Development and Piloting of Novel 5G-Enabled Road Safety Services

The development of 5G is taking steps forward to solve the communication challenges of the future. One of the main application areas to benefit from 5G is intelligent traffic and vehicular communication. This paper discusses the recent advances in the development and piloting of novel road weather and safety services. The services considered in the paper exploit extensive vehicular observation data, of which transmission is enabled by a 5G communications architecture. The purpose of the services is to provide enhancements to road users, road maintenance operations as well as to 3rd parties. Furthermore, low latency 5G networks will enable future automated driving functionality, considered in the paper as well. The paper presents use cases and a generic system architecture for the envisioned service concepts. In addition, selected results obtained from testing the services in real vehicular and 5G test network environments are presented.
