The invention discloses a V2X message forwarding method for roadside intelligent networking equipment, and belongs to the field of intelligent traffic. The method comprises the steps of establishment of a forwarding information base, adjacent station detection, message forwarding control and the like. The forwarding information base provides static information configuration and dynamic data storage functions for the forwarding system so as to be used by an adjacent station detection process and a message forwarding control process; the adjacent cell detection is used for exchanging position information between a local station and an adjacent station so as to achieve the purpose of accurately recording the position information of station equipment; and message forwarding control: synthesizing the static configuration information of the forwarding information base and the dynamic data detected by the adjacent station, determining forwarding parameters of the message, and forwarding the V2X message. The invention mainly solves the problems that the V2X communication distance is short, and the V2X communication in a non-line-of-sight scene cannot meet the vehicle communication requirement, so as to improve the coverage range of the V2X communication.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to a V2X message forwarding method for roadside intelligent network-connected equipment. Background technique [0002] Dedicated short-range communication (V2X, Vehicle-to-Everything) is a wireless communication application technology that realizes information sharing between vehicles and vehicles, vehicles and people, and vehicles and roads. Realize various applications such as road safety, traffic efficiency, and information services. Interconnection must be achieved between vehicles of different manufacturers, and between vehicles and the road infrastructure within the area within which they can reach. [0003] V2X communication is a wireless short-range communication technology with limited communication distance. For some special events in roadside information messages, such as hazard avoidance prompts, suggested speed and other information, the vehicle needs to be i...
