Abstract

Behavioural adaptation refers to changes in user behaviour following the introduction of changes in the road-vehicle-user system. The introduction of automated driving systems (ADS) triggers changes in drivers’ perception, cognition, attitudes, performance, and the driver state as shown in a previous driving simulator study on repeated usage of an ADS (Metz et al., 2021). The present study aims at overcoming limitations associated with the driving simulator setup and replicates the study design on German public roads using prototype level 3 ADS. Three different versions of a level 3 ADS with different operational design domains (ODD) are compared in a between group design. N = 75 drivers experienced a level 3 ADS during four experimental driving sessions. The drivers were free to activate / deactivate the function as they liked and to spend driving time on self-chosen side tasks. With growing experience, the mental model of the system improves towards more realistic expectations towards system capabilities. At the same time, acceptance and perceived safety increase while stress decreases. Objective indicators of system handling are impacted by the ODD, however there are no changes with repeated usage. The results from the on-road study are compared with the results from the driving simulator and they are discussed with regard to the theory of behavioural adaptation.

期刊介绍： Transportation Research Part F: Traffic Psychology and Behaviour focuses on the behavioural and psychological aspects of traffic and transport. The aim of the journal is to enhance theory development, improve the quality of empirical studies and to stimulate the application of research findings in practice. TRF provides a focus and a means of communication for the considerable amount of research activities that are now being carried out in this field. The journal provides a forum for transportation researchers, psychologists, ergonomists, engineers and policy-makers with an interest in traffic and transport psychology.
