CENTRISDynamic Junction Control Unit

Everything Under Control

CENTRIS is a multifunctional Dynamic Junction Control Unit that enables junctions to be managed according to traffic conditions, signal timings to be adjusted, and field equipment to be monitored remotely.

Thanks to its high processing power, it evaluates data received from different traffic sensors in real time and runs control algorithms developed specifically for each junction.

Dynamic Junction Control Unit

Compatible with the VIERO Vehicle Counting System, loop detectors, RFID systems, magnetometers, and other sensors that generate density data, CENTRIS adjusts traffic signal timings according to vehicle count and traffic density data. It thereby contributes to reducing vehicle waiting times at traffic signals and managing junction flow more effectively.

CENTRIS operates in integration with the MANGO Traffic Management Center. Signal programs prepared through MANGO can be uploaded remotely to CENTRIS, the operating status of the junction can be monitored, and necessary interventions can be performed from the center.
