System and method based on short range wireless communications for notifying drivers of abnormal road traffic conditions
First Claim
1. A method executed in a vehicle, for predicting traffic conditions based on traffic information exchanged using short range wireless communications, between vehicles moving in opposite directions, the method comprising:
- successively recording traffic information based on traffic encountered by the vehicle;
sending the traffic information to vehicles moving in the opposite direction;
receiving traffic information from vehicles moving in the opposite direction;
consolidating the traffic information received from the vehicles moving in the opposite direction; and
predicting traffic conditions based on the consolidated traffic information;
wherein the traffic information for each vehicle comprises;
an identifier of the vehicle;
an indication of a speed of the vehicle; and
data related to traffic successively encountered by the vehicle,wherein the data related to traffic successively encountered by the vehicle comprises at least one traffic record, each traffic record comprising;
a time or a time interval from a reference time;
an indication of a speed of a vehicle moving in the opposite direction at the reference time; and
an indication of a distance from the vehicle to the vehicle moving in the opposite direction at the reference time.
