Vehicle-to-everything (V2X) communication is seen as an enabler of high-density platooning as part of more environmentally friendly future transportation systems. Indeed, in high-density platooning, trucks are able to reduce their overall fuel consumption. Compared to platooning systems exclusively based on sensors, V2X enabled platooning systems can drive smaller inter-vehicle distances. They are then able to achieve this fuel consumption reduction thanks to the decreased air drag. It has been shown that the performance of the application is dependent on the performance of the communications system. The application therefore needs to be aware of the maximal tolerable communication degradation that keeps the platoon safe considering its driving parameters. In this article, we derive the relationship between the maximal tolerable packet losses, measured as the packet inter-reception time, and the intervehicle distance. We first study the relationship between these parameters through the analysis of simulation data. We then derive a functional link by fitting different statistical models. Finally, we apply the resulting models to packet inter-reception time measurements obtained in simulation of platoons supported by IEEE 802. 11p driving through varying surrounding traffic densities.
