Overall effects of non-driving related activities’ characteristics on takeover performance in the context of SAE Level 3: A meta-analysis

Abstract

Since users of Level 3 driving automation systems may engage in non-driving related activities, it is of interest to investigate effects of non-driving related activities on traffic safety. The current meta-analysis aims at estimating non-driving related activities’ effects on takeover behavior based on theory and empirical findings on task switching and modality shifting. Results indicate that takeover time increases after non-driving related activities that (1) physically require the user to free his/her hands from the respective activity before takeover, (2) obstruct concurrent visual perception of the driving environment, (3) are dissimilar to the driving task in terms of required cognitive processing modules.

Using Task Switching to Explain Effects of Non-Driving Related Activities on Takeover and Manual Driving Behavior Following Level 3 Automated Driving

“…This study may provide first experimental support for a task switching approach to explain effects of non-driving related tasks on takeover behavior and following manual driving behavior. A metaanalysis has found first indication that support a task switching perspective [12]. This experimental setup shall provide further insight into causal effects.…”

“…Držení předmětu v ruce a jeho následné odložení má za svůj důsledek delší čas potřebný k převzetí řízení (Wan a Wu, 2018;Zeeb et al, 2017;Zhang et al, 2019), což se např. projevuje v prodloužení reakčního času v podobě položení rukou na volant (Shi a Bengler, 2022;Wandtner et al, 2018). Je zde i otázka vlivu obsluhy integrovaných elektronických zařízení (tzn.…”
