Use Cases and Communications Architecture for 5G-Enabled Road Safety Services

Abstract

Efficient and safe road network is an essential requirement for a modern society. This paper presents use cases and architecture for novel 5G-enabled road safety services. The use cases aim at preventing traffic accidents, optimizing road maintenance, and enabling autonomous driving by delivering focused time-critical services to vehicles and their drivers as well as to road operators and 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> party organizations. The services rely on real-time sensor and IoT data collected from the vehicles and roadside infrastructure. The paper proposes a generic system architecture for the realization of the use cases and studies the implementation of vehicular data communications within the architecture. The resulting data management framework is evaluated by comparing selected protocol implementations in order to find the best practices for its realization.
