Summary
This 2016 literature review, sponsored by the National Highway Traffic Safety Administration (NHTSA), addresses the impact of electronic device use on pedestrian safety. The research was motivated by rising rates of distraction-related crashes and injuries, with NHTSA reporting over 3,000 fatalities and 431,000 injuries in distraction-affected crashes in 2014. While driver distraction is well-studied, the specific risks associated with pedestrian distraction and the interaction between distracted pedestrians and drivers remain poorly quantified. The review aims to synthesize existing knowledge to inform future naturalistic observation and crash data analysis projects. The authors conducted an extensive search of databases including Psych Abstracts, PubMed, and TRIS, reviewing 118 documents and selecting 80 for final inclusion. The review is structured into three primary sections: pedestrian distraction, driver distraction, and pedestrian-vehicle interactions. Within each section, studies are categorized by methodology, including naturalistic observations, simulator-based studies, laboratory experiments, and crash database analyses. The review also incorporates traffic conflict research to evaluate safety-critical events at intersections. The findings indicate that pedestrian distraction is a confirmed issue affecting walking behavior, reaction times, and safety-related actions, such as looking for traffic or staying within crosswalks. Naturalistic studies show that cell phone users exhibit more unsafe behaviors, take longer to cross, and are more likely to weave or stop unexpectedly compared to non-distracted pedestrians. However, the review notes a significant gap in the literature: there are no studies establishing a direct link between these behavioral changes and actual pedestrian crash risk. In contrast, driver distraction is extensively documented, with quantified risks associated with specific distractors like texting. Regarding pedestrian-vehicle interactions, the review highlights that few studies examine simultaneous distraction, and existing data on joint distraction effects are limited. The significance of this review lies in its identification of critical research gaps. It concludes that while pedestrian distraction alters behavior, the extent to which this increases crash risk is not well understood. The authors emphasize the need for naturalistic observations to quantify the effects of electronic device use on both pedestrians and drivers during interactions. The review also underscores the value of integrating engineering-based traffic conflict analysis with psychological studies to better assess safety at intersections. This work serves as a foundation for subsequent phases of the NHTSA project, which aim to collect field data and analyze crash reports to more accurately quantify distraction-related risks.
Key finding
The review concludes that while pedestrian distraction affects safety behaviors, there are no studies showing a direct link between the behavioral effects of distraction and pedestrian crash risk.
