System Prototype Proposed for Vehicle Communications Based on VLC-RF Technologies Adaptable on Infrastructure

The chaotic increase in the number of vehicles and the population density makes road safety an important topic from all points of view. Urban planning and disorganization in terms of traffic efficiency and fluidization solutions cause massive traffic congestion in most cities around the world. The diversity of mechanisms and devices dedicated to the fluidization of traffic in pedestrian areas or pedestrian crossings does not offer safety to all categories of persons, here referring to the sick, elderly, children. A number of studies that have analyzed and focused on the field, offer solutions whereby a combination of vehicles and automated tools, used in conjunction with an efficient data communication type, can reduce traffic congestion problems and reduce traffic jams. Wireless communications technologies have the possibility of the dynamic and increase the security of the transmission mode. We can say that this article presents an overview. of the most important and promising technologies that can be. used in the applications dedicated to the road safety sector based on communication between cars. We propose a system prototype based on RF (Radio-Frequency) communications and VLC (Visible Light Communications) technology, thus making a promising alternative in the field. Based on these proposals, analyzes and simulations are performed on a hybrid architecture, offering results on performance evaluation of the solution.
