Intelligent transport systems and visible light communication applications. An overview

The context of the Internet of Things and the growing use of mobile devices have demanded wireless communication alternatives, complementary to radio frequency. As a promising alternative, optical wireless communication has emerged, due to significant deployments in solid-state lighting technology. Light-emitting diodes have been adopted in many domains, both indoors and outdoors. In this case, they can be seen in traffic lights, vehicles, and public lighting. Since this lighting component is the base of the visible light communication, there are many opportunities to be explored regarding intelligent transport systems, some of them, already proposed or developed worldwide. As presented in this article, visible light communication has the potential to provide a significant contribution to the communication demands in the intelligent transport systems scenario.
