The proposed framework of 80 cars connects through VLC/RF within 6 lanes road. The car-to-car communication system comprises a framework of 80 cars within six lanes road with three lanes in one direction and the other three lanes in the opposite direction. Green arrows represent single-hop VLC, red arrows represent multi-hop VLC, and yellow arrows represent multi-hop VLC to overcome the field of view problem, while yellow lightening represents single-hop RF. The selected road distance is 25 km. Each car has a variable speed from 60 to 100 km
