Disuse of advanced driver assistance systems (ADAS)

Area of Science:

• Human-Computer Interaction
• Automotive Engineering
• Transportation Safety

Background:

• Advanced Driver Assistance Systems (ADAS) offer potential for enhanced driving safety and efficiency.
• Underutilization of ADAS is a significant barrier, driven by frequent driver disengagement and avoidance.
• Understanding the reasons behind ADAS disuse is crucial for improving their adoption and effectiveness.

Purpose of the Study:

• To investigate the phenomenon of ADAS disuse, including situational disengagement and systematic avoidance.
• To identify key factors influencing drivers' decisions to disengage from or avoid using ADAS.
• To provide insights for designing more user-centered and effective ADAS.

Main Methods:

• Conducted in-depth interviews with drivers of SAE Level 2 automated vehicles.
• Employed thematic analysis to identify recurring themes influencing ADAS disuse.
• Examined influences across three domains: Driving task, Human factors, and Environment.

Main Results:

• Key themes influencing disuse include discomfort with system aggressiveness, lack of trust in detection, and incompatibility with driving styles.
• Environmental complexities (e.g., construction zones, pedestrian areas) and legal/moral responsibility also contribute to disengagement.
• Drivers' sense of control, knowledge, and trust significantly impact their interaction with ADAS.

Conclusions:

• Adaptive, user-centered ADAS designs are needed, focusing on trust, transparency, and context-sensitive behaviors.
• Addressing barriers to ADAS use can lead to safer and more consistent adoption.
• Improved ADAS design can foster driver confidence and facilitate integration into future mobility solutions.
