This study aimed to verify the criteria of the driver monitoring systems proposed by UNECE ACSF informal working group and the ministry of land, infrastructure, and transport of South Korea using driving behavior data. In order to verify the criteria, we investigated the safety regulations of driver monitoring systems in a conditonal autonomous vehicle and found that the driver monitoring measures were related to eye blinks times, head movements, and eye closed duration. Thus, we tok two diferent experimental data including real-world driving and simulator-based drowsy driving behaviors in previous studies. The real-world driving data were used for analyzing blink times and head movement intervals, and the drowsines data were used for eye closed duration. In the drowsy driving study, 10 drivers drove aproximately 37 km of a monotonous highway (about 2 min) twice. The results sugested that the apropriate duration of eyes continuously closed was 4 seconds. The results from real-world driving data were presented in the other paper - part 1.
