22-Channel Traffic Signal Controller
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.

22way Traffic Signal Controller
The Smart Zebra Crossing Control Unit is the core control device of a smart illuminated zebra crossing system and is classified as intelligent traffic control equipment for public security and traffic police at intersections. Installed in an outdoor cabinet beside the roadway, 22way Traffic Signal Controller provides centralized management of illuminated paving tiles, road studs, voice prompts, and pedestrian detection modules; 22way Traffic Signal Controller enables intelligent coordination between zebra crossing lighting and pedestrian signal lights, thereby enhancing pedestrian safety and reducing the incidence of conflicts between pedestrians and vehicles. The cabinet utilizes an outdoor rainproof sheet-metal enclosure featuring high-voltage safety protection and a dust-proof, heat-dissipation design, making 22way Traffic Signal Controller suitable for all-weather outdoor operating environments at urban intersections (as shown in the figure below).
Functions of Route 22 Signal Products
Signal light timing control (basic function):Based on preset signal phases and timing schemes, the system automatically switches between red, yellow, and green lights to ensure alternating traffic flow in different directions; 22way Traffic Signal Controller incorporates yellow-light and full-red clearance safety intervals to prevent conflicts. 22way Traffic Signal Controller supports multi-time-slot scheduling schemes, automatically switching between different timing configurations during the morning peak, off-peak hours, and evening peak.
inductive control:Pedestrian crossing button: the green light is extended only when vehicles are present; when there are no vehicles, the signal automatically cycles through phases; once a pedestrian presses the crossing button, a pedestrian-release signal is triggered, reducing idle signal periods and improving traffic efficiency.
Connected version:Through network/GPS time synchronization and coordination with signalizers at multiple upstream and downstream intersections, a green wave is created; vehicles can then travel continuously on a single lane with green lights at the recommended speed, thereby reducing stops and waiting on arterial roads.Switching between multiple operating modes:Automatic normal release; yellow flashing warning (low traffic at night)Full red lockout, manual control (on-site dispatch by traffic police), dimming mode
Fault self-diagnosis and alarm:Provide real-time monitoring of signal unit groups, power supplies, and communication failures; automatically log faults and upload them to the backend; and automatically switch to safety mode when an anomaly occurs (e.g., switching to a yellow flashing mode) to prevent loss of control at intersections.
The core pain points that Route 22 signal systems can address for customers
Disorder in traffic flow at intersections, frequent conflicts between pedestrians and vehicles, and a high risk of accidents
Standardized phase-based signal release logic, red–yellow–green signal sequencing combined with a full-red clearance interval, mandatory separation of conflicting traffic flows, standardized rights-of-way for pedestrians and vehicles, and reduced traffic safety hazards at intersections.
Fixed timing is inflexible, resulting in congestion during peak hours and underutilization during off-peak periods, which leads to low traffic efficiency.
Supports multi-time-slot scheduling, with automatic switching between morning/evening peak periods, off-peak periods, and nighttime periods;
Intersection control is fragmented, making unified supervision and remote parameter adjustment impossible.
Support for networked connectivity to the traffic control platform enables remote adjustment of signal timing, switching of operational schemes, viewing of real-time signal status, and retrieval of traffic flow logs; 22way Traffic Signal Controller also facilitates centralized management of multiple intersections, significantly reducing the cost of on-site field debugging.
Harsh outdoor conditions make equipment prone to damage and necessitate frequent operation and maintenance.
The supporting outdoor protective cabinet (as shown in the figure) provides dust and rain protection, as well as heat dissipation and ventilation; the motherboard incorporates lightning protection and overvoltage protection, enabling 22way Traffic Signal Controller to withstand complex outdoor operating conditions, reduce failure rates, and extend the operation and maintenance cycle.
