Vehicular platooning is gaining adoption due to its benefits in fuel efficiency, road capacity, and driving stability. Vehicular platooning, which relies on low-latency and highly reliable vehicle-to-vehicle links, can naturally benefit from visible light communication (VLC) owing to its short-range, high-bandwidth, and low-interference characteristics. However, when vehicles travel on curved roads, changes in relative geometry and limited field of view (FoV) often lead to intensified intra-platoon interference. We propose an angle diversity receiver (ADR)-enhanced VLC architecture for platooning. A system model that integrates ADR geometry, VLC channel characteristics, and signal-to-interference-plus-noise ratio (SINR) analysis is developed and evaluated via OpticStudio non-sequential ray tracing with realistic vehicle/roadway geometries, material properties, and FoV constraints. ADR suppresses interference and improves reliability across inter-vehicle spacings, curvature radii, and platoon sizes; relative to a single photodetector, ADR yields an average median SINR gain of 10.27 dB on curved roads. These results indicate the feasibility of ADR-enabled VLC for practical platoon deployment in complex road environments.
