N2 - This paper studies the impact of dynamic vehicular traffic density on the signal-to-noise-ratio (SNR) and theassociated bit-error-rate (BER) performance of vehicle-to-vehiclevisible light communication (V2V-VLC) systems. The study usestraffic data from the M42 and M6 motorways in the UK toinvestigate the probability of co-existence of other vehicles in theadjacent lanes which induce interference and act as potentialreflectors. The results show that the probability of co-existenceof other vehicles in the adjacent lanes is lane-independent andit increases during the rush hours to 90%, while it decays toless than 10% during the off-peak and early morning hours. Theinter-vehicular distance and the BER performance vary widelybetween different lanes and different periods of the day. Theresults also show that the BER performance of V2V-VLC systemwith non-line-of-sight (NLOS) component and with line-of-sight(LOS) component are comparable at rush hours. However, highBER values are predicted during the off-peak hours for NLOScomponents of the channel.
