Public concern about impaired driving in general and drug-impaired driving in particular has increased in recent years with distracted driving and being drowsy or sleep deprived further adding increased risk to an already complex task. As a result, the need for the development of early warning systems for driver monitoring is critical for preventing motor vehicle collisions and human fatalities.
ACS is pleased to announce positive results of recent research towards the development of non-intrusive Artificial Intelligence (AI) technology to screen for cannabis impairment.
Based on research conducted in collaboration with the Centre for Addiction and Mental Health (CAMH) ACS has designed and developed a Cannabis Screening System using AI models and eye-tracking information from dozens of eye-tracking features for non-intrusive cannabis influence assessment in drivers.
“The overall results of this research are encouraging and show that several eye tracking features highly correlate with one or both target measurements of blood THC level and Standard Deviation of Lateral Position (SDLP) measurements,” says Felix J.E. Comeau, President & CEO of ACS. “These results reveal the potential of eye tracking information to be used as a non-intrusive marker of THC presence and/or impairment for driver monitoring.”
The research results also show that both THC presence and instances of impaired driving can be detected with high accuracy (95% for THC and 81% for impairment detection) using deep learning methodologies.
With approximately 24% of drivers reporting driving within two hours of cannabis consumption and with increased accessibility of cannabis through legalization, a reliable Cannabis Screening System will provide an easy-to-use, non-intrusive screening solution which can be employed by law enforcement officers at the roadside for fast and cost-effective assessment of driver impairment. Additionally, such systems can also be used for in-vehicle driver monitoring and continuous real-time evaluation of driver vigilance to reduce impaired-driving incidents in the transport-industry, public transit and passenger vehicles.
