The invention discloses an intersection pedestrian-vehicle-road cooperation early warning system and method in an Internet of Vehicles environment. The system comprises a pedestrian early warning subsystem, a roadside subsystem, an edge computing subsystem, a vehicle-mounted subsystem and a communication subsystem, wherein the pedestrian early warning subsystem is used for collecting pedestrian information in real time and carrying out information interaction with the edge computing subsystem through the communication subsystem; the roadside subsystem is used for processing the received information and carrying out early warning on pedestrians and vehicles; the edge computing subsystem is used for calculating and analyzing the pedestrian information and the vehicle information transmitted by the communication subsystem and feeding back a calculation result to the other subsystems through the communication subsystem; and the vehicle-mounted subsystem is used for sensing vehicle information in real time, receiving data, which includes the running speed, the acceleration, the course angle and the coordinates, of each sensor of the vehicle, and performing information interaction with the edge computing subsystem through the communication subsystem. According to the invention, cooperative early warning of pedestrians, vehicles and roadside devices is realized.
