System and method for exchanging positioning information between vehicles in order to estimate road traffic
First Claim
1. A method for estimating a current traffic condition based on positioning information exchanged between vehicles using wireless communication, the method comprising:
- receiving, using a wireless communication system, positioning information repeatedly broadcast by a plurality of vehicles, the positioning information for each vehicle comprising;
information related to a current location of the vehicle; and
information identifying the vehicle;
storing, using a cartographic information repository, the positioning information for each vehicle;
calculating, using a micro-controller, based on at least two successive locations of the same identified vehicle, a current speed and a current direction for the same identified vehicle;
estimating, using the micro-controller, the current traffic condition based on the current location, the current speed and the direction of each identified vehicle; and
adjusting a sensitivity for the receiving when a quantity of the plurality of vehicles exceeds a threshold.
