The Turner-Fairbank Highway Research Center performs advanced research for several areas of transportation technology for the Federal Highway Administration. The Office of Operations Research and Development (HRDO) focuses on improving operations-related technology through research, development, and testing.
This report details continuing work sponsored by HRDO to promote the early deployment of connected-vehicle technology. Under this task order, the project team developed and tested four new plugins based on the four use cases for the Vehicle-to-Everything (V2X) Hub. This report describes these plugins, which are essential for implementing the infrastructure requirements for connected-vehicle technology and intelligent traffic systems in general. In addition, this report provides insight into the function of the new V2X Hub plugins and their uses in real-world connected-vehicle deployment. It is the project team's intent that the V2X Hub will continue to enable infrastructure owners and operators by providing a single platform that communicates with pedestrians and other vulnerable road users with mobile devices, connected and automated vehicles (including transit vehicles), or other devices from both the field infrastructure and center-based systems (e.g., traffic/transit-management center).

| 16. Abstract
The United States Department of Transportation is interested in developing individual and consolidated technologies that share safety information between road vehicles, trains, infrastructure, and mobile devices using multiple communications media. The Vehicle-to-Everything (V2X) Hub project was initiated to build a software platform to act as a network intermediary that allows for messages to be sent and received by all users in a connected system, regardless of how widely distributed the systems are or what protocols and standards these systems use to broadcast messages. Feedback and input were solicited from the early adopter community to determine which applications should be prioritized and to develop test cases and procedures. This report providesa high-level description of the V2X Hub system architecture, design, and communication protocols, as well as an overview of the hardware and software required for deployment. This report also summarizes feedback and insight from stakeholders that implemented and used specific plugins for their V2X Hub deployments. |
