taxiway
Let an agent explain what taxiways are and how they are designed, marked and used, relay standards from ICAO and national authorities, and distinguish taxiways from runways and aprons.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain what taxiways are and how they are designed, marked and used, relay standards from ICAO and national authorities, and distinguish taxiways from runways and aprons.
A paved path at an airport connecting runways with aprons, hangars, terminals and other facilities, along which aircraft move under their own power; taxiways are marked with yellow centrelines and edge lines, lit with blue edge and green centreline lights, named by letters, and designed by width, bearing strength and separation according to aircraft codes.
What it is for: Moving aircraft between runways and other airport areas.
It can be explain function and design; explain markings, lighting and signs; relay standards; distinguish from runways and aprons.
Distinguishing features

Yellow markings
Lettered designations
Designed to aircraft codes
What it looks like
A paved strip with a yellow centreline, blue edge lights at night, and lettered signs at intersections.
Physical character
width: about 7.5-25 m - by aircraft code letter
edge light colour: blue colour - centreline green
How it is recognised
Yellow centreline and blue edge lights
Connects runways and aprons
Runways have white markings and are for take-off and landing
