User Requirements for Autonomous Vehicles – a Comparative Analysis of Expert and Non-expert-based Approach

Abstract

Given the rapid progress being made in the design and development of autonomous vehicles, society is reaching the situation whereby customers will be able to access a range of semi-autonomous vehicles. These vehicles have the capability to drive autonomously in certain circumstances, with minimal input from the driver, except situations when a Request to Intervene is issued. While user requirements differ across and between types of users, there is no unified set of user requirements which will be acceptable to all drivers. Motivated by the recent explosion of interest around autonomous mobility, the authors made an attempt to extract, rank and compare the requirements that should be met according to different types of users - experts and non-experts. An initial set of user requirements was obtained, recognizing that drivers will have different priorities and preferences in this most critical of handover scenarios.
