Navigation system for finding optimum route using traffic incidents information
First Claim
1. 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 in a coverage area which includes a current position of a user of the navigation system and a calculated route to a destination where the coverage area is an area which is sufficiently large for encompassing possible routes to the destination other than the calculated route;
displaying a list of the traffic incidents that exist only on the calculated route to the destination on the navigation system;
selecting a traffic incident displayed on the navigation system to review a live image of the traffic incident downloaded through a wireless communication;
selecting two or more traffic incidents to be avoided on a route to the destination from the traffic incident list which shows the traffic incidents that exist on the calculated route to the destination; and
instructing the navigation system to calculate and produce a new route to the destination which does not have the selected traffic incident and displaying the new calculated route on the navigation system;
wherein the traffic incidents are listed on the traffic incident list by two or more different icons representing predefined types of traffic incident.

Abstract
A navigation system for finding an optimum route to the destination using traffic incidents information provides a novel approach to enable a user easily and quickly to select which incidents should be avoided. The user can easily identify the important traffic incidents because the system can display only the traffic incidents on the calculated route as well as all the traffic incidents in the converged area. The user can select the incident to receive more detailed information including a live image of the traffic incident and specify one or more incidents to be avoided on the route to the destination. The system calculates a new optimum route to avoid the specified traffic incidents. The traffic incidents are illustrated on the navigation system by two or more different icons representing predefined types of traffic incidents
