Big Five personality and ADS

Abstract

Background

Automated vehicles are here now, available for everyone, and with that, everyone starts to want one too. But not everyone likes to drive automatically, or at least in this way. How can we personalize automated driving systems (ADS)? One way is by investigation drivers’ personality. For a large-scale simulator experiment, participants have been recruited by means of the Big Five Inventory (BFI; John, Donahue, & Kentle, 1991; John, Naumann, & Soto, 2008). Together with a demographics questionnaire, asking about (among others) experience with ADS, some interesting initial results can be presented on the differences between people in relation to ADS experience.



Methods

Participants were recruited at the Centraal Bureau voor Rijvaardigheidsbewijzen (CBR) and the Algemene Nederlands Wielrijders Bond (ANWB), among others. Requested to fill in an online questionnaire on demographics, manual- and automated driving experience and exposure, and the BFI, participants were categorised in one of the five traits. The initial data from these questionnaires will be presented here.



Results

A total of 85 participants (52 male) were recruited, aged between 23-66 years (M[SD]=46.0[10.3]), with 43.5% having experienced driving with ADS. A total of 11 participants were classified as Open (7 male), 18 as Conscientious (10 male), 13 as Extravert (8 male), 17 as Agreeable (12 male), and 26 as Neurotic (15 male). Men had driven more with ADS than women (1k-5k versus <1k), and those who had more ADS experience were older, or Agreeable women. Also a significant negative correlation with education and driving experience was found, except for Open drivers.



Conclusions

Results combined suggest tech-lover stereotype of rich older men favouring ADS. Furthermore, agreeable women drove more with ADS than agreeable men, which appears to be an odd outlier. The same goes for Open drivers, who do not follow the same trend as the other traits in relation to driving experience against education level: due to their intellectual curiosity? More research is needed; therefore, more participants are being recruited for this study. An update will be presented.
