ABSTRACT: In this paper, we propose parallel wireless optical communication with an LED traffic light as a transmitter and a high-speed camera as a receiver. Today, it is proposed to use visible light communication for road-to-vehicle communication, which assists drivers by providing various information. It is also proposed to use LED traffic light as its transmitter. Thus in this paper, we propose a road-to-vehicle communication system using a high-speed camera. In our proposing system, we receive data by capturing the transmitter with the high-speed camera, making it possible to recognize each LED separately. We have examined communication speed and conducted experiment of parallel data transmission under laboratory condition.
