The invention provides a control method and system for a high-priority vehicle passing task edge node. The method comprises the following steps: receiving an edge node execution task sent by cloud control; judging whether a first edge node task needs to be executed or not according to the edge node execution task; if the first edge node task does not need to be executed, entering a path saturation control state; receiving the high-priority vehicle passing information sent by the second edge node, sending an edge node access request instruction to a high-priority vehicle terminal, and entering a node traffic control state; receiving a first edge node passing instruction sent by the high-priority vehicle terminal, and sending high-priority vehicle passing information to a third edge node; and quitting the edge node to execute the task. According to the intersection high-priority vehicle passing control method based on edge calculation, a powerful emergency traffic decision-making scheme can be provided for traffic managers, and a solution is provided for emergency vehicle priority passing.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a control method and system for an edge node of a high-priority vehicle passing task. Background technique [0002] As we all know, most of the traditional urban traffic control models adopt a centralized architecture scheme. The existing technology transmits all traffic-related data through the network, centralizes them to the cloud computing center and uses its super computing power for processing, but a large increase Intelligent transportation devices generate a large amount of data transmission in real time, which will put a lot of pressure on the network bandwidth. For example, a self-driving vehicle generates 4TB of data a day, all of which cannot be uploaded to the cloud for processing. [0003] At the same time, with the enrichment of application types, the real-time requirements of intelligent transportation services in the future will increase. Taki...
