Abstract
Transfer of control (TOC) from automation to the human user when an SAE Level 3 or 4 vehicle reaches its capability boundaries is a key challenge. To ensure drivers have appropriate situation awareness (SA) of the driving task before taking control of the vehicle, guidance and feedback is required. A repeated-measures study in a driving simulator exposed 60 users to four experimental conditions that varied in the level of feedback and alerts provided. These comprised (1) no SA guidance, (2) basic SA guidance, (3) enhanced SA guidance, and (4) enhanced plus SA guidance. Data from questionnaires measuring workload and usability was collected. Statistical analysis revealed that ‘SA guidance’ had a positive impact compared with ‘no SA guidance’, but human agents varied in their preference for different levels and modes of feedback and alerts provided. A case for exploring customisation of SA guidance and alerts is made.
