The invention discloses a public transport vehicle intersection priority pass control system and method based on edge computing, and the method comprises the steps: 1, receiving a bus priority pass demand, and judging whether the demand needs to carry out the priority pass control or not; 2, carrying out resource allocation on edge computing according to the requirements of priority pass control;3, obtaining a public transport vehicle intersection priority pass control scheme through edge computing; and 4, controlling the direction of the bus to be green and the conflict phase to be red according to the priority pass control scheme of the bus intersection. The edge computing technology is applied to intersection control, part or all of tasks originally executed in the cloud center can betransferred to the edge equipment to be executed, the pressure of the cloud center can be relieved, meanwhile, response time delay is reduced, data exposure is reduced, and external interference is reduced.
