Scenario Creation (replace refs with hyperlinks)
Scenario Creation entails acquiring the necessary data and knowledge to create a scenario, while Scenario Formatting involves structuring the scenario using, e.g., a scenario description language such as ASAM OpenSCENARIO XML in combination with ASAM OpenDRIVE, or a schema based on the StreetWise domain model (de Gelder et al., 2022) or MetaScenario (Chang et al., 2022). Finally, Scenario Storage entails storing the formatted scenario in a searchable scenario database (SCDB). This component also includes the SUNRISE federated layer for accessing individual scenario databases. However, those wanting to access a scenario from the SCDB provider may do so directly also. Please note that the scenario creation, and scenario formatting processes take place within each SCDBs; within the scenario storage, the SUNRISE federated layer is introduced to link individual SCDB into the federated layer. The requirements identified within T5.1 illustrate the entry barriers for a database to be connected to the SUNRISE federated layer.
Please note, the scenario creation takes place in individual SCDB, therefore the information here are for references, however from safety assurance point of view, the scenario creation process is an integral part. As mentioned earlier, scenarios can be created using two different approaches: data-based, and knowledge-based [ref]. Taking the Safety PoolTM scenario database [ref] as an example, which UoW has been developing and maintaining, it contains scenarios generated using eight different methods which belong to the two approaches. Within our surveyed framework/guidance documents, as indicated in Section 5 and also the appendix, EU ADS Act [ref], FRAV VMAD [ref], CertCAV [ref] mention scenario creation approaches from both data-based and knowledge-based; SAKURA [ref] mainly uses data based scenario creation approach; Streetwise [ref] also incorporate real world data combined with sampling methods to create scenarios; VVM [ref] documents a data based scenario generation approach from drone database.
