Driver's situation awareness during supervision of automated control - comparison between SART and SAGAT measurement techniques

Systems enabling to drive automatically are being introduced on the market. When using this technology, drivers are in need for interfaces which support them with supervision of the automated control. Assessment of Situation Awareness (SA) which drivers are able to gain while using such interfaces, is important. Based on comparison between SART and SAGAT measurement techniques within a simulator study, the test set-up presented in this paper suggests to be successful in providing a coherent test-bed with relevant situations to assess the level of SA drivers gain when involved in supervision of automated control and while using different types of feedback.
