What is one of the two overlying principles of passenger way finding?

The principle of considering the entire wayfinding chain is critical because it emphasizes the importance of creating a comprehensive navigation experience for passengers. This approach acknowledges that travelers interact with various elements of wayfinding, including signage, maps, mobile apps, and even staff interactions, throughout their journey. By focusing on the entire chain, airports and transport facilities can ensure that each component works together cohesively, guiding passengers seamlessly from one point to another.

This principle fosters a holistic view of how information is communicated, ensuring consistency and clarity at every stage of the passenger's experience. It also allows for the identification of potential gaps or overlaps in communication, which can lead to confusion for travelers. Therefore, addressing the entire wayfinding chain is essential to improving passenger flow and overall satisfaction.
