A systematic review of older drivers in a level 3 autonomous vehicle: A cognitive load perspective

Abstract

With current advancement in technology, it is expected and hoped that even a conditional or level 3 (L3) autonomous vehicle could alleviate older adults’ mobility issues. These conditional or level 3 autonomous vehicles allow the driver to engage in non-driving task (NDRT), but, it can request the driver to assume control of the vehicle via ‘Takeover request’ when it has reached its operational limits. Considering this could be a challenging for older drivers with their declined cognitive, percep- tual, and motor capacities. A systematic review has been conducted to produce literature on their issues in a L3 autonomous vehicle. This re- view mainly focuses on older drivers’ challenges, perception of workload in AVs and takeover performance. This review is hoped to provide relevant literature on the subject and may help researchers improve and pursue research gaps identified in this paper.
