Summary

To analyse driving behavior of individuals under the influence of alcohol using a validated research driving simulator. Based on the driving variables provided by the simulator the investigators aim at establishing algorithms capable of discriminating sober and drunk driving patterns using machine learning neural networks (deep machine learning classifiers).

Conditions

  • Transportation Accidents
  • Drunk Driving
  • Alcohol Drinking
  • Impaired Driving

OTHER

Driving under the influence of alcohol with a driving simulator

Participants will drive in three different states (sober, drunk above and below the legal limit) on designated circuits using a driving simulator. After the initial sober driving session, participants are administered pre-mixed alcoholic beverages (e.g., vodka orange). Participants are expected to achieve a target BrAC of 0.35 mg/l (legal limit in Switzerland is 0.25 mg/l BrAC) before the second driving session starts. Finally, the third driving session starts when the participants' BrAC drops to 0.15 mg/l. Heart rate, skin conductance, accelerometer, eye movement, radar, facial expression, and speech will be recorded by a smart-watch, an eye-tracker, microphones and an onboard camera, respectively. Participants will be blinded to their alcohol levels during the study. They will have to rate their symptoms and their performance via questionnaires before and after each driving session. Further, capillary blood and oral fluid samples will be collected.
