The workshop participants stressed the need for standards, interoperability, skilled workforce, data sharing, and coordinated implementation. They emphasized the importance of the USDOT taking the lead in driving these initiatives forward to realize the benefits of digital infrastructure in transportation. The success of these use cases will be measured by various factors, including safety improvements, economic growth, reduced emissions, and enhanced equity in transportation.

The report goes a level deeper on two important, specific use cases: connected vehicle data and traffic signal integration.

  • Standardization: There’s a need for standardization in data exchange and integration to ensure interoperability and efficiency across the digital infrastructure. The U.S. Department of Transportation (USDOT) is urged to collaborate with existing national standardization programs and industry stakeholders to develop data standards, especially at the ‘system of systems’ layer.
  • Connected Vehicle Data: Standardizing connected vehicle data is essential for improving safety and system efficiency. Key actions include promoting collaboration among stakeholders, ensuring data privacy and security, developing infrastructure, and incentivizing data sharing and exchanges. The report suggests the formation of a national committee to represent diverse perspectives in this sector.
  • Traffic Signal Integration: Integrating traffic signals for safety and optimization requires standardization, data sharing guidelines, and infrastructure development. OEMs are encouraged to share data with transparent guidelines and legal agreements. Innovative funding mechanisms are proposed to support traffic signal integration.
  • Digital Infrastructure Architecture: The report discusses the concept of a shared data layer as part of a reference architecture. This shared data layer would facilitate data exchange and communication between various systems and stakeholders, enabling the development of innovative applications for transportation. The report emphasizes the need for cybersecurity standards, real-time situational awareness, and the role of 5G communication in data exchange.
  • Challenges and Considerations: Several challenges are identified, including the need for continuous updates to standards, managing data privacy and security, and balancing data collection with individual privacy rights. The report also stresses the importance of engaging technology providers, addressing funding issues, and considering the time-sensitive nature of data integration.

The report outlines several key points and recommendations for a comprehensive plan for the development and implementation of digital infrastructure:
