Abstract

In this paper, we provide simulated channel models reflecting practical conditions for the usage of visible light communications (VLC) in intelligent transportation system (ITS). Practical vehicular LED Head Lamp and Street Lamp considering the lighting regulation for transportation is used to design ITS scenario based on VLC. We model vehicle-to-vehicle (V2V) and vehicle-to-infra (V2I) communication links in two usage scenario (crossroad and metropolitan scenario) by using CATIA V5 tool. Then, measurements for VLC channel modeling are gathered by using Ray-Tracing scheme with commercial LightTools software. From the obtained channel impulse response in both scenario, we found that VLC channels for ITS has dominant multiple LOS links and less multipath components. However, we can notice that V2I link and metropolitan scenario show more dispersive multipath channel characteristics than others.
