Meta-Analysis on the Impact of Different Channel Loads on Takeover Performance in Autonomous Driving under Non-Driving Tasks

Abstract Under conditions of high automation, drivers’ excessive engagement in non-driving related tasks can severely impact their takeover ability, posing a significant threat to road safety. Therefore, it’s essential to explore the channel resources occupied by non-driving related tasks to enhance driving safety. However, many studies have merely categorized different types of tasks in experiments without clarifying the relationship between the tasks and the channel resources they occupy. To determine whether different channel loads under non-driving related tasks have varying impacts on autonomous driving takeover performance, a meta-analysis was conducted on literature retrieved from January 2021 to January 2024. The results indicate that tasks occupying visual, auditory, motor, and cognitive channel resources during takeover all affect takeover performance. Among these, cognitive channel resource occupation significantly reduces takeover efficiency, followed by motor and auditory channels, with the visual channel having the least impact.
