Today, human life is threatened by road accidents inside the vehicle especially when driving in bad weather conditions such as rainy,icy, and foggy weather. These weather conditions can be treacherous if the driver does not have enough preparation and awareness ofhis vehicle for bad weather on the road. The driver must have preparations such as slowing down, increasing the following distance,keeping the light ON, breaking gently, and preparing for unexpected things happening on the road; all these need more attention onthe road. Therefore, most vehicles today have a controller (ECU) (Engine Control Unit); it is like the human brain; the main job of theECU is to collect the vehicle's information from sensors such as tire pressure, engine, brake, light, airbag, and collision. However, theimportant information for our project comes from collision sensors fixed on the front and back bumpers of the vehicle. Thedevelopment of technology such as Visible Light Communication (VLC) is widely used for high-speed wireless data communicationwith a high data rate for different applications. The VLC technique is less affected by bad weather conditions and transmits dataof different types over long distances at high speed. Therefore, this technology is used for numerous promising applications and isfound suitable for outdoor and indoor applications. This article project uses visible light techniques to exchange information for allvehicle sensors with data centers through road sign grid networks. The main source of a transmitter and receiver by using a matrixLED light fixed on the Headlight or tail-light of the vehicle. In addition, all this information collected from different vehicles isprocessed in the Network Road Data Centre. The result will be a signal of attention and order to the Driver and ECU of the vehicle toreduce the speed and stop the vehicle. Finally, a new VLC transmission method is proposed in this article for communication betweenvehicles and environments to make intelligent roads and save human life. Moreover, the design uses VLC encoded by complexmodulation techniques called recursive optical OFDM with a low FPGA power consumption, leading to an increase in vehicleresponse and a reduction in accidents compared with other methods.
