Patent Images
1. A method in a data processing system in a first vehicle for managing traffic information using peer to peer connections, the method comprising:
- identifying a traffic situation;
responsive to identifying the traffic situation, generating a traffic data packet, wherein the traffic data packet includes a traffic information, and an area of influence, the area of influence comprising an area in which the traffic information included in the traffic data packet will be useful to another vehicle; and
transmitting the traffic data packet to the another vehicle using a peer to peer connection based on a location of the first vehicle with respect to the area of influence.

Abstract
A method, apparatus, and computer instructions for managing traffic information in a data processing system in a vehicle using peer to peer connections. A traffic situation is identified. A traffic data packet is generated in response to identifying the traffic situation. The traffic data packet includes traffic information and an area of influence. A traffic data packet is transmitted to another vehicle using a peer to peer connection based on a location of the vehicle with respect to the area of influence.
