Effect of route familiarity on attentional resource allocation during real-world road driving.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Previous studies indicate that route familiarity can adversely affect drivers' attentional states. However, few studies have examined how route familiarity affects attentional resource allocation using physiological measures. We investigated the effect of route familiarity on attentional resource allocation by measuring physiological indices during real-world road driving. Participants (n = 10) drove a vehicle on public roads on the same route over six days. We analyzed the eye-fixation-related brain potentials (EFRPs), auditory-evoked potentials (AEPs), and eye-blink duration from the electroencephalographic (EEG) and electrooculographic (EOG) signals as indices of attentional resource allocation. The results indicated that the P2 amplitude of the AEPs elicited by task-irrelevant auditory probes significantly increased on Days 3-4 and Days 5-6 compared to Days 1-2, suggesting that attentional resources allocated to cognitive processing decreased as route familiarity increased. The P1 amplitude of the EFRPs decreased across days, with a significant reduction from Days 1-2 to Days 3-4, suggesting that attentional resources allocated to visual processing also decreased as route familiarity increased. This study supports previous findings that route familiarity affects drivers' attentional states, providing new objective physiological evidence. We also discussed the differences in drivers' inattention caused by route familiarity compared to the driving duration.
