Abstract
As technological development towards connected and automated vehicles (CAVs) continues to
rise, addressing the challenges associated with their integration is crucial, especially regarding
public acceptance. This study explores the acceptability of CAVs, focusing on their potential role
in enhancing safety and justice within the transport system. Semi-structured interviews were
conducted with a diverse participant group, including 18 car drivers (aged 20–79, M = 48.3, SD
= 18.77) and 12 pedestrians (aged 18–61, M = 36.0, SD = 12.94). Thematic analysis was
employed to identify and contextualise factors influencing CAV acceptability, encompassing
usefulness, ease of use, effectiveness, affordability, and social acceptability. Results emphasised
safety as a top priority for both drivers and pedestrians. Trust and system reliability were also
common concerns, varying with participants’ roles and transport experiences. Both drivers and
pedestrians identified cost and economic benefits as significant barriers to CAV acceptance.
Moreover, shared apprehensions about justice in adopting CAVs acknowledged the imperfections
inherent in technological advancements. Participants supported CAVs but raised concerns about
potential harm to vulnerable road users. Both car drivers and pedestrians expressed concerns that
introducing CAVs could exacerbate existing injustices these road users face. This study offers
valuable insights into how individual differences influence CAV acceptability, contributing to
understanding their preparedness to adopt advanced automotive technologies.
