Driver Alcohol Detection System for Automotive Safety
The Driver Alcohol Detection System for Safety (DADSS) is a research program to advance the state of alcohol detection technology in vehicles. The research program began in 2008 with the goal of assessing the effectiveness and feasibility of alcohol-detection technologies. The program is now in Phase II, with additional research and testing of touch-based and breath-based sensors to improve accuracy and precision performance. The prototypes will then be installed in a research vehicle. This phase is expected to be completed early 2016. The technology will eventually detect a driver's blood alcohol concentration (BAC) in less than one second, and if it exceeds the legal limit of 0.08 percent the vehicle will not move. Two sensor technologies are being explored, a breath-based system and a touch-based system.
