We propose a analysis and measured data depend on distance for visible light communication based on high speed camera at intersection for ITS. In this paper, the communication between high-speed camera and a LED rear lamp is approached using LED rear lamp as the transmitter, and high-speed camera as the receiver. The LEDs in the transmitter are emitted with 4000Hz and the images of those emitting LEDs are captured with 8000fps by a high-speed camera for conducting asynchronous communication method. And experimental results using appropriate images and figures showed the effectiveness for the proposal.

We propose the vehicular visible light communication system using LED headlamp for ITS. In this paper, the communication between photo-detector and the LED headlamp is approached using LED headlamp as the transmitter, and photo-detector as the receiver. The LEDs in the transmitter are emitted using I-4PPM(inverse 4-pulse position modulation) method and those emitting LEDs are captured by a photo diode for conducting synchronous communication method. Also, this system is accessible on daytime. Experimental results using appropriate images and figures showed the effectiveness for the proposal.
