Summary

This document, titled *Vehicle-to-Everything (V2X) Deployer Resource*, serves as a comprehensive guide produced by Noblis Inc. for the U.S. Department of Transportation’s Intelligent Transportation Systems Joint Program Office. It addresses the need for standardized, practical information to support state and local agencies in deploying V2X technologies, which enable vehicles to communicate with each other, roadside infrastructure, and vulnerable road users. The motivation stems from the potential of V2X to prevent crashes, save lives, and improve transportation efficiency and sustainability. As regulatory certainty regarding the 5.9 GHz ITS radio band has increased, many agencies have moved from pilots using Dedicated Short-Range Communications (DSRC) to operational deployments using direct Long Term Evolution-V2X (LTE-V2X). The document aims to accelerate this transition by providing a "resource of resources" for both novices and experienced practitioners. The content is structured as a strategic planning and implementation guide rather than a traditional empirical study. It synthesizes existing standards, regulatory frameworks, and deployment experiences. The document covers V2X fundamentals, including key terms, stakeholder roles, message sets, and application use cases such as safety warnings and traffic advisories. It details the technical landscape, comparing short-term communication technologies like LTE-V2X with longer-term options like 5G NR-V2X, and outlines the regulatory environment, specifically the Federal Communications Commission’s licensing rules for the 5.9 GHz band. Furthermore, it provides a six-track strategic planning process for agencies, covering vision development, readiness assessment, team preparation, project scoping, scheduling, and outreach. It also addresses critical operational aspects, including procurement strategies, funding sources from the Bipartisan Infrastructure Law, cybersecurity requirements via the Security Credential Management System (SCMS), and data management frameworks. Key findings and resources include a mapping of approved Roadside Unit (RSU) sites and a summary of FCC waivers granted for LTE-V2X operations, indicating significant deployment intent across 32 state licensees and 22 other organizations. The document identifies specific V2X applications and assesses their deployment readiness, highlighting safety and mobility use cases. It provides detailed guidance on the project development lifecycle, from assessing needs and planning to design, build, test, operate, maintain, and evaluate. Specific resources are cataloged for interoperability, scalability, and performance measurement, including evaluation checklists and business case frameworks. The text emphasizes that interoperability is critical for market acceptance and effective connectivity across state boundaries. The significance of this resource lies in its role as a central repository for V2X deployment knowledge, reducing barriers for agencies seeking to implement connected vehicle systems. By consolidating technical details, regulatory guidance, and strategic planning tools, it supports the USDOT’s goal of achieving "Interoperable Connectivity." The document facilitates the transition from experimental pilots to scalable, operational V2X systems, ensuring that deployments are secure, interoperable, and funded appropriately. It serves as a foundational reference for transportation agencies, industry partners, and policymakers aiming to enhance situational awareness and safety through connected vehicle technologies.

Key finding

The document provides a consolidated guide of V2X deployment strategies, technical fundamentals, and resources to support state and local agencies in implementing interoperable connected vehicle systems.
