OmniTrust and P3Mobility give transportation agencies a secure, interoperable way to connect Network V2X services, roadside C-V2X infrastructure, and traffic-signal systems while preserving local operational control. The joint solution combines trusted credentials, standards-based message routing, mobile participation, and intersection logic to deploy Network V2X today with a scalable foundation for Direct C-V2X.
Solution Focus
Signal Priority & Preemption
Trusted Connected Mobility
Vehicle & Road User Awareness
Network & Direct V2X
OmniTrust and P3Mobility together provide an end-to-end Network V2X solution connecting vehicles, cloud services, and traffic-signal infrastructure. The combined solution integrates standards-based message routing, trusted credentials, vehicle-level authorization, and intersection processing, giving agencies an integrated solution for deploying connected-mobility applications over cellular networks.
OmniTrust’s National Mobility Interchange (NMI) routes standards-based Network V2X messages between mobile, cloud, and infrastructure endpoints. TrafficAuth-Mobile enables authorized users and vehicles to generate secure signal-priority requests over the cellular network, while P3Mobility’s V2Xnexus processes requests at the intersection according to industry standards and agency policies. TrafficAuth-SCMS provides the certificate-based trust framework, issuing and managing IEEE 1609.2 credentials and permissions while preserving agency control over traffic-signal and operational decisions.
The same solution provides the application, security, and integration foundation for agencies that choose to add Direct V2X. P3Mobility’s V2Xnexus can process messages exchanged among roadside units, onboard units, and intersection systems over the 5.9 GHz C-V2X radio interface using the same standards-based application logic and agency policies applied to Network V2X. TrafficAuth-SCMS extends the trusted credential framework to these direct communications, avoiding separate security and integration silos.
P3Mobility also provides the expertise to plan, integrate, and deploy roadside C-V2X infrastructure, giving agencies a practical path to deploy Network V2X today and add Direct V2X as operational needs, infrastructure plans, and funding evolve. Together, OmniTrust and P3Mobility support interoperable SAE J2735 message flows across Network and Direct V2X environments.
| P3Mobility | OmniTrust TrafficAuth | Joint Customer Value |
|---|---|---|
| V2Xnexus (P3Mobility intersection-side V2X software) |
|
Pairs P3Mobility’s intersection-side V2X processing with TrafficAuth trust and Network V2X connectivity to securely process signal-priority requests, interface with roadside and signal-controller systems, and coordinate vehicle-to-intersection workflows. |
| V2Xpress (Network V2X message exchange) |
|
Extends P3Mobility’s Network V2X message exchange with NMI routing and TrafficAuth-SCMS trust to securely connect vehicles, cloud services, and infrastructure over cellular networks using standards-based V2X messaging. |
| P3M Safety App (Application Logic for Mobile Apps, OBU or Vehicle Integrations) |
|
Integrates P3Mobility’s vehicle-side V2X application logic with NMI connectivity and TrafficAuth-SCMS trust to securely support standards-based signal priority, preemption, and other connected-vehicle workflows. |
| P3M Authorization Server |
|
Adds P3Mobility’s V2X service authorization with NMI connectivity and TrafficAuth-SCMS trust to securely control access to subscription-based services and enable scalable, revenue-generating V2X deployments. |
| V2X Systems Integration & Deployment Advisory |
|
Combines P3Mobility’s V2X deployment, integration, and testing expertise with TrafficAuth trust, messaging, and management capabilities to help agencies move from connected-vehicle pilots to secure, operational deployments. |
In the Maricopa County CVAZ deployment, authorized transit and freight vehicles need a scalable way to request signal priority while the roadway agency retains control over whether a request is granted.
TrafficAuth-Mobile generates an authorized, digitally signed Signal Request Message (SRM) and sends it through NMI. P3Mobility’s V2Xnexus receives the request, processes it according to industry standards and agency policies, then provides the corresponding status or response back to the vehicle. TrafficAuth-SCMS provides the certificates and permissions that distinguish authorized requesters from unauthenticated devices. The P3M Authorization Server enables signal-priority subscription services with policy-specific permissions, such as vehicle-level permissions based on time of day or level of service.
Extends signal-priority participation to secure Network V2X and mobile users while preserving local traffic-engineering policy, authenticated access, and standards-based interoperability.
Regional connected-vehicle deployments must support both cellular/cloud participants and roadside and vehicle equipment communicating directly over the 5.9 GHz safety band.
In the Maricopa County CVAZ deployment, NMI routes signed Network V2X messages between applications and infrastructure, while P3Mobility’s intersection-side software connects those workflows to Direct V2X systems. TrafficAuth-SCMS issues IEEE 1609.2 credentials to authorized direct C-V2X devices, creating a common trust model across network and radio interfaces.
Protects existing and emerging roadside investments while allowing agencies to expand participation through mobile and cloud connectivity without creating separate islands of trust.
Drivers and mobile road users need timely, trusted intersection safety information, but the data may originate from a mix of roadside sensors, traffic systems, and network-connected applications.
P3Mobility software integrates intersection and roadside data, while NMI securely distributes relevant V2X messages from that infrastructure to authorized network participants. TrafficAuth-SCMS establishes trust across participating infrastructure and devices, enabling TrafficAuth-Mobile users to receive trusted safety information and validate message origin and integrity.
For the Maricopa County CVAZ deployment, the joint solution creates a scalable foundation for vulnerable-road-user alerts and other connected-intersection safety applications using the same interoperable security and message-delivery architecture.
P3Mobility is a transportation technology and advisory company focused on moving connected-vehicle programs from pilot concepts to practical, operational V2X deployments. The company combines interoperable V2X software with deployment advisory, systems integration, grant and funding strategy, operational readiness, and business-model development for public agencies and mobility partners. Its product ecosystem spans roadside and intersection management (V2Xnexus), secure Network V2X message exchange (V2Xpress), mobile/in-vehicle applications (P3M Safety App), and authorization capabilities (P3M Authorization Server). P3Mobility has experience with public-sector and USDOT-funded connected-vehicle initiatives and supports deployments across multiple U.S. states. Together, P3Mobility and OmniTrust combine intersection-side application logic and deployment expertise with TrafficAuth trust, message routing, and mobile capabilities for an end-to-end deployment from conception to operations.
