Visible Light Communication Based Traffic Information Broadcasting Systems

Abstract

Traffic safety information broadcast from traffic lights using Visible Light Communication (VLC) is a new cost effective technology which can draw attention to drivers to take necessary safety measures. This paper presents a VLC broadcast system considering LED-based traffic lights. It discusses the conceptual methodology for integrating traffic light road side unit (RSUs) with impending intelligent transportation systems (ITS) architecture. Results from a case study of VLC system for information broadcast are also presented.
