SBIR Phase II: Greenlight Readiness Assessment Technology
The project goal is to develop Greenlight, a readiness assessment technology designed to objectively measure drivers’ readiness before operating a CMV. This is a Small Business Innovation Research (SBIR) Program project currently in Phase II of the SBIR Program. The objective of a Phase II project is to continue the R/R&D effort from a completed Phase I project.
Fatigue represents a significant causative factor in vehicle crashes in the U.S. Driver fatigue can impair vigilance, working memory, and higher order cognitive and physical processes. Commercial motor vehicle (CMV) drivers experience factors that can lead to fatigue including long hours, long distances, night driving, exposure to varying weather and road conditions, and underlying health-related issues such as sleep apnea. This highlights the need for an objective, quantifiable measure to assess a driver’s readiness before operating a CMV.
Greenlight leverages wrist-worn sensor information to capture quantitative sleep and stress information from onboard pulse photoplethysmography and accelerometry sensors. Greenlight then provides a high-accuracy quantitative analysis of current and future readiness by leveraging artificial intelligence and machine learning models. This SBIR Phase II project includes full development of the Greenlight system, testing in a randomized controlled trial, and commercialization of the Greenlight prototype.
