Testing activities typically serve the purpose of verification (have I built the system right?) or validation (have I built the right system?). Within all validation activities related to AD, the safety validation is the most essential one. Therefore, the safety validation will be a major part of testing activities. However, before testing can start it is essential that a clear definition of what “safe” means for development of an ADF, exists within the company. Once this definition is available, what should be proven within the safety validaiton process can be then defined. In this process it is important that this definition of “safe” is then cross checked with external advisors.
Inputs for the definition of safety validation can be found, for instance, in the work of the German funded project PEGASUS (Mazzega, J. et al. (2019)) and in similar projects, such as V&V Method (Germany), SAKURA (Japan), HEADSTAR (EU) as well as in the Safety First for Automated Driving” (SaFAD) white paper (Wood, M., et al) and its following ISO activities that are addressing the development of a safe ADF (ISO/TR 4804 (2020), ISO/CD TS 5083).

Main Question
Does a definition of “safety validation” exist?
Sub-Questions
- Is there a definition of what “safe” means?
- Has the interpretation of “safe” been discussed with outside stakeholder?
