Taxiway

A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities.

They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass.

[1][2] Busy airports typically construct high-speed or rapid-exit taxiways to allow aircraft to leave the runway at higher speeds.

This allows the aircraft to vacate the runway quicker, permitting another to land or take off in a shorter interval of time.

Vehicles and aircraft are required to stop at these signs until the control tower gives clearance to proceed.

The signs can often be combined, in this case a direction sign, a location sign, and a runway sign.
