Infrastructure Owner Operators Guiding Principles for Connected Infrastructure Supporting Cooperative Automated Transportation

Cooperative Automated Transportation (CAT) envisions all stakeholders and elements of the transportation system working together to improve safety, mobility, equity, and operations efficiency through interdependent vehicle, infrastructure, and systems automation enabled by connectivity and information exchange. The concept is intentionally expansive, building on work being done among public agencies, industry, and academia to develop connected and automated vehicles and infrastructure systems to support them. It looks beyond existing, developing, and planned transportation concepts to a fully integrated system serving travelers, goods, and services.

Automated vehicles and the CAT concept are developing so quickly that the American Association of State Highway and Transportation Officials (AASHTO), Institute of Transportation Engineers (ITE), and the Intelligent Transportation Society of America (ITS America) formed a joint Task Force in 2019 to develop guiding principles for infrastructure owner/operators (IOOs) in supporting CAT. The resulting Guiding Principles (GPs) were then reviewed and approved within the three associations, with the final guiding principles being adopted by AASHTO at its Annual Meeting in October 2019.
