Abstract

A method and system for providing a traffic warning for a predictive route and a suggestive rerouting for a motor vehicle is disclosed. The method includes steps of retrieving traffic information for roadways included in a predictive travel zone, including traffic incidents. The method also includes steps of calculating a suggestive reroute that reroutes the user around a traffic incident and continuing on a roadway within the predictive travel zone.

Claims

1. A method of providing navigation information for a motor vehicle, comprising the steps of:

retrieving, in a navigation system in the motor vehicle, navigation information associated with a current location and a heading of the motor vehicle;

determining, in the navigation system, a predictive travel zone associated with a predetermined shape around the current location of the motor vehicle and extending in a direction associated with the heading of the motor vehicle;

retrieving, in the navigation system, traffic information corresponding to the predictive travel zone, the traffic information including a traffic incident associated with at least one of a primary roadway and a secondary roadway within the predictive travel zone, the primary roadway being associated with the current location of the motor vehicle and the secondary roadway intersecting the primary roadway and being associated with the heading of the motor vehicle;

providing, via the navigation system, an alert to a user of the motor vehicle if the traffic incident is located within the predictive travel zone;

providing an option to the user to reroute the motor vehicle around the traffic incident;

receiving, in the navigation system, a selection from the user to reroute the motor vehicle around the traffic incident; and

upon receiving the selection from the user to reroute the motor vehicle, the navigation system calculating a new route around the traffic incident to a predictive future location on the secondary roadway beyond the traffic incident, if the traffic incident is associated with the secondary roadway; and

wherein the navigation system determines that the user intends to travel towards the predictive future location on the secondary roadway based on the selection from the user to reroute the motor vehicle.

2. The method according to claim 1, wherein the predetermined shape of the predictive travel zone is based on a type of road associated with at least the primary roadway and the secondary roadway.

3. The method according to claim 1, wherein the predetermined shape of the predictive travel zone is based on a shape of the primary roadway.

4. The method according to claim 1, wherein the predetermined shape of the predictive travel zone varies based on a speed of the motor vehicle.

5. The method according to claim 1, wherein the predetermined shape of the predictive travel zone varies based on an average speed associated with at least the primary roadway and the secondary roadway.

6. The method according to claim 1, wherein the alert further comprises a show map option, a dismiss option and a suggest reroute option.

7. A method of providing a suggestive reroute around a traffic incident for a motor vehicle, comprising the steps of:

calculating, in a navigation system in the motor vehicle, a predictive travel zone associated with a predetermined shape around a current location of the motor vehicle and extending in a direction associated with a heading of the motor vehicle;

retrieving, from the navigation system, navigation information corresponding to one or more roadways included in the predictive travel zone;

determining, in the navigation system, a predictive route using the retrieved navigation information, the predictive route being associated with a potential future location of the motor vehicle;

identifying, in the navigation system, a primary roadway along the predictive route, the primary roadway being associated with the current location of the motor vehicle and on which the motor vehicle is traveling;

identifying, in the navigation system, at least one secondary roadway along the predictive route, the at least one secondary roadway intersecting the primary roadway and being associated with the heading of the motor vehicle;

retrieving traffic information corresponding to the predictive travel zone from the navigation system, the traffic information including one or more traffic incidents associated with one or more of the primary roadway and the at least one secondary roadway;

providing, via the navigation system, an alert to a user of the motor vehicle if a traffic incident is located within the predictive travel zone;

receiving, from the navigation system, a request from the user to reroute the motor vehicle around the traffic incident;

upon receiving the request from the user to reroute the motor vehicle;

calculating, in the navigation system, a reroute around the traffic incident and back on the primary roadway, if the traffic incident is associated with the primary roadway;

or

determining, by the navigation system, that the user intends to travel towards a predictive future location on the secondary roadway based on receiving the request from the user to reroute the motor vehicle;

calculating, in the navigation system, a suggestive reroute around the traffic incident that takes into account the predicted future location on the secondary roadway beyond the traffic incident if the traffic incident is associated with the secondary roadway; and

providing the suggestive reroute to the user.

8. The method according to claim 7, wherein the step of providing an alert to a user includes providing at least one of an audio and a visual indication.

9. The method according to claim 7, wherein the alert may be provided within an entertainment portion of an interface associated with the motor vehicle.

10. The method according to claim 7, wherein the alert may further include a show map option, a dismiss option and a suggest reroute option.

11. The method according to claim 10, wherein the step of receiving a request from the user further includes receiving a selection of the suggest reroute option from an interface associated with the motor vehicle.

12. The method according to claim 11, wherein the interface includes a touch screen.

13. The method according to claim 10, wherein the alert further includes an option to view a map portion of an interface associated with the motor vehicle.

14. A method of providing a suggestive reroute around a traffic incident for a motor vehicle, comprising the steps of:

receiving, in a navigation system in the motor vehicle, motor vehicle information from at least one sensor associated with the motor vehicle, the motor vehicle information including at least a current location and a heading of the motor vehicle;

determining, in the navigation system, a predictive travel zone associated with a predetermined shape around the current location of the motor vehicle and extending in a direction associated with the heading of the motor vehicle;

retrieving, in the navigation system, navigation information corresponding to one or more roadways included in the predictive travel zone;

retrieving, in the navigation system, traffic information corresponding to the predictive travel zone, the traffic information including one or more traffic incidents associated with at least one of a primary roadway and a secondary roadway within the predictive travel zone, the primary roadway being associated with the current location of the motor vehicle and the secondary roadway intersecting the primary roadway and being associated with the heading of the motor vehicle;

providing, via the navigation system, an alert to a user of the motor vehicle if a traffic incident is located within the predictive travel zone;

receiving, at the navigation system, a request from the user to reroute the motor vehicle around the traffic incident;

upon receiving the request from the user to reroute the motor vehicle, the navigation system determining if the traffic incident is associated with the primary roadway or the secondary roadway; and

if the traffic incident is associated with the secondary roadway, calculating a suggestive reroute around the traffic incident to the secondary roadway that takes into account a predicted future location on the secondary roadway, and providing the suggestive reroute to the user;

wherein the navigation system determines that the user intends to travel towards the predictive future location on the secondary roadway beyond the traffic incident based on receiving the request from the user to reroute the motor vehicle.

15. The method according to claim 14, wherein the navigation information is received at the motor vehicle from a service provider.

16. The method according to claim 14, further including calculating a reroute around the traffic incident and continuing back on the primary roadway, if the traffic incident is associated with the primary roadway.

17. The method according to claim 14, wherein the alert further comprises a show map option, a dismiss option and a suggest reroute option.

18. The method according to claim 14, wherein the traffic information is received at the motor vehicle from a traffic database.

19. The method according to claim 14, wherein the traffic information is real time traffic information.
