In this work, we showcase the potential benefit of employing opticalintelligent reflecting surfaces (O-IRS) for improving safety messagedissemination for vehicular visible light communication (V-VLC) systemsparticularly at the road intersections. Buildings, roadside structures,signboards, and other impediments commonly hinder line-of-sight (LoS)communication between vehicles at urban crossroads scenarios. We propose usingO-IRS at road intersection to improve the communication link's reliability. Wecompare the performance of proposed scheme with baseline scenarios such asoptical relay and non line-of-sight (NLOS) road reflection (NRR) aidedvehicle-to-vehicle (V2V) communication. From obtained results, it has beenshown that O-IRS offers considerable performance enhancement as compared to thebaseline scenarios. In particular, O-IRS can achieve longer communication rangeas compared to the optical relay aided V-VLC systems while ensuring desiredquality-of-service (QoS).
