Can set up multiple time periods and multiple programs manually, induction, stepper control, command centers and other real-time adaptive control work. Modular structure, the system has a strong adaptability. Has a special control function: The system can be based on the actual traffic situation, the command center for an order for special traffic control; Green Wave Control: Before performing the guards, fire, ambulance, rescue and other tasks, each on its route at traffic lights vehicle reaches the intersection of the time on the green, to ensure that vehicles unimpeded. Control by the central controller implementation. Single point of control: each intersection by a traffic signal lights controlled independently. Induction Control: loaned vehicle detectors, traffic automatically adjusted according to the release time. Flash Control: lights flashing yellow light at a certain frequency to warn vehicles and pedestrians or tips. Traffic Control: According to the intersection traffic demand, issue a command from the command center manually simulated traffic signal control method for traffic control. Stepping Control: Intersection with special specific requirements, traffic anomalies, stepping through the signal button to make the release time is more reasonable.
