Designed specifically for tunnel emergency scenarios, this emergency escape guidance traffic sign uses a dual-mode lighting system of active photoluminescence and passive reflection to provide reliable escape guidance even during tunnel fires and power outages. Targeted at tunnel management departments and urban underground project construction units, its core value lies in solving the problem of lost direction for drivers and passengers during tunnel emergencies, reducing casualties and property losses. The sign’s flame-retardant and smoke-resistant design ensures stable performance in high-temperature and smoky environments, meeting international tunnel safety standards.
