ESRIUM
EGNSS-enabled smart road infrastructure usage and maintenance for increased energy efficiency and safety on European road networks

ESRIUM is a multi-national project with the common goal to set up a service to foster greener and smarter road usage, road maintenance, and to increase road safety. The key innovation will be formed by a homogeneous, accurate and recent digital map of road surface damage and road wear. ESRIUM’s core proposition is a data platform, which hosts highly detailed EGNSS-referenced map data of road damage and associated safety risks at centimeter-level resolution. Further addressed as “road wear map”, it will contain unique information, which is of value to multiple stakeholders: road operators will be able to lower the road maintenance effort by optimal planning. Further, road operators will be able to lower road wear and increase traffic safety especially for heavy vehicles. Considering the market introduction of partly automated truck fleets, the precise track of these vehicles can be adjusted by communicating precise routing recommendations in- and cross-lane. Truck fleet operators following these recommendations can receive tolling benefits, and increase the general safety for their vehicle fleet. Especially with the increasing levels of autonomy, systems will utilize infrastructure support to handle the requirements of the automated driving task and additional external requests. In ESRIUM, these opportunities are addressed by utilizing CITS infrastructure and EGNSS based localization in planning the trajectories of such automated vehicles. Key to the ESRIUM innovation is a precision localization service, which provides reliable locatization information of road damages and of the vehicles using the roads. Considering a European-level businesscase, only Galileo may provide such a service in homogeneous quality, even at very remote locations on the European continent.
