Summary

This 1985 report by the Transportation Systems Center, sponsored by the National Highway Traffic Safety Administration (NHTSA), assesses the feasibility of developing in-vehicle systems to monitor driver attention and reduce accidents caused by alertness degradation. The research was motivated by the identification of driver inattention as a major contributing factor in traffic accidents, with estimates suggesting it plays a role in up to 90 percent of collisions. The study aimed to determine if techniques could be developed to detect reduced alertness in real-time and alert drivers or automatically intervene to prevent crashes. The methodology involved a comprehensive review of the state-of-the-art research on driver attentional processes, an analysis of the 1982 National Accident Sampling System (NASS) data, and an investigation of existing technologies for sensing driver alertness. The NASS data was selected as the first dataset to record detailed information on driver roles in accidents. The analysis focused on collisions where vehicles were in motion, categorizing drivers by their avoidance maneuvers, drowsiness, intoxication, and inattention. Additionally, the report reviewed physiological and behavioral indicators of inattention, such as EEG patterns, eyelid droop, and steering wheel motion, alongside a survey of automotive electronics available for integrating monitoring systems. The analysis of the 1982 NASS data revealed that 38 percent of drivers involved in collisions took no avoidance action prior to impact, suggesting significant attentional lapses. Specifically, among drivers judged to be inattentive, 31 percent of striking vehicles took no action. For drowsy drivers, 59 percent of striking vehicles failed to attempt avoidance. The data also indicated that drivers over 55 years old were less likely to make avoidance responses than younger drivers, and accidents attributable to drowsiness were more frequent during early morning hours. The review of monitoring technologies identified various devices, ranging from simple head-droop alarms to complex microprocessor-based systems monitoring steering patterns, noting that combinations of driver indicators and environmental data could improve detection accuracy. The study concluded that attentional lapses are a major cause of highway accidents and that experimental investigation into multivariate monitoring techniques holds a high probability of identifying useful methods. The authors recommended a two-phase approach for further development: a simulation phase to evaluate detection algorithms and a field test phase to assess practical performance. The report emphasized that while physiological measures like EEG are informative, they are often secondary indicators, and practical systems must reliably discriminate between changes in response due to alertness versus driving conditions. The findings support the development of demonstration programs to refine these technologies for widespread automotive use.

Key finding

Analysis of 1982 NASS data showed that 38 percent of drivers involved in moving collisions took no avoidance action prior to the crash, indicating that attentional lapses are a major factor in highway accident causation.
