What is a taxiway used for?

A taxiway is specifically designed as a defined path that allows aircraft to taxi, or move, safely from one area of an airport to another, such as from the runway to a terminal or vice versa. This infrastructure is essential for the efficient management of air traffic on the ground, ensuring that aircraft can be directed to their designated places without interfering with other operations, including takeoffs and landings.

Taxiways are marked with appropriate signage and lighting to assist pilots in navigating the airport's layout, maintaining safety and organization on the airfield. They are distinct from runway areas and have specific design considerations to accommodate the movement of aircraft, differentiating them from other ground facilities such as storage areas or pedestrian pathways. Each taxiway is generally constructed to support the weight and dimensions of the aircraft that will use it.

Options that mention emergency landings, pedestrian pathways, or storage areas do not accurately describe the primary purpose and function of taxiways within the airport environment.
