The Route 22 Traffic Signal Controller, also known as a traffic signal controller, is the core hardware device of an urban traffic signal control system. Its primary function is to control the timing sequences of traffic light color changes at intersections based on preset control schemes or real-time traffic flow data, regulate right-of-way for different directions, ensure the orderly organization of traffic flow at intersections, and guarantee road safety and traffic efficiency.
The 22-Channel Traffic Signal Controller is located at the forefront of the intersection signal control system. It interfaces with the regional traffic control center system at the upper level and connects to peripheral devices such as traffic light assemblies, countdown timers, and pedestrian push buttons at the lower level. It serves as the critical node linking upper-level control strategies with lower-level signal outputs.
