A necessary condition for the effective integration of automated vehicles in our daily lives is their acceptance by passengers inside and pedestrians and cyclists outside the automated vehicle. 119 respondents experienced an automated shuttle ride with a ‘hidden steward on board’ in a mixed traffic environment in Berlin-Schöneberg. A mixed-method approach was applied gathering qualitative interview data during the ride and quantitative questionnaire data after the ride. Responses were classified into three main categories: (1) Perceived safety, (2) interactions with automated shuttles in crossing situations, and (3) communication with automated shuttles. Respondents associated their perceptions of safety with the low speed, dynamic object and event identification, longitudinal and lateral control, pressing the emergency button inside the shuttle, their general trust in technology, sharing the shuttle with fellow travellers, the operation of the shuttle in a controlled environment, and the behaviour of other road users outside the shuttle. Respondents pressed the emergency button inside the automated shuttle on 28 out of 62 test rides in order to test its behavior. They further expected to be more cautious in crossing the road before an automated shuttle due to the lack of eye contact with the human driver and a lack of trust in the behavior of the automated shuttle, and expected road users testing the automated shuttle due to the conservative driving behavior of automated shuttles. We recommend future research into the hypothesis that the acceptance of automated shuttles will be associated with the perceived safety of and their effective and intuitive interaction and communication with both passengers and other road users.

乘客对感知到的安全性以及与自动穿梭机互动的看法:与“隐藏”安全管理员的试乘研究

在我们的日常生活中有效整合自动驾驶汽车的必要条件是自动驾驶汽车内部的乘客以及行人和骑自行车的人对自动驾驶汽车的接受。119名受访者在柏林-舍讷贝格的混合交通环境中体验了“隐藏的乘务员”的自动穿梭游乐设施。应用了一种混合方法,在乘车过程中收集定性访谈数据,并在乘车后收集定量问卷数据。响应分为三个主要类别:(1)感知到的安全性;(2)在交叉情况下与自动穿梭车的互动;以及(3)与自动穿梭车的交流。受访者将其安全感与低速行驶,动态物体和事件识别,纵向和横向控制,按下航天飞机内部的紧急按钮,他们对技术的普遍信任,与其他旅行者共享班车,在受控环境中班车的运行以及班车外其他道路使用者的行为。响应者在62个测试骑行中的28个中按下了自动穿梭车内的紧急按钮,以测试其行为。他们进一步期望在自动穿梭之前过马路时会更加谨慎,这是因为与驾驶员的目光缺乏接触,并且对自动穿梭的行为缺乏信任,并且期望道路使用者对自动穿梭进行测试。自动班车的保守驾驶行为。
