Workshop on Edge Cases for Automated Driving

Webinar: 10:30 – 12:00 | Expert workshop: 14:00 – 16:00

ARCADE is a Coordination and Support Action funded by the European Commission’s Horizon 2020 programme. Methodology is one of its topics. In the CAD Knowledge Base, ARCADE collected material for evaluation methodology. 

Edge cases are essential for validation of automated driving as they present rare situations that an automated vehicle may encounter in its lifetime. Edge cases can be seen as an essential addition to scenario databases. They may also include human behaviour aspects. 

It is not obvious how to collect edge cases: they will not be encountered in everyday driving much. A fatal accident happens every 226 million km, material damage every 300 000 km (Destatis 2016). Should we then construct them by imagination? Not all edge cases are relevant: some edge cases may be simply too rare.
