Abstract
A system and method for providing real-time traffic information using a wireless vehicle-to-vehicle communications network. A vehicle includes a plurality of sensors that detect other vehicles around the vehicle. The wireless communications system on the vehicle uses the sensor signals to calculate a traffic condition index that identifies traffic information around the vehicle. The vehicle broadcasts the traffic condition index to other vehicles and/or road side infrastructure units that can present the information to the vehicle driver, such as in a navigation system, and/or rebroadcast the traffic information to other vehicles. The traffic condition index can be calculated using the speed of the surrounding vehicles, posted speed limits, the distance between the surrounding vehicles and the traffic density of the surrounding vehicles.
