5G-SAFE is a Tekes Challenge Finland project of VTT and FMI, aiming at supporting wide-scale implementation and usage of advanced road weather services with enhanced 5G networking capabilities and service enablers. The new services will assist drivers to cope better with challenging arctic weather conditions in short-term, and supporting the development of self-driving vehicles in long-term. The services will be delivered to vehicles via a heterogeneous 5G network environment, incorporating optimized communication network selection, local processing (e.g. mobile edge computing), information aggregation, and information security. Two pilot constructions will be used for testing and demonstrating the solutions.

The project will identify a set of relevant use cases for the 5G infrastructure in the context of improving road safety in arctic traffic weather conditions. Based on the use cases, a set of prototype services will be defined and developed. The advanced vehicular services are envisioned to make use of vehicle camera data and supporting measurements from the vehicle (e.g. friction data). This data is transmitted in real-time via 5G into a specific service cloud or a service core, together with other data available from supporting sources, for instance, the research road weather station (RWS) data of FMI. The collected data is combined to the meteorological “service billets” (e.g. Snowdrift index currently based on fixed RWS and long-haul weather data and forecasts). As a result, accurately location-based real-time services are generated, and again by exploiting the 5G network, delivered back to the vehicles, ultimately benefiting these services the most. VTT has the main responsibility of 5G infrastructure, while FMI focuses on the services.
