Abstract:
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.
