What is a "pavement marking" on the airside?

A pavement marking on the airside is defined as lines or symbols painted on runways and taxiways that serve the crucial purpose of guiding vehicle operators. These markings are essential for ensuring safe and efficient movement of vehicles and aircraft on the airside. They provide clear visual instructions regarding various operational aspects, such as taxi routes, hold short lines, and parking areas, making it easier for vehicle operators to navigate complex airside environments.

In contrast, while decorative patterns may enhance aesthetics, they do not have a functional role in guiding operators. Safety barriers for vehicle parking and digital signage serve different purposes related to safety and information dissemination, but they do not fall under the category of pavement markings. This makes the choice that focuses on painted lines or symbols the best definition of pavement markings in the airside context.
