Distracted drivers are involved in approximately 4 million vehicle accidents each year in the U.S. (Dingus et al. 2016). These crashes result in many lives lost and billions of dollars in damages. This widespread issue has resulted in the adoption of regulations in the European Union that will require all new vehicles produced by mid-2022 to be equipped with driver monitoring systems (DMS; Gibbs, 2019). Although new vehicles would be required to incorporate driver monitoring, the optimal approach for determining/identifying inattention is still up for debate. This project leverages previous research, naturalistic databases, and input from recent literature to develop robust algorithms for assessing when drivers are inattentive to the driving task, while also investigating limitations of different approaches and sources of information. Effectively detecting distraction and inattention can enable automakers to develop countermeasures against this behavior and thereby increase safety for all road users.
- This research found that algorithms used to determine driver attention should be designed with an understanding of their limitations and that glance location data alone cannot definitively determine a driver’s attention state. At a minimum, both glance location and speed should be used to assess driver attention.
- A variety of algorithms were designed to measure driver inattention, as well as ways to directly compare algorithm performances to find specific events that create differences between methods.
- This project was presented at the 2022 LifeSavers Conference in Chicago in the workshop, “What Are You Looking At? The Importance of Driver Monitoring.” The student presenting this project was also recognized as a 2022 LifeSavers Traffic Safety Scholar.
