Passenger comfort visualized assessment in high-speed railway tunnels using functional near-infrared spectroscopy (fNIRS) brain imaging technology: A full-scale test study

Key Points

• Passenger comfort visualization indicates varying levels of satisfaction within high-speed railway tunnels, and improvement recommendations arise from findings.
• The most significant metric shows that fNIRS technology effectively captures passenger brain activity linked to comfort in real-time.
• Observational analysis using functional near-infrared spectroscopy highlights brain responses in varying tunnel conditions across full-scale tests.
• The study suggests that enhancements in tunnel environments could significantly benefit the passenger experience while using brain imaging technology.
