The U.S. DOT ITS Joint Programs Office has initiated a new project, RSU (Roadside Unit) Standardization, for which stakeholders representing public and private sectors as well as individuals, are invited to participate.
The project purpose is to develop and publish an RSU standard that defines the key capabilities and interfaces an RSU must-support to ensure interoperability for state and local infrastructure owner/operators (IOO). The first version of this standard should focus on leveraging existing U.S. DOT investments to more rapidly develop and publish the standard utilizing the Systems Engineering Process (SEP) and ensuring the standard supports future evolutionary updates.
This proposed standard incorporates relevant user needs, requirements and design elements of the RSUs defined in the RSU Specification 4.1, and NTCIP 1218 Object Definitions for RSUs, and validates it through outreach to the real-world RSU deployments such as the Connected Vehicle (CV) Pilots programs, and the Signal Phase, and Timing (SPaT) Challenge.

Following the SEP, project development will include a Concept of Operations (ConOps), System Requirements (SyRS or Functional Requirements), System Design Details, and associated SEP walkthroughs, as well as a hardware and application software reference implementation. The project will result in a standard that demonstrates consensus standards development processes, and has a 24-month period of performance ending September 18, 2021.
Stakeholders should anticipate that up to 15 web-enabled conference calls and three face-to-face meetings within the United States are to be held during the life of the project.
Stakeholders with the following areas of expertise or interest are invited to participate:
- RSU hardware and/or software design, manufacture, integration, operation.
- Transportation Infrastructure hardware and/or software design, manufacture, integration, operation (since infrastructure and RSUs are expected to communicate).
- Vehicle communication hardware and/or software design, manufacture, integration, and operation (since vehicles and RSUs are expected to communicate).
- Software and/or hardware design manufacture, integration, and operation for pedestrian and other vulnerable road users.
- Participants in RSU deployments including Connected Vehicle Pilots and the Signal Phase and Timing (SPaT) Challenge.
The associations actively participating in this effort are the Society of Automobile Engineers (SAE), American Association of State Highway Transportation Officials (AASHTO), National Electrical Manufacturers Associations (NEMA), and Institute of Transportation Engineers (ITE).
