Drone-based traffic control and V2X enhancements

This invention describes an apparatus for flying vehicles, like drones, that can receive and interpret virtual traffic signs in a three-dimensional airspace. It uses a radio transceiver to get messages over a V2X network, and then processes these messages to understand the state of a virtual sign. The claims specifically narrow the invention to the vehicle's ability to decode these signs, which can include instructions such as changing its elevation.
