Method development for studies at test tracks of long-term behavioral adaptation in automated vehicles
Project A-0018 within SAFER's Open Research at AstaZero Program.
Driver behavior in highly automated vehicles is mainly explored in driving simulators or at test tracks in experiments that only last for 15-90 min. This limits the ability to explore drivers’ behavioral changes over time, which is crucial in the context of control transfer between drivers and automated vehicles. The goal of the study is to explore methods that enable long-term studies of drivers’ behavioral adaptations in highly automated vehicles. For this, the study will utilise a Wizard of Oz technique to study interactions between drivers and automated vehicles, e.g., at control handovers. A methodology that enables collection of both objective and subjective data will be developed and applied at the test track AstaZero.
A method utilizing Wizard of Oz technique that enables studies of drivers' behavioural adaptations over time in highly automated vehicles (e.g., at handovers). An approach to collect and combine qualitative and quantitative data in order to understand drivers' behavioural adaptations. Knowledge on drivers' behavioural adaptations in the context of intent communication in handover scenarios. With this knowledge RISE Viktoria will further strengthen its position as an independent research organisation in the automotive domain at national, and international level.
Method development. Arrange a set of workshops and pilot tests at AstaZero with the aim to develop a systematic approach that can be used to study long-term effects of behavioural adaptations in automated vehicles. In particular, approaches suitable for investigation of issues on transfer of control between the automated vehicle and the driver will be explored. To enable this, the Wizard of Oz technique will be implemented in a test vehicle provided by Volvo Cars Corporation. Various tools for collection of subjective and objective data will be explored, including the eye tracking tool provided by SmartEye.
Method validation. The method will be tested in a scenario with a limited number of test participants to examine long terms effects regarding transfer of control between the driver and the automated vehicle. The rural road at AstaZero will be used for testing.
