Abstract
A display method and apparatus for a navigation system for receiving traffic information and displaying traffic incidents in a manner easily and quickly comprehensible by a user of the navigation system. The navigation system applies various criteria to the traffic incidents and the route to the destination and determines an order of displaying the traffic incidents in accordance with the degrees of severity to the driving to the intended or calculated route to the destination. In other aspect, instead of assigning the listing order, colors are assigned to the traffic incident icons based on the degrees of severity.

11. A display method for a navigation system, comprising the following steps of:
-
receiving traffic information through a wireless communication device;
identifying locations of all of traffic incidents contained in the received traffic information in a coverage area which is dependent upon a current position of a user of the navigation system;
creating a predetermined size of square box centered at a current position of the navigation system;
finding a cross point on an intended or calculated route remaining to a destination which intersects with the square box and creating another square box of same size centered at the cross point;
repeating the foregoing steps for all of the remaining intended or calculated route;
prioritizing the traffic incidents based on parameters including whether or not the traffic incident is within the square boxes created in the foregoing step; and
displaying a list of traffic incidents in an order determined by said step of prioritizing the traffic incidents. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
