Intersection Safety via Infrastructure Sensor-Sharing

Intersections are a hotspot for traffic fatalities and injuries globally, with nearly a quarter of U.S. traffic fatalities and half of all injuries occurring in these high-risk areas. To address this, the 5GAA has developed a technical report on the ‘InterSafe Service,’ an approach leveraging infrastructure sensor-sharing to increase intersection safety for all road users, especially Vulnerable Road Users (VRUs) like pedestrians and cyclists.

This report explores key use cases, system requirements, and deployment options for integrating Vehicle-to-Everything (V2X) communication technologies with infrastructure sensors. It outlines a framework for developing interoperable, standardised solutions that can operate efficiently within existing Intelligent Transportation System (ITS) spectrums. Crucially, the service is designed to deliver safety benefits even during the early stages of V2X adoption, when only a fraction of vehicles are equipped with these technologies.

The document also provides recommendations for global standards organisations, such as SAE International and ETSI, to expedite the development of system-level profiles. By fostering collaboration across stakeholders, the InterSafe Service has the potential to significantly reduce intersection-related incidents and accelerate the adoption of life-saving technologies worldwide.
