Non-invasive method for detecting drug and alcohol impaired drivers: a study of alcohol and drug biomarkers and optical detection techniques

The purpose of this project is to map substances that constitute a possible threat to traffic safety, identify suitable detection markers as a proof of administration of these substances, and study possible non-invasive techniques to detect these markers. The objective is to evaluate and develop a non-invasive detection device. The project has been carried out by performing an extensive literature study and a verification experiment. From the literature review, a number of substances affecting driving performance could be identified, and a metabolic study was performed for each drug to map suitable biomarkers. Furthermore, two potential techniques for non-invasive detection, near-infrared Raman spectroscopy and near-infrared spectroscopy, were found and evaluated. The experiment was conducted using near-infrared Raman spectroscopy, with the aim of investigating the sensitivity and linearity of the method for ethanol detection. Based on the theoretical evaluation, both near-infrared Raman spectroscopy and near-infrared spectroscopy are expected to have potential for non-invasive detection of ethanol. The experiment further proved the theoretical conclusions made for near-infrared Raman spectroscopy. However, neither of the techniques is thought to have potential for drug detection. Although it appears that non-invasive ethanol detection is possible further experiments are needed in order to determine which technique to be preferred.
