Method for improving V2X communication reliability

The invention discloses a method for improving V2X communication reliability. The method comprises the steps that: a first-level roadside unit acquires a V2X equipment ID corresponding to a vehicle; registering the id of the V2X equipment into a first-level road side unit id list of a region where the RSU road side unit is located; judging whether a vehicle-mounted V2X terminal computing unit of the vehicle runs normally or not; opening a message permission to the vehicle registered in the id list; selecting a corresponding road side unit to perform information interaction; and when the vehicle leaves the region, closing the message sending and message receiving authority of the region. According to the method, hierarchical management is carried out on the V2X roadside units; the road sideunits of different levels bear information data of different contents; communication limitation is carried out between different types of roadside units and vehicles in different regions; the efficiency of resource allocatio
