This paper discusses system design considerations concerning the use of visible light communication (VLC) concepts in road traffic control systems. A simple traffic set-up model has been analyzed in order to optimize various important design parameters. This optimization is based on the gain variation over 100 m transmission range. This approach will help to specify the needed gain for the receiver in the complete set-up in order to further increase the coverage area. It will also allow important simplifications at the front-end design level.
