Abstract

A method of providing emergency route guidance to guide users away from a disaster includes receiving from a user a request for emergency route guidance through a user interface of a portable electronic device. The method further includes determining the current location of the portable electronic device with a position receiving device, presenting a list of possible disaster types to the user through the user interface of the portable electronic device, and receiving a selected disaster type from the user. At least one suggested route is generated for the user to follow using route software of the portable electronic device according to the selected disaster type and the current location of the portable electronic device. Navigation instructions are then provided for guiding the user on the suggested route in order to avoid the selected disaster type.

Claims

1. A method of providing emergency route guidance to guide users away from a disaster, the method comprising:

receiving from a user a request for emergency route guidance through a user interface of a portable electronic device, the portable electronic device further comprising a map database for storing map data including road information and elevational data, route software for creating navigation instructions for generated routes, and a position receiving device receiving position signals indicating a current location of the portable electronic device;

determining the current location of the portable electronic device with the position receiving device;

presenting a list of possible disaster types to the user through the user interface of the portable electronic device;

receiving a selected disaster type from the user while not receiving any specific destination from the user;

generating, with a processor of the portable electronic device, at least one suggested route for the user to follow by executing the route software of the portable electronic device according to the selected disaster type, and the current location of the portable electronic device, and the elevation data of surrounding areas, wherein locations with higher elevations are avoided when the selected disaster type is an earthquake or a volcano, and locations with lower elevations are avoided when the selected disaster type is a tsunami or flooding, wherein the suggested route does not have a specific destination; and

controlling, with the processor, the user interface to output navigation instructions for guiding the user on the suggested route in order to avoid the selected disaster type.

2. The method of claim 1, wherein the portable electronic device further comprises a compass for determining a direction in which the portable electronic device is oriented, and the method further comprises:

presenting a plurality of geographical directions to the user through the user interface of the portable electronic device and prompting the user to indicate one or more geographical directions in which the disaster is located; and

receiving one or more geographical directions selected by the user,

wherein generating the at least one suggested route for the user to follow using the route software of the portable electronic device is performed according to the selected disaster type, the current location of the portable electronic device, and the one or more selected geographical directions in which the disaster is located.

3. The method of claim 1, wherein the portable electronic device further comprises a compass for determining a direction in which the portable electronic device is oriented, and the method further comprises:

presenting a plurality of geographical directions to the user through the user interface of the portable electronic device and prompting the user to indicate one or more geographical directions in which the user wishes to travel in order to avoid the disaster; and

receiving one or more geographical directions selected by the user,

wherein generating the at least one suggested route for the user to follow using the route software of the portable electronic device is performed according to the selected disaster type, the current location of the portable electronic device, and the one or more selected geographical directions in which the user wishes to travel in order to avoid the disaster.

4. The method of claim 1, wherein generating the at least one suggested route for the user to follow comprises generating a plurality of suggested routes, wherein upon the user selecting one of the plurality of suggested routes, the portable electronic device provides navigation instructions for guiding the user on the selected route in order to avoid the selected disaster type.

5. The method of claim 4, wherein the plurality of suggested routes include routes which are labeled as being a fastest route, a highest route, and a lowest route.

6. The method of claim 1, wherein generating the at least one suggested route for the user to follow using the route software of the portable electronic device is performed according to the selected disaster type, the current location of the portable electronic device, and known current traffic conditions.

7. The method of claim 1, wherein generating the at least one suggested route for the user to follow comprises generating the at least one suggested route while avoiding locations on a path of an approaching hurricane or tornado when the selected disaster type is a hurricane or a tornado.

8. A method of providing emergency route guidance to guide users away from a disaster, the method comprising:

receiving from a user a request for emergency route guidance through a user interface of a portable electronic device, the portable electronic device further comprising a map database for storing map data including road information and elevation data, route software for creating navigation instructions for generated routes, and a position receiving device receiving position signals indicating a current location of the portable electronic device;

the user specifying a radius from the current location of the portable electronic device that the user would like to move away from,

determining the current location of the portable electronic device with the position receiving device;

presenting a list of possible disaster types to the user through the user interface of the portable electronic device;

receiving a selected disaster type from the user;

generating, with a processor of the portable electronic device, at least one suggested route for the user to follow by executing the route software of the portable electronic device according to the selected disaster type, and the current location of the portable electronic device, and the elevation data of surrounding areas, wherein generating the at least one suggested route for the user to follow comprises generating a route to guide the user away from the current location of the portable electronic device by a distance equal to or greater than the specified radius;

radius, wherein locations with higher elevations are avoided when the selected disaster type is an earthquake or a volcano, and locations with lower elevations are avoided when the selected disaster type is a tsunami or flooding; and

controlling, with the processor, the user interface to output navigation instructions for guiding the user on the suggested route in order to avoid the selected disaster type.

9. A method of providing emergency route guidance to guide users away from a disaster, the method comprising:

receiving from a user a request for emergency route guidance through a user interface of a portable electronic device, the portable electronic device further comprising a map database for storing map data including road information and elevation data, route software for creating navigation instructions for generated routes, and a position receiving device receiving position signals indicating a current location of the portable electronic device;

determining the current location of the portable electronic device with the position receiving device;

presenting a list of possible disaster types to the user through the user interface of the portable electronic device;

receiving a selected disaster type from the user;

generating, with a processor of the portable electronic device, at least one suggested route for the user to follow by executing the route software of the portable electronic device according to the selected disaster type, the current location of the portable electronic device, and the elevation data of surrounding areas, wherein when the selected disaster type is a hurricane or tornado the suggested route is substantially parallel to a path that the hurricane or the tornado is traveling toward; and

controlling, with the processor, the user interface to output navigation instructions for guiding the user on the suggested route in order to avoid the selected disaster type.
