Summary
This report details the development of a specialized online training program designed to address the growing need for workforce education in Intelligent Transportation Systems (ITS) and vehicle-to-everything (V2X) communication technologies. The project was motivated by observations that while ITS and V2X technologies are expanding rapidly, practitioner education and awareness have not kept pace. Although the Virginia Department of Transportation (VDOT) had previously established general training for connected and automated vehicles, stakeholders identified a specific gap in knowledge regarding the underlying communication protocols and technologies. To bridge this gap, the Virginia Tech Transportation Institute (VTTI), funded by the Safety through Disruption (Safe-D) National University Transportation Center, developed a targeted curriculum to support infrastructure owner-operators, engineers, and project managers in maintaining systems and planning future implementations. The methodology focused on instructional design and content production, executed in collaboration with VDOT and the Virginia Transportation Research Council (VTRC). The process involved three primary tasks: project management, instructional design, and material production. The team first developed a content outline identifying key communication technologies, protocols, performance metrics, use cases, and data security considerations relevant to the transportation sector. This outline was expanded into a script and organized into modules, accompanied by the creation of assessment quizzes. The final production phase involved creating a 60-minute, self-paced, dual-modality online course. Materials included narrated PowerPoint slides with images, infographics, charts, and video clips, as well as audio recordings and integrated text formats to ensure accessibility. All materials were reviewed by VDOT and VTRC to ensure technical accuracy and appropriateness for the intended audience. The resulting deliverable is a 10-module training program covering topics ranging from an introduction to ITS and wireless communications to specific wired technologies and system use cases. The curriculum explicitly covers wireless technologies including Dedicated Short-Range Communications (DSRC), cellular V2X (C-V2X), cellular networks, Citizens Broadband Radio Service (CBRS), Wi-Fi, Bluetooth, and Low-Power Wide-Area Network (LPWAN). Wired technologies addressed include fiber networks, Ethernet, Universal Serial Bus (USB), RS-485, and Controller Area Network Bus (CAN Bus). Each module includes five-question quizzes, and the program concludes with a 20-question comprehensive assessment. The training was designed to be hosted on the VDOT University platform, providing interactive features such as real-time scoring and completion tracking. The significance of this work lies in its contribution to workforce development and technology transfer within the transportation sector. By providing a structured, high-level overview of current communication technologies utilized by industry providers and manufacturers, the program aims to enhance the safety and security of transportation systems through improved practitioner competence. The materials are available for public dissemination through the Safe-D website and repositories, ensuring broader access for transportation agencies and the general public. The report concludes that the training successfully addresses the identified educational gap, though it notes that future updates may be necessary as industry technologies and capabilities continue to evolve.
Key finding
The Virginia Tech Transportation Institute developed a comprehensive 60-minute online training program consisting of ten modules covering ITS and V2X communication technologies for transportation sector personnel.
