navigation device position information acquired from a position sensing system of the navigation device, a route through the navigable network using the attribute data for the or each navigable segment.

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 favorable 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.

14. A server arranged to provide information indicative of a recommended navigable stretch to a set of one or more navigation devices of a plurality of navigation devices in communication with the server, the server having access to digital map data comprising 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 server comprising one or more processors arranged to:
-
receive data indicative of a recommended navigable stretch that includes one or more navigable segments from among the plurality of navigable segments; determine modified attribute data for the or each navigable segment of the recommended navigable stretch, wherein the modified attribute data is determined so as to make the or each navigable segment more favourable when a route is determined through the navigable network using the attribute data associated with the or each navigable segment; and transmit data indicative of the modified attribute data for the or each navigable segment of the recommended navigable stretch to the set of one or more of the navigation devices, the data indicative of the modified attribute data being configured to be used by the or each navigation device to make a corresponding modification of the attribute data for the or each navigable segment, so that a value of the attribute data for the or each navigable segment is changed by a respective receiving navigation device before determining, using navigation device position information acquired from a position sensing system of the navigation device, a route through the navigable network using the attribute data for the or each navigable segment.

15. 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 or each navigable segment more favourable when a route is determined through the navigable network using the attribute data associated with the or each navigable segment; and using the data indicative of the modified attribute data to make a corresponding modification of the attribute data for the or each navigable segment, so that a value of the attribute data for the or each navigable segment is changed before determining, using navigation device position information acquired from a position sensing system of the navigation device, a route through the navigable network using the attribute data for the or each navigable segment, wherein; 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; the recommended navigable stretch is a navigable stretch that provides an alternative route around one or more navigable segments that are to be avoided; 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;
orthe 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.

16. A non-transitory computer readable medium comprising computer readable instructions which, when executed by a server, cause the server to perform a method for providing information indicative of a recommended navigable stretch to a set of one or more navigation devices of a plurality of navigation devices in communication with the server, wherein the server has access to digital map data comprising 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 method comprising:
-
receiving data indicative of a recommended navigable stretch that includes one or more navigable segments from among the plurality of navigable segments; determining modified attribute data for the or each navigable segment of the recommended navigable stretch, wherein the modified attribute data is determined so as to make the or each navigable segment more favourable when a route is determined through the navigable network using the attribute data associated with the or each navigable segment; and transmitting data indicative of the modified attribute data for the or each navigable segment of the recommended navigable stretch to the set of one or more of the navigation devices, the data indicative of the modified attribute data being configured to be used by the or each navigation device to make a corresponding modification of the attribute data for the or each navigable segment, so that a value of the attribute data for the or each navigable segment is changed by a respective receiving navigation device before determining, using navigation device position information acquired from a position sensing system of the navigation device, a route through the navigable network using the attribute data for the or each navigable segment.
