What is the Internet of Vehicles scenario for realizing vehicle-to-road communication?

Analysis of test questions: Vehicle and Road (V2I): On-board equipment communicates with roadside infrastructure (such as traffic lights, traffic cameras, roadside units, etc.); Vehicle-to-vehicle (V2V): Vehicle-to-vehicle communication through on-board terminals; People (V2P): Vulnerable traffic groups (such as pedestrians, cyclists, etc.) use user equipment (such as mobile phones, laptops, etc.) to communicate with in-vehicle devices; Vehicle and Network (V2N): In-vehicle devices communicate with in-vehicle devices through the access network/core network.
