How are passenger walkways identified on the airside?

Passenger walkways on the airside are identified with white markings. These markings provide clear guidance to passengers for safe movement in busy areas, helping to enhance visibility and safety. The use of white markings is standard because it contrasts well with the typically darker surfaces of runways and taxiways, making it easier for passengers to follow designated paths, especially in low-visibility conditions. This is important in busy airport environments where safety and organization are paramount to prevent accidents and ensure smooth passenger flow.
