Abstract :
In intelligent transport systems (ITS) with a purpose to decrease traffic accidents, vehicle information and communication system (VICS) has been in practical use in Japan. It is expected to place light emitting diode (LED) illumination into practical use as a future light source. Also in road illumination, utilization of the LED illumination is considered. We propose a visible light communication system, which uses LED road illumination. First, we propose the shape of the LED road illumination, which fulfills the standard specification of road illuminations in Japan. We can change the light source of the existing road illumination by using the proposed LED illumination. Next, we consider carrying out vehicular communications using this LED road illumination. It was proven that vehicular communications is possible through numerical analysis and excelled the present VICS system in using LED road illumination.
