Study suggests that drivers using advanced driving assistance systems (ADAS) may need more training on these systems.

Simulator study of driving behaviors with ADAS.

Background (Show)

Lesson Learned

Drivers with stronger mental models (i.e. understanding) of ADAS performed significantly better compared to drivers with weaker mental models.

Drivers with stronger mental models were faster to react to changing conditions, faster to deactivate the ADAS, and maintained better gap distances compared to drivers with weaker mental models.

This difference in performance was likely due to differences in understanding how the ADAS might function under challenging road conditions and awareness of ADAS limitations. Drivers should potentially be provided more training or guidance on how their vehicle’s ADAS functions and what its limitations, are to improve safety of ADAS. Although, who should provide this training is an open question.
