High-Level Concept of Operations: Examination of The Relationships Between Transportation Systems Management and Operations Strategies and Cooperative Driving Automation

This report explores the relationships between transportation systems management and operations (TSMO) strategies and cooperative driving automation (CDA). It presents a high-level concept of operations (ConOps) in support of the CARMA PlatformSM sponsored by the Federal Highway Administration Office of Operations Research and Development. Developing this ConOps is an initial step in the current CARMASM effort to define and develop testable use cases that demonstrate how CDA capabilities can be integrated with TSMO strategies. The ConOps first discusses the traditional TSMO strategies for operating and managing the transportation infrastructure. It then identifies, at a high level, those strategies expected to be impacted by the introduction of CDA technologies. Next, from among this nexus of TSMO strategies, the ConOps focuses on four use cases–basic travel, traffic-incident management, road-weather management, and work-zone management–and explores the framework of those relationships in greater detail. The ConOps also describes whether–and, if applicable, how–CDA will impact existing TSMO use case activities. This mapping accounts for both the levels of vehicle automation and classes of vehicle cooperation.  The full report is available from FHWA at https://www.fhwa.dot.gov/publications/research/operations/20063/index.cfm
