Summary
This review article addresses the methodological inconsistencies in studies investigating the effects of cell phone use on driving performance using driving simulators. The authors argue that the diverse characteristics of simulator designs and scenarios across previous research have led to varying cognitive workloads, making it difficult to compare results or accurately estimate the impact of mobile phone conversations on driver safety. The study aims to develop a checklist for controlling cognitive specifications in such studies by analyzing the methodological characteristics of prior research. The authors conducted a systematic review of articles published between 2002 and 2017, searching databases including Springer, Elsevier, PubMed, and Google Scholar. They selected 14 studies that simultaneously involved mobile phone conversation, driving simulator use, and the assessment of driving behavior or cognitive workload. The review evaluated these studies based on factors affecting cognitive function, focusing on simulator specifications and scenario design variables. The analysis revealed a significant lack of convergence in how studies reported simulator and scenario characteristics. Key variables such as vehicle speed, road type, number of lanes, traffic load, path length, and weather conditions were reported inconsistently, with many studies omitting critical details. For instance, only four of the 14 studies reported traffic load specifications. The authors identified seven major domains influencing cognitive workload: driving simulator sophistication, visual attention and processing limits, road characteristics (including environment, width, and signs), weather conditions, road complexity, speed, and environmental conditions like temperature. The review highlights that increasing visual components or scenario complexity can either overestimate or underestimate the cognitive workload imposed by phone use, depending on the baseline difficulty of the driving task. The significance of this work lies in its provision of a structured checklist to standardize the reporting of cognitive characteristics in dual-task driving studies. The authors conclude that the lack of standardized scenario design leads to biased estimations of mobile phone effects on driving performance. By accounting for variables such as visual stimuli, road geometry, and environmental factors, future research can more accurately assess cognitive workload and improve the comparability and validity of traffic safety studies. This checklist serves as a tool for researchers to ensure that simulator environments adequately control for cognitive load, thereby enhancing the reliability of findings regarding distracted driving.
