The Automated Vehicle Safety Consortium (AVSC) this week announced the availability of its second published best practice titled, Describing an Operational Design Domain (ODD): Conceptual Framework and Lexicon.

The best practice provides a much-needed conceptual framework and common language that all manufacturers and developers can use in defining and communicating the ODD for their automated driving systems (ADS)-operated vehicles with users.

AVSC says this framework guidance provides a starting point for transportation agencies and industry to better communicate with each other and the public about deployments, tests and operations of AVs that meet SAE Level 4 as defined by the SAE J3016 "Levels of Driving Automation" Standard.

"In order for highly-automated vehicles to operate safely on public roads, developers and manufacturers need to work from a common framework and use a common lexicon so there is consistency in their descriptions of capabilities," Dr. Edward Straub, executive director of the AVSC, said in a statement. "The guidelines in this best practice will help reduce confusion, align expectations across stakeholders, streamline communication, and ultimately take another important step forward in building public trust, acceptance, and confidence in SAE Level 4 vehicles on our roadways."

The AVSC's conceptual framework and lexicon balance the need for granularity with practical usability. This guidance and specificity are important as operators and transportation agencies develop AV technology and the supporting infrastructure.

The consortium says the lexicon includes terms related to weather-related conditions, road surface conditions, roadway infrastructure, operational constraints such as rush hour and zone restrictions, road users, non-static roadside objects, and connectivity. To build the lexicon, the AVSC leveraged relevant industry standard terms and definitions and consolidated from many sources such as The American Association of State Highway and Transportation Officials (AASHTO), the National Weather Service (NWS), and the National Oceanic and Atmospheric Administration (NOAA).
