SYSTEM AND METHOD FOR EXCHANGING POSITIONING INFORMATION BETWEEN VEHICLES IN ORDER TO ESTIMATE ROAD TRAFFIC
First Claim
1. A method for estimating traffic conditions based on positioning information exchanged between vehicles using wireless communication, the method comprising:
- receiving positioning information repeatedly broadcast by at least one vehicle, the positioning information for each vehicle comprising;
information related to a current location of the vehicle; and
information identifying the vehicle;
calculating based on at least two successive locations of a same identified vehicle, a current speed and a current direction for the vehicle; and
estimating current traffic conditions based on current location, speed and direction of identified vehicles.
