Scenario (vehicular automation)

For other uses of "Scenario", see Scenario (disambiguation).

In the field of vehicular automation a scenario denotes a sequence of snapshots of the environment and the actions of a vehicle. Scenarios are created to represent real-world situations and are used for development, testing, and validation purposes.^[1][2]

Standards

Definition	Source
"description of the temporal relationship between several scenes ... in a sequence of scenes, with goals and values within a specified situation, influenced by actions ... and events"	ISO 21448:2022(en), 3.26[3]
"sequence of scenes ... usually including the automated driving system(s) .../subject vehicle(s) ..., and its/their interactions in the process of performing the dynamic driving task"	ISO 34501:2022(en), 3.4[4]

Operational design domain

According to ASAM's OpenODD concept paper, scenarios are related to operational design domain. However, they are not the same. Defining the appropriate behavior of actors within an ODD creates a scenario that is not dependent on any ODD definition.^[5]

History

In 2022, Netherlands Organisation for Applied Scientific Research announced scenario-based safety validation of self-driving trucks in cooperation with Torc Robotics.^[6]
