SAE J3216™ Standard Provides Clarity to Support Advancement of Full Automation
WARRENDALE, Pa. (April 21, 2020) – SAE International published SAE J3216™ Standard: Taxonomy and Definitions for Terms Related to Cooperative Driving Automation for On-Road Motor Vehicles. SAE J3216 builds on the SAE J3016™ Standard and aims to eliminate confusion, provide clarity, and offer a foundation for the advancement of vehicle automation technologies with terms, definitions and taxonomy focused on Cooperative Driving Automation (CDA), a key building block that supports all levels of automation.
“CDA sits at the intersection of two important transportation technologies, automation and connectivity, and helps enable benefits, such as cooperative intersection and traffic management applications that reduce travel times and/or improve road operations by coordinating the movement of multiple vehicles in proximity to one another,” said Shawn Kimmel, vice-chair of the SAE International On-Road Automated Driving (ORAD) Committee. “The development of a common language helps enable discussions between automobile manufacturers, technology companies and infrastructure stakeholders to work together to achieve industry goals.”
The SAE J3216 Standard describes machine-to-machine (M2M) communication to enable cooperation between vehicles with driving automation features engaged, other road users, and infrastructure owners and operators, such as traffic signals and work zones. The cooperation supports or enables performance of the Dynamic Driving Task (DDT), and is defined as four classes, A through D, based on increasing amount of cooperation entailed in each successive class: Status-sharing, Intent-sharing, Agreement-seeking, and Prescriptive. Ultimately, cooperation among multiple participants and perspectives in traffic help improve safety, mobility, situational awareness and operations.

“As an industry convener, SAE is uniquely positioned to bring together industry and infrastructure to create an agreed upon language through which CDA can safely evolve,” said Keith Wilson, technical program manager at SAE International. “As the need for CDA increases with the realization of all levels of automation, the J3216 Standard has considerable potential impacts on traffic, operations and safety in the world of automation.”
