This dataset was collected within the context of the PAsCAL research project between June 2021 and September 2021 at the E-Bus Competence Centre premises in Livange, Luxembourg. Subject of the pilot was a Wizard of Oz experiment, which consisted of a modified high-capacity bus vehicle to simulate a Level-5 automated vehicle to the passengers, although the bus was operated and driven by a human driver, which was not visible to the participants. The participants experienced several malfunctions of the bus and were offered a Human-Machine-Interface (HMI), which connected them to a traffic control centre for troubleshooting. The purpose of the pilot was to evaluate whether available HMIs are able to bridge the gap to human driver support to passengers. Some of the participants were blind or partially sighted to also observe the adequacy of the solution on vulnerable travellers. In order to analyse the answers given to the questions, it is recommended to consult also the "PAsCAL WP6 Pilots Surveys" dataset, which contains all questions and possible answers.
