Investigating the Effects of Alcohol Consumption on Manual and Automated Driving: A Systematic Review
Summary Information
Previous research has found direct links between drunk driving and car-related injuries, disabilities, and deaths. While Fully Automated Vehicles (AVs) have the potential to reduce road accidents with driver support systems, full automation without human intervention is still in development. Understanding the effects of alcohol on driving in both manual and automated scenarios is crucial for insights into the AV takeover process. This study reviewed 53 journal articles from eight global databases, categorizing findings based on the human information processing model (perception, cognition, and action), applicable to the AV takeover model. Journal or conference articles published between 1980 and 2022 (written in English) were included were included in the study.
- Consider ignition interlock devices in vehicles to detect alcohol consumption. The study mentioned a car invention called ignition interlock, which requires drivers to blow into the device and the car will unlock if the BAC level is less than the set limit.
- Establish consistent measurement standards and units for blood alcohol concentration (BAC). The study found that the definitions of low, moderate, and heavy alcohol levels and the measurement units varied across the reviewed articles, including different alcohol percentages or grams per deciliter.
- Provide a well-designed human-machine interface to assist drivers in better processing incoming information and quickly filtering out unusable information. The study suggested that this would be important following the cognition stage within the human information processing model (a framework that includes perception, cognition, and action stages to understand how humans perceive, process, store, and retrieve information).
- Establish a reliable automated driving support system to provide real-time feedback to the driver. The study explained how crucial such a system would be. For example, to inform the drivers using a tactile signal from the steering wheel or the driver’s seat.
