taxiway

Not to mention that the frequency is probably used for many other types of communication than announcing the use of that specific taxiway.

Getting out of your seat on a taxiway is a bad idea.

It doesn't matter what the orientation of the taxiway is.

If you can't see when you're stopped straight on the taxiway centerline, you stop at an angle instead.

Which is a metric that assumes a certain length of runway infront of you, not a taxiway.

With airports, leaking a location for a major component of active perimeter and taxiway monitoring is a serious issue.

They tried to land in the SFO taxiway nearly missing several jets not too many years ago.

We had a plane catch fire on a taxiway and burn, and no electrical mayhem resulted.

One house even has its own tunnel under the taxiway to so that the owner can get to his house.

That controller lost situational awareness due to task saturation as a result of emergency aircraft on taxiway parallel to runway 13.

After touchdown, the plane drifted left and departed the runway, crossing a taxiway before coming to rest in a saltwater marsh.

Once the plane is stopped, it has to wait isolated at the taxiway because there are temperature plugs at the tires that may blow out, nobody can get close during that time.

"Some flights were on the taxiway and diverted back to the terminal after the problem was detected" Why?

So, there isn't much to discern about the signage other than "You are on taxiway X" vs "You are approaching taxiway Y [or runway Z" vs "Here is the hold line for purpose P", but there isn't any systematic way to know how to get to runway 18 without the airport diagram or directions from ATC.

You get directions from "Ground" (the ATC position in charge of the movement areas other than the runway): "<Aircraft>, Taxi [to] Runway XX via [taxiways] A, Q, M3, hold short [of] runway YY." You also have taxiway charts (paper or electronic).
