The invention provides a parameter self-learning signal control method based on cloud edge collaboration, and solves the problems that traffic signal algorithm control seriously depends on traffic parameter configuration and excessively depends on training samples, and real-time all-weather and full-scene application is difficult to realize. The method mainly comprises the steps that traffic holographic trajectory data are collected, and edge induction signal control is carried out; holographic sensing control parameters are extracted from the holographic data through a parameter self-learning method; a cloud edge cooperative control architecture is established, parameter self-learning data interaction is performed, and traffic signals are controlled in real time. Traffic states of all phases are judged through holographic data, a parameter self-learning method is adopted, a cloud edge cooperative control system is established, all-weather and all-scene application of traffic control is achieved, and the method has the advantages of being high in real-time control capacity, adaptive to various traffic flow conditions and traffic scenes, capable of avoiding calculation power and trial and error cost needed by parameter learning and the like.
