In this paper, we compare two prevailing overlay schemes for 802.11p, Slotted and Token-based Overlay for Platooning (TOP), focusing on performance in different vehicle densities in a critical braking scenario. We additionally propose GS (Grouped Slotted) which extends Slotted to be an inter-platoon overlay, rather than intra-platoon using grouping to further reduce the number of packet collisions per second and improve the inter-vehicle distances. The results reveal that overall, TOP is safer than Slotted, although it causes a significantly higher number of packet collisions per second. The results further demonstrate that GS outperforms all compared schemes, representing a better solution as it achieves the lowest packet collision rates while ensuring better inter-vehicle distances.
