The level 3 automation vehicles provide time for drivers to participate in a non-driving task when vehicle automation is on. However, the vehicle requests the driver to take control of the vehicle when the system reaches its limitations. Many researchers have studied different hand-over procedures, and the effect on take-over time and driving performance. There is limited research on analyzing the driver's transitions during the transfer of control in an automated vehicle. The goal of our research work is to find out the order of a series of transition stages that a driver goes through during take-over in an automated vehicle. Sub goals were to find out the take-over time and interleaving time by varying take-over request times. Additionally, the influence of take-over request time on transition stages is evaluated. An experimented was conducted with 15-sec and 30-sec take-over request times. Take-over request time includes pre and emergency audio alerts. Pre alert time is varied in two take-over request times scenario by having 8 sec of constant emergency alert time. From the results, two orders of series of transition stages are found, naming Interleaving order and Suspension order. The percentage of occurrence of interleaving order during take-over is found 80 % in 30 sec take-over request time. Maximum mean take-over time 21.06s (S.D 7.81) is found in a 30-sec scenario Interleaving order. The driver's interleaving time is 18.72s in the 30-sec scenario, whereas 9.28s in the 15-sec scenario. From the results, we observe that the different take-over times affect the driver's order of series of transition stages and the time duration between stages during take-over.
