Presentation on blind-spot accident data and work on the development of a test cycle to assess the effectiveness of blind-spot countermeasures to reduce the risk of VRU collisions.

Based on GRVA-25-08, the document addresses blind spot accidents involving right-turning trucks and bicycles. It distinguishes between warning systems requiring driver reaction time and automatic brake intervention systems. The document notes that information systems with low intensity have low annoyance and low risk of deactivation, while high-intensity warnings risk driver annoyance and deactivation. It describes a specific scenario at approximately 15 km/h where a truck brakes after a turn has started with a bicycle detected at high confidence. The document indicates that next steps in safety regarding blind spot accidents should involve automatic brake intervention and suggests future discussion of UN R151 in GRVA.
