Visible Light Communications (VLC) represent an emerging technology which uses the solid state visible light to provide wireless data transfer as an addition function to lighting. In vehicular applications, the use of VLC is motivated by the wide deployment of LED sources in traffic lights, street lighting and vehicle lighting systems, ensuring the technology a widespread distribution at an efficient cost. Recent studies indicate that communication of safety data between vehicles or between vehicles and traffic infrastructures provide the means to considerably improve the safety and efficiency of the road transportation system. Although there is a high potential, the early state of VLC and the numerous challenges arise reliability questions regarding the suitability of the technology in automotive applications. 

In this context, this project aims at developing, implementing, and experimentally test a high-performance VLC system aimed for vehicle safety applications, focused on providing the optimal tradeoff between robustness to optical noise, communication distances and able to support the mobility imposed by the usage in vehicular applications. So, unlike most of the existing works which investigate this issues by analytical and by simulation means, this project proposal is focused on a product-orientated approach, with VLC prototypes tested on real vehicles and in mobile conditions, contributing this way to the deployment of this technology.
