This study conducted a driving simulation experiment to compare four automated driving systems (ADS) during lane change demanding situations on highways while accounting for the drivers’ gender, age, and experience. While an ADS is activated, the vehicle approaches traffic congestion on the left-hand lane. ADS-1 can reduce the speed to synchronize with the congestion. ADS-2 reduces the speed and issues an optional request to intervene, advising the driver to change lanes manually. ADS-3 offers to overtake the congestion autonomously if the driver approves it. ADS-4 overtakes the congestion autonomously without the driver's approval. Results of drivers' reaction and acceptance indicated that differences between ADS designs increase when considering the combined effect of driver's gender, age, and experience more than when the effect of each factor is considered separately. While preliminary, these findings may help us understand how ADS users' behavior can differ based on several demographic human factors.
