When the Program began in 2008, DADSS focused on research and creation of proof-of-concept prototypes to determine which technological approaches were most promising for vehicle integration. After extensive research, it was determined that two technology options were most viable: a breath-based system and a touch-based system.
In 2013, ACTS and NHTSA extended their agreement, and the Program entered a new phase to reduce the size of the systems and ensure strict performance specifications are met relating to speed, accuracy, precision and reliability. As part of the ongoing research, the prototypes will be integrated in vehicles for a series of field tests, which will allow engineers to observe driver behavior in natural settings and thoroughly test the systems in real-world scenarios. Once completed, auto manufacturers will be able to offer the system as a safety option in new vehicles. It will take time for this pioneering technology to be available commercially, but developing a system that is seamless, accurate and reliable is the first step and a top priority.
