In what way does reflective material improve safety for travelers using Blue Stripe signage?

Reflective material significantly enhances color visibility in low light conditions, which is crucial for safety in busy environments like airports. When travelers move through areas that may be dimly lit or during nighttime, reflective materials help ensure that signage is clearly visible. This visibility is particularly important for directing travelers to key locations, ensuring they can navigate safely and confidently without confusion or accidents.

While other options may seem relevant in different contexts—such as showing staff shift patterns, providing flight updates, or creating a relaxing atmosphere—none directly pertain to the immediate, practical safety benefits of signage visibility. Clear and visible signage allows travelers to stay informed and aware of their surroundings, contributing to a safer travel experience.
