This paper studies the impact of dynamic vehicular traffic density on the signal-to-noise-ratio (SNR) and the associated bit-error-rate (BER) performance of vehicle-to-vehicle visible light communication (V2V-VLC) systems. The study uses traffic data from the M42 and M6 motorways in the UK to investigate the probability of co-existence of other vehicles in the adjacent lanes which induce interference and act as potential reflectors. The results show that the probability of co-existence of other vehicles in the adjacent lanes is lane-independent and it increases during the rush hours to 90%, while it decays to less than 10% during the off-peak and early morning hours. The inter-vehicular distance and the BER performance vary widely between different lanes and different periods of the day. The results also show that the BER performance of V2V-VLC system with non-line-of-sight (NLOS) component and with line-of-sight (LOS) component are comparable at rush hours. However, high BER values are predicted during the off-peak hours for NLOS components of the channel.

“…The effect of vehicle misalignment could be also mitigated based on the integration of context and environment-adaptive techniques [ 47 , 48 ]. In this case, an adaptable FOV can be used [ 41 ].…”

“…On average, such systems provide reliable middle-range links while supporting tens to hundreds of kilobits per second data rates [ 23 , 26 , 27 , 28 , 29 , 44 ]. Since the performances of automotive VLC systems are influenced by a wide range of factors, an adequate solution would be to use environment or context-adaptive VLC architectures [ 47 , 48 ], which evaluate the existing circumstances and determine an optimal trade-off for each communication parameter. Although remarkable progress has been made in addressing the main issues affecting the automotive VLC system performances, most of these challenges remain active topics of interest, as their further improvement is still being researched [ 34 ].…”

The use of visible light communications technology in communication-based vehicle applications is gaining more and more interest as the research community is constantly overcoming challenge after challenge. In this context, this article addresses the issues associated with the use of Visible Light Communications (VLC) technology in Vehicle-to-Vehicle (V2V) communications, while focusing on two crucial issues. On the one hand, it aims to investigate the achievable communication distance in V2V applications while addressing the least favorable case, namely the one when a standard vehicle rear lighting system is used as a VLC emitter. On the other hand, this article investigates another highly unfavorable use case scenario, i.e., the case when two vehicles are located on adjacent lanes, rather than on the same lane. In order to evaluate the compatibility of the VLC technology with the usage in inter-vehicle communication, a VLC prototype is intensively evaluated in outdoor conditions. The experimental results show a record V2V VLC distance of 75 m, while providing a Bit Error Ratio (BER) of 10−7–10−6. The results also show that the VLC technology is able to provide V2V connectivity even in a situation where the vehicles are located on adjacent lanes, without a major impact on the link performances. Nevertheless, this situation generates an initial no-coverage zone, which is determined by the VLC receiver reception angle, whereas in some cases, vehicle misalignment can generate a BER increase that can go up to two orders of magnitude.

“…Future steps also include devices to be installed on the surface of cars to transmit and receive information from other vehicles at a considerable distance. Current studies offer feasible perspectives because the VLC communications realized can support the transmission and reception of information at distances of up to 300 m in ideal conditions [38].…”

Vehicle density and technological development increase the need for road and pedestrian safety systems. Identifying problems and addressing them through the development of systems to reduce the number of accidents and loss of life is imperative. This paper proposes the analysis and management of dangerous situations, with the help of systems and modules designed in this direction. The approach and classification of situations that can cause accidents is another feature analyzed in this paper, including detecting elements of a psychosomatic nature: analysis and detection of the conditions a driver goes through, pedestrian analysis, and maintaining a preventive approach, all of which are embedded in a modular architecture. The versatility and usefulness of such a system come through its ability to adapt to context and the ability to communicate with traffic safety systems such as V2V (vehicle-to-vehicle), V2I (vehicle-to-infrastructure), V2X (vehicle-to-everything), and VLC (visible light communication). All these elements are found in the operation of the system and its ability to become a portable device dedicated to road safety based on (radio frequency) RF-VLC (visible light communication).
