Abstract

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.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control, and in particular relates to an edge computing-based priority traffic control system and method for bus intersections. Background technique [0002] The intersection is a key node in the urban road network. The traffic composition is complex. It is the place where vehicles and pedestrians gather, turn and evacuate. However, it is also a place where traffic congestion and traffic accidents occur frequently. The bottleneck that restricts the increase of urban road traffic capacity. Traditional intersection control relies solely on the cloud center, and the detector data needs to be uploaded to the cloud center. After the cloud center optimizes the control, it feeds back the control plan to the signal machine on the roadside. This control method relies solely on the cloud center and has a large transmission delay. It is suitable for task control with a large amount of calculation and low ...
