Edge-Aided V2X Collision Avoidance with Platoons: Towards a Hybrid Evaluation Toolset
Ref: CISTER-TR-240404       Publication Date: 27, Jun, 2023

Abstract:
Infrastructure-brokered collision avoidance is an Intelligent Transportation Systems (ITS) application built on top of Vehicle-to-Everything (V2X) links. An edge-hosted ITS service receives information from road-side sensors (or CAM messages in V2X-enabled vehicles) and detects impending collisions where vehicles cannot sense or contact each other directly. If so happens, it issues a warning message through network-to-vehicle links. Another relevant ITS application is platooning, through which vehicles following each other closely can benefit of improved fuel economy, and that can be further enhanced through communication. In case of emergency braking in platoons, the response times of network and edge-hosted services must be minimal to ensure no collision amongst the platoon or any other road user. In this paper we present the implementation of a simulation framework tailored (but not limited) to evaluate the presented use-case. This complex and multi-layered use-case can be handled by a dedicated ITS service that leverages the sensing, radio and computing resources available at infrastructure and vehicles, and requires a realistic evaluation framework prior to deployment. Such framework is mostly based on simulation, albeit, to the extent possible, actual devices or services should be used; the present work is a step towards that hybrid setup.
