At present, the realization of the networked control of signal machines and the construction of intelligent traffic signal control systems have become the first choice for many cities to achieve traffic congestion relief. However, the signal control systems often require professionals to operate due to numerous parameters and complex applications. The biggest pain point of the traffic signal system is "heavy construction, light application". This paper introduces a simple innovative application method of intersection labeling control. Starting from the characteristics and common problems of intersections, triggering conditions, operation logic, output parameters are the basis of control, so as to realize a simple and fast signal control method.
