Sample Projects


Under the Driver Alcohol Detection System for Safety (DADSS) Program, KEA leads all in-clinic and field-based testing activities with human subjects. These studies involve precisely dosing eligible participants with alcohol to test and refine novel-alcohol sensing technologies that are being designed to be implemented in consumer vehicles in the United States.

This testing occurs both in a clinic environment where researchers are able to collect blood and other biological samples as well as in the field in research based vehicles.

Habituation to Auditory Alerts in a Locomotive Cab

As part of a Federal Railroad Administration (FRA)-funded human factors research, KEA Technologies Inc. utilized the Cab Technology Integration Lab (CTIL) at the Volpe Center located in Cambridge, MA to investigate the effects of various auditory alerts on experienced locomotive engineers. Researchers were primarily interested in whether habituation to in-cab audio alerts may occur as observed in other sectors.

The simulator track was programmed to have areas of both high and low workload and lasted for a prolonged period. Throughout the duration of the study, a few novel tones were introduced randomly, and researchers instructed operators to acknowledge this tone by pressing a button in the simulator. The goal of this study was to do a preliminary investigation on an aspect of locomotive operations that has not been fully researched with regard to performance, workload, and alerts.
