Ettifos, a leading provider of C-V2X solutions, announced the successful completion of real-world V2X tolling demonstrations on March 26 in North Carolina.

The demonstrations, in collaboration with Audi and Kapsch TrafficCom, validated low-latency, standards-based communication between Ettifos' V2X-AIR onboard unit (OBU) and Kapsch's commercially deployed roadside units (RSUs). The results confirm robust interoperability across a multi-vendor ecosystem under real-world operating conditions.

Conducted as part of the OmniAir Consortium V2X Tolling Workshop, the demonstrations were designed to show real-world tolling using direct sidelink (PC5) Vehicle-to-Infrastructure communication based on standardized V2X protocols.

Demo 1: Audi, Ettifos and Kapsch – Seamless Vehicle-Integrated V2X Tolling

This demonstration showcased a before-market implementation of V2X tolling within an Audi vehicle equipped with Ettifos' V2X-AIR OBU.

The Ettifos OBU established continuous PC5-based communication with Kapsch's RSUs as the vehicle traversed the tolling zone, instantly processing standardized V2X tolling messages and displaying acknowledgements on the Audi in-vehicle display.

This scenario validated Ettifos' V2X-AIR OBU as a device that is not only fully compatible with V2X tolling standards and services, but also seamlessly integrates with OEM services.

In addition to all the safety and efficiency services provided by V2X, V2X tolling is an important and scalable service that enables OEMs to offer drivers a secure and seamless in-vehicle payment system.

Demo 2: Ettifos and Kapsch – Plug-and-Play Aftermarket V2X OBU for Tolling

The second demonstration highlighted Ettifos' standard-compliant and ready-to-deploy aftermarket V2X OBU, V2X-AIR, which supports V2X safety, efficiency, and tolling services..

The dashboard-mounted OBU received and decoded V2X messages broadcast from Kapsch's RSUs, dynamically processing tolling events and Traveler Information Messages (TIM) in real time. These were visualized through Ettifos' application interface, providing immediate driver feedback on tolling transactions and relevant road warnings.

This implementation demonstrated how V2X tolling can be rapidly deployed across existing vehicle fleets prior to commercial OEM integration.
