Abstract: Aiming at the existing problems of signal controller based on traditional traffic control theory, the architecture and design concept of a new generation artificial intelligence traffic signal controller based on edge computing, scene-driving and traffic control resourcing were proposed. Firstly, a new concept of scene-driving and traffic control resourcing based on artificial intelligence perception and decision-making needs was proposed, so as to realize the effective combination of artificial intelligence and traffic signal control. The technical architecture of the intelligent traffic signal controller was reconstructed by introducing edge computing technology. Secondly, the hardware and software structure of traffic signal controllers were studied and designed by edge computing technology and SD (scene driven, software defined) technology. Finally, the theoretical and technical problems that needed to be solved in the next step were elaborated in detail. The research results provide basic support and research ideas for the application of artificial intelligence in the field of urban traffic control.
