A self-control method applicable at the intersection of car-based networking environment

A method suitable for controlling a self-intersection of the vehicle based networking environment, which belongs to the field of vehicle networking technology. This method makes full use of the vehicle networking advantages, provide real-time status information of the vehicle to the roadside unit, which on the whole road network first abstraction model, the calculated dynamic priority traffic streams each strand; then according intersection specific characteristics, to establish the optimal phase phase sequence model, in order to achieve optimum phase phase sequence current intersection, so that the high-priority traffic can be preferentially flow through the intersection, while ensuring the release of the single maximum traffic. The method without a large number of embedded sensors, which not only reduces the cost of construction of the control system of the city, but also beneficial to maintain and upgrade traffic control system. Accurate real-time control of traffic flow, vehicle status, greatly changed in the past traffic control system is seriously lagging behind, get even less information is error.
