1. A method by a first device comprising:
periodically receiving a first message, which includes first vulnerable road user (VRU) information on a first VRU device, of a first message type for communication between a network and a device from the network;
determining a state of the first VRU device as a first state based on the first VRU information;
determining a transition of the state of the first VRU device from the first state to a second state based on a speed of the device being less than a specific threshold and a speed of the first VRU device being greater than or equal to the specific threshold;
converting the first message of the first message type into a virtual message of a second message type for direct communication between devices based on a determination that the state of the first VRU device has transitioned from the first state to the second state; and
transmitting the virtual message including the first VRU information to neighboring devices.
