What does it mean to shuttle?

The term "shuttle" specifically refers to the action of going back and forth between two points. This concept is often used in various contexts such as transportation services, where a shuttle bus might carry passengers repeatedly between a location and a destination. The key aspect of shuttling is the repetitive and alternating nature of the movement, distinguishing it from simply traveling or relocating, which do not inherently involve a back-and-forth motion. Thus, understanding "shuttle" in this operational context highlights how it is uniquely associated with continuous or cyclical transport rather than just traveling in a straight line or relocating from one place to another.
