Navigation device and method
First Claim
1. A navigation system, comprising:
- data storage device arranged to store at least;
digital map data;
traffic state information; and
places of interest data; and
one or more processing circuits operably coupled to said data storage device, said processing circuits arranged to perform operations for;
accessing said digital map data and calculating a route to a destination;
providing a user with navigation instructions to enable said user to progress along said route to said destination;
accessing, while said user progresses along said route to said destination, traffic state information and determining traffic status information relevant to said route to said destination, said traffic status information indicating a non-normal traffic condition that is occurring along said route, said non-normal traffic condition being a traffic condition likely to cause a delay in travel time when compared to a free flow of traffic;
determining an amount of expected delay to said user along the route due to said non-normal traffic condition;
while said user progresses along said route to said destination, accessing said places of interest data and determining selected information portions about places of interest associated with said route, said determining comprising;
filtering said places of interest data based on trigger conditions associated with information portions about places of interest in said places of interest data, said filtering comprising eliminating information portions about places of interest for which associated trigger conditions do not correspond to said amount of expected delay and a present time of day, and retaining information portions about places of interest for which associated trigger conditions correspond to said amount of expected delay and said present time of day;
generating a service alert based on said selected information portions about places of interest associated with said route, said service alert including an offering in view of the said amount of expected delay and said present time of day; and
presenting information based on said service alert, the presenting comprising presenting said amount of expected delay due to said current traffic status and said offering for said point of interest.

Abstract
Embodiments of the present invention relate to a navigation system, comprising data storage means arranged to store at least digital map data, traffic state information, and places of interest data, and a route planning module operably coupled to the data storage means and arranged to provide access to the digital map data and calculate a route to a destination, a traffic state interrogator operably coupled to the data storage means and arranged to access said traffic state information and to determine traffic status information relevant to said calculated route to the destination, a places data interrogator operably coupled to the data storage means and arranged to access said places of interest data and to determine relevant information portions about places of interest on the calculated route dependent on the determined traffic status information, and a navigation instruction generator operably coupled to the data storage means and arranged to generate navigation instructions including the relevant information portions about places of interest on the calculated route in response to the determined traffic status.

11. A method of navigation, carried out by a navigation system comprising one or more processing circuits and having access to digital map data and places of interest data, said method comprising:
-
accessing said digital map data and calculating a route to a destination; providing a user with navigation instructions to enable said user to progress along said route to said destination; accessing, while said user progresses along said route to said destination, traffic state information and determining traffic status information relevant to said route to said destination, said traffic status information indicating a non-normal traffic condition that is occurring along said route, said non-normal traffic condition being a traffic condition likely to cause a delay in travel time when compared to a free flow of traffic; determining an amount of expected delay to said user along said route due to said non-normal traffic condition; while said user progresses along said route to said destination, accessing said places of interest data and determining selected information portions about places of interest associated with said route, said determining comprising; filtering said places of interest data based on trigger conditions associated with information portions about places of interest in said places of interest data, said filtering comprising eliminating information portions about places of interest for which associated trigger conditions do not correspond to said amount of expected delay and a present time of day, and retaining information portions about places of interest for which associated trigger conditions correspond to said amount of expected delay and said present time of day; generating a service alert based on said selected information portions about places of interest associated with said route, said service alert including an offering in view of the said amount of expected delay and said present time of day; and presenting information based on said service alert, the presenting comprising presenting said amount of expected delay due to said current traffic status and said offering for said point of interest. - View Dependent Claims (12, 13, 14, 15, 16)
