Influence factors and improving strategies of perceived safety - an on-road study with L2 autonomous driving.
Perceived safety (PS) and trust are important factors that influence the adoption of autonomous driving. In order to study the factors influencing PS and the possibility of real-time monitoring, an on-road experiment with L2 autonomous driving with 30 participants was conducted. Participants experienced autonomous driving functions as co-drivers and rated PS through video replays. Physiological data were recorded during the experiment and analysed afterwards. It was found that PS significantly reduced during events of hard braking and bumps, whereas it was high during congestions and hard-turning events when speed was relatively lower. Analysis of geolocations and environmental data around the vehicle showed that tunnels, terrain and traffic complexity would impact PS. Physiological data showed a significant negative correlation between electromyogram (EMG) of the lower limb and PS. Through post-experiment interviews, technical and human-computer interaction (HCI) measures that are expected to improve PS are proposed.
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
