Investigating the Effects of Automated Driving Style and Drivers’ Driving Style on Drivers’ Perception of Automated Vehicle Driving Indicators
SessionST7 - Vigilance and Driving
Perception and Performance
DescriptionWith advances in automated vehicles (AV), it is increasingly important to determine how the driving indicators of AV should be designed to enhance driver trust and acceptance. The present study investigated drivers’ perception of AV driving indicators in two styles and their influence on driver trust and acceptance. Thirty-two participants (16 aggressive drivers and 16 defensive drivers) ride with either an aggressive AV or a defensive AV. Results indicated that drivers could differentiate the aggressiveness of AVs’ speed, stopping distance, and right turn angle with different automated driving styles. The inappropriateness of AV driving indicators was associated with perceived faster speed, larger or smaller deceleration, and shorter stopping distance, which jointly influenced driver trust and acceptance of AVs. Moreover, defensive drivers perceived aggressive AV indicators to be more inappropriate than defensive AV indicators, but such effect was not observed for aggressive drivers.
