Smart control system for LEDs traffic-lights based on PLC: design and transmitter implementation

摘要

The scope of this paper is to present the initial steps in the implementation of a smart traffic light control system based on powerline communications (PLC) technology. The system operates with traffic lights implemented with LED technology, that has a number of advantages as compared to traditional incandescent lamps. The proposed system makes use of the transmission media to communicate different traffic light groups with a central regulator in order to exchange information about the status of the lighting elements. From the regulator, the status and operation of the traffic light group can be monitored and changed according to traffic conditions and time. The proposed system provides a reduction in the long term maintenance costs, and can be used to remotely control the operation of traffic lights.
