Real time traffic aide
First Claim
1. A traffic system for providing real-time traffic information from one vehicle to other vehicles, said system comprising:
- a plurality of sensors provided on the one vehicle, said sensors detecting surrounding vehicles and traffic around the one vehicle; and
a wireless communications system responsive to sensor signals from the sensors, said wireless communications system including a controller that calculates a traffic condition index identifying the traffic around the one vehicle and broadcasting the traffic condition index to the other vehicles, said controller calculates the traffic condition index using a vehicle speed factor of a speed of the surrounding vehicles and a vehicle distance factor of a distance between the surrounding vehicles, wherein at least one of the other vehicles re-broadcasts the traffic condition index to other vehicles.

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.
