A device may include a memory storing instructions and processor configured to execute the instructions to register client devices to receive Vehicle-to-Everything (V2X) messages, including at least one Road Side Unit (RSU) configured to broadcast messages to vehicles using Wireless Local Area Network (WLAN) signals or using cellular wireless signals over a PC5 interface. The processor may be further configured to receive a V2X message; determine a geographic area associated with the received V2X message; determine a message type for the received V2X message; identify a set of client devices located in the identified geographic area and subscribed to receive V2X messages of the identified message type; select a subset of client devices, of the identified set of client devices, based on geographic or situational relevance; and send the received V2X message to the selected subset of client devices, including the at least one RSU.
