Summary
This report evaluates driver reactions to new vehicle technologies designed to enhance safety, comfort, and mobility across different age groups. The research addresses the critical challenge of public trust and appropriate usage of semi-autonomous systems, particularly for older drivers who may face challenges adapting their mental models of vehicle operation. The study specifically assessed two technologies: a semi-autonomous parallel parking assistance system (Active Park Assist) that steers the vehicle while the driver controls throttle and brake, and a cross-traffic warning alert system that detects encroaching vehicles when backing out of parking spaces. The experimental design involved two separate studies, each utilizing a sample of 42 participants. The subjects were distributed evenly across three age groups (20s, 40s, and 60s) and balanced by gender within each group. Participants underwent training and practice sessions before performing parking maneuvers. The study employed a within-subject design where participants performed multiple parking tasks both with and without the assistive technologies. Data collection included objective physiological measures, specifically heart rate recorded before, during, and after parking maneuvers, as well as traditional self-report ratings of stress levels. The findings indicated that the semi-autonomous parallel parking system significantly reduced driver stress. Participants reported significantly lower stress levels (p = .025) and exhibited an average heart rate reduction of 12.6 beats per minute (p < .001) when using the assistive technology compared to manual parking. This reduction in physiological arousal was consistent across all gender and age groups. Notably, heart rate proved to be a more sensitive measure of stress than self-report data. While the cross-traffic warning system showed suggestive trends toward stress reduction, these differences were not statistically significant (p > .05). However, behavioral observations revealed that drivers were more likely to appropriately stop and yield to approaching vehicles when the cross-traffic alert system was active, potentially lowering accident risk. The significance of these results lies in the confirmation that assistive technologies can effectively reduce driver anxiety, even with limited prior experience. The study hypothesizes that detailed orientation and guided training played a crucial role in facilitating participant adaptation and trust in the technology. Although overall ratings were positive, some individuals experienced issues with the systems, highlighting the need for further analysis into why certain users struggle with new technologies. Understanding these barriers is essential for improving technology adoption and maximizing the safety and stress-reduction benefits of advanced vehicle systems for drivers of all ages.
Key finding
Using the semi-autonomous parallel parking system lowered drivers' average heart rate by 12.6 beats per minute versus manual parking and significantly reduced self-reported stress.
