5G NR V2V Communications for Enhanced Collision Avoidance: The EEBL Application Case

This paper investigates the role of Vehicle-to-Vehicle (V2V) communications in enhancing road safety, with a focus on the Emergency Electronic Brake Lights (EEBL) application. We analyze a scenario with an abruptly decelerating vehicle on a highway, and we derive the conditions for trailing vehicles to either prevent collisions or maintain a safe following distance. We simulate the scenario using ns-3, with a focus on Fifth-Generation (5G) New Radio (NR) to provide the V2V communication needed for the EEBL application. The findings indicate that the use of the EEBL application over NR V2V significantly enhances road safety by preventing forward collisions that would otherwise occur due to delayed human driver reactions.
