Summary
This research addresses the safety challenges at short-storage highway-rail grade crossings (HRGCs), where limited space between tracks and nearby intersections restricts vehicle stopping areas. Despite rail safety improvements since the 1990s, incident trends have flattened, and short-storage crossings remain cognitively demanding for drivers. The study aimed to systematically analyze how crossing type affects driver decision-making, attention management, and incident outcomes, filling a gap in existing literature that had not previously compared short-storage and non-short-storage crossings. The researchers conducted two studies. Study 1 analyzed real-world data from the Federal Railroad Administration (FRA) safety database for incidents occurring between 2017 and 2019 across six U.S. states. Using Google Earth imagery, researchers identified 996 incidents, categorizing them as short-storage (under 200 feet of space) or non-short-storage. Study 2 was a controlled laboratory experiment involving 48 college-aged drivers who annotated safety concerns in images of both crossing types, with a subset undergoing passive eye-tracking to measure gaze duration and fixation patterns. Study 1 found that 20.3% of incidents occurred at short-storage crossings. These incidents disproportionately affected older drivers (mean age 46.5 vs. 42.9) and resulted in different pre-crash behaviors; motorists at short-storage crossings were more likely to be stopped on the tracks (42% vs. 28%) rather than moving across them. Additionally, short-storage incidents resulted in train strikes more frequently (91.3% vs. 78.8%) than non-short-storage incidents, though injury severity did not differ between types. Study 2 revealed that participants identified more safety concerns and rated them as more severe for short-storage crossings. Content analysis showed a shift in attention: drivers focused more on rail-related dynamic cues (signals, trains) at short-storage crossings, whereas they focused primarily on traffic concerns at non-short-storage crossings. Eye-tracking data indicated an interaction between driving experience and crossing type, with rural drivers exhibiting longer gaze durations on short-storage images. The findings demonstrate that short-storage HRGCs present distinct cognitive and behavioral challenges compared to standard crossings. The higher incidence of older drivers and the shift in attention toward rail-specific hazards suggest these locations require targeted safety interventions. The results provide a foundation for developing hazard perception training and countermeasures tailored to the unique demands of short-storage environments, potentially reducing the frequency of train strikes and improving overall rail-highway safety.
Key finding
Drivers reported significantly more and more severe safety concerns at short-storage crossings, and real-world data showed these locations had higher rates of train strikes and incidents involving older drivers.
