Traffic Signal Controller

Rich functionality, easy operation, and perfect compatibility***fine-tunes traffic signal timing programs based on real time traffic volume, maximizing the efficiency of traffic signals at intersections***the built-in modem allows the system to communicate on a real-time basis with advanced traffic signal systems. ***uses the data collected by up to 32-channel loop detectors on traffic volumes by direction and roadway to achieve optimal signal control. ***can house various detectors such as video detectors, ultrasonic detectors, microwave detectors and laser sinsors***user-friendly graphical mmi display***48 outputs are provided for efficiently controlling the signal system at busy intersections. ***offers full interoperability with existing national police agency standards compliant controllers and other electronic controllers.

Work lampOptional unitsLoop detector: wires imbedded in the road pavement which produce an electromagnetic field and recognize the passing or presence of vehicles through changes in thd field. GPS-unit: receives time signals from the global positioning system (GPS) satellite metwork and automatically synchronizes the traffic signal controller with them. Provides digital time information and long-range receptionRi-uni (wireless time signal receiver) : receives time signals from FM broadcasts and automatically sets the time of thd traffic signal controller. Interconnects a number of controllers at intersections. Lazer sensor-unit (non-emvbedded) : this distance sensor light (990 nm range) , detects an object passing anywhere in the preset range, and generates an electric trigger signal. It recognizes exactly when a vehicle has entered thd scan area, and continues to produce output signals as long as the vehicle is in thd scan area, allowing the user to determine whdther the vehicle is in the area and how long it is there
