Display Method and System for a Vehicle Navigation System
First Claim
1. In a navigation system having a user display for assisting a person in a vehicle traveling from a first location to a second location, a method for reducing the amount of traffic-related information provided to the person comprising:
- receiving the first location;
receiving the second location;
acquiring traffic-related information from an information supplier;
using the traffic-related information to determine a travel route for the vehicle from the first location to the second location;
wherein acquiring traffic-related information further comprises acquiring traffic flow information and traffic incident information associated with a coverage area that includes the first location and the second location;
wherein the traffic flow information and the traffic incident information include known conditions affecting traffic within the coverage area; and
displaying the travel route to the person via the user display, wherein the travel route is displayed along with the known conditions affecting traffic associated with one or more roadways and freeways within the coverage area.

Abstract
Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. The traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system. The user display may also automatically display traffic flow and traffic incident information for the direction that the user is traveling or along a route calculated by the navigation device. Further, a window displaying information about an upcoming traffic incident such as distance to the incident and incident details may automatically appear in the user display. Alternately, the user may select a roadway, freeway, or area for which traffic information is desired.

8. In a navigation system having an output screen provided in a vehicle, a method for displaying traffic information associated with a travel route from a first location to a second location, the method comprising:
-
retrieving location information associated with locations of one or more traffic flow sensors along the travel route; acquiring broadcast traffic information data from an information supplier, the broadcast traffic information data gathered from a coverage area that includes the travel route; determining whether the broadcast traffic information data includes traffic information associated with the locations of the one or more traffic flow sensors; displaying on the output screen a traffic icon corresponding to the traffic information associated with the locations of the one or more traffic flow sensors, if the broadcast traffic information data includes traffic information associated with the location of the traffic flow sensor; and displaying on the output screen a free-flow icon corresponding to free-flowing traffic associated with the locations of the one or more traffic flow sensors, if the broadcast traffic information data does not include traffic information associated with the location of the traffic flow sensor. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A navigation system for displaying traffic-related information to a person in a vehicle traveling within a coverage area, comprising:
-
a processor for controlling the operation of the navigation system; a position detection device in communication with the processor for determining a current position of the vehicle; a memory in communication with the processor for storing a road map, the road map comprising data associated with one or more roadways and freeways within the coverage area; a receiver in communication with the processor for receiving traffic-related information from a remote location, the traffic-related information including traffic flow data associated with one or more roadways and freeways within the coverage area; an output device in communication with the processor for displaying the traffic-related information to the person in the vehicle; a filter associated with the processor for filtering the received traffic-related information; wherein the filter is configured to control the output device to display detailed traffic flow data associated with roadways and freeways within a detail information area around the current position of the vehicle; and wherein the filter is configured to control the output device to display less detailed traffic flow data associated with roadways and freeways outside of the detail information area. - View Dependent Claims (16, 17, 18, 19, 20)
