Summary

This document is an issue of *Public Roads*, a bimonthly publication by the Federal Highway Administration (FHWA), featuring several articles on transportation research and policy. The primary research article, "When Distracted Road Users Cross Paths," addresses the safety implications of inattentional blindness among drivers and pedestrians. Motivated by rising crash statistics involving distraction, the study investigates how divided attention affects yielding behaviors at midblock crosswalks. Researchers from the University of North Carolina at Charlotte conducted observational field studies at seven campus crosswalks. They recorded interactions between 325 drivers and pedestrians, categorizing distractions into talking on cell phones, texting, or other activities. The study specifically analyzed yielding patterns and conflict occurrences, defined as abrupt changes in speed or path to avoid collision. The findings reveal that approximately 18% of drivers and 29% of pedestrians were distracted. Distracted drivers were 15 times less likely to yield to pedestrians than attentive drivers (5% vs. 77%) and four times more likely to be involved in conflicts. Conversely, distracted pedestrians exhibited aggressive crossing behaviors, such as failing to make eye contact or darting into traffic. This behavior compelled drivers to yield at higher rates (80% for distracted pedestrians vs. 57% for attentive ones), suggesting that drivers compensate for pedestrian inattention by stopping more frequently. The study concludes that high levels of distraction among either group increase conflict potential and crash risk. The article recommends infrastructure countermeasures to mitigate these risks, such as high-visibility crosswalk markings, pedestrian hybrid beacons, and median refuge islands, which help distracted users process critical information. Other articles in the issue discuss a new decision-making tool for Accelerated Bridge Construction (ABC) to reduce congestion and improve safety, the development of sustainable highway evaluation tools, and the application of Crash Modification Factors (CMFs) for safety engineering. The publication also highlights FHWA’s Cooperative Vehicle-Highway testbed for wireless vehicle-infrastructure technologies and provides an overview of the *Highway Statistics* data resource.

Key finding

Distracted drivers yielded to pedestrians at a rate of 5 percent compared to 77 percent for attentive drivers, and were involved in pedestrian-vehicle conflicts at a rate of 51 percent compared to 13 percent for attentive drivers.
