Railway travel is an eco-friendly means of transportation, and passengers are spending increasing amounts time on trains while engaging in various activities. As a major factor affecting railway passengers’ comfort, we investigated the effects lighting. Korean train cars required to have two rows light-emitting diode lights with minimum illuminance 500 lx, so examined changes cerebral blood flow under conditions around this threshold value. We used functional near-infrared spectroscopy measure prefrontal cortex activation 29 college students values 300, 500, 800 lx color-temperature 2700 K (bulb color), 4000 (white 5500 (blue color). Mean brain activity were compared using analysis variance. Of 48 channels, significant interaction between color responses observed for channel 38, as well right dorsolateral among different regions Brodmann area (p < 0.05). Oxygenated hemoglobin concentrations had consistently negative all treatment combinations, individual analyses based single-sample Student’s t-tests showed degrees channels areas. Meanwhile, comparison absolute indicated that level was more comfortable than levels 300 white bulb blue color. These results provide scientific basis design improve passenger comfort satisfaction, which anticipated enhance quality services.

ABSTRACT Background Brain imaging technologies can measure fluid intelligence (gF) levels more directly, objectively, and dynamically, compared to traditional questionnaire scales. To clarify the temporal mechanisms of graph theory in measuring gF, this study investigated relationship between theoretical indicators dorsolateral prefrontal cortex (DLPFC) gF under various time windows. Methods Using 30‐min resting‐state fNIRS (rs‐fNIRS) data Raven's Advanced Progressive Matrices from 116 healthy participants, individual DLPFC brain signals was analyzed using average degree (AD) global efficiency (Eglob). Results AD Eglob were significantly negatively correlated with RAPM score. Considering effectiveness measurement, a 2‐min collection might suffice, while for Eglob, than 15‐min effective. Conclusion These findings help demonstrate rs‐fNIRS providing practical basis portable objective assessment .
