Saving Lives with connectivity: Accelerating V2X Deployment Program Grant Awards - Maricopa County

Maricopa County DOT will engage private and public agency partners to lead a largescale deployment of V2X technologies, relying primarily on 5.9 GHz communications, to connect 750 physical and virtual roadside units to an estimated 400 vehicle onboard units targeting transit, emergency, and freight fleets. The project will deploy Emergency Vehicle Preemption, Vulnerable Road User detection, Transit Signal Priority, and Freight Signal Priority applications in the Cities of Phoenix, Tolleson, Avondale and unincorporated Maricopa County, as well as along ADOT’s US 60. The project will utilize an enhanced version of USDOT’s V2X Hub, which employs the 5.9 GHz spectrum along with SCMS-enabled access to adjacent unlicensed Wi-Fi, conformant to all relevant FCC regulations and in compliance with V2X standards.

Maricopa County DOT will also utilize a mobile 5G edge computing network and Intelligent Message Platform to connect virtual roadside units to onboard units and municipal and state infrastructure at 75 intersections, demonstrating interoperability between the 5.9GHz ITS spectrum and cellular network platforms. Furthermore, the deployment will demonstrate multi-carrier interoperability through the implementation of a virtual private cloud connection between one carrier’s Mobile Edge Computing (MEC) and a 2nd carrier’s cloud platform.
