In the image below, you can see a visual of the new runway (in red) which will be constructed at the Prague airport.

I understand the need of multiple crossings, but one thing I don’t realize is the side pathway you can see on the left side, where when departuring from the airport, you can turn right, away from the runway. I am talking about the green circled part specifically. What purpose does it have?
In: Engineering
I think what you’re looking at are taxiways, these are roads that planes use to get towards a specific point on a runway (to take off) or leave the runway, to get back to the terminal after a landing.
In short, you only want to use runways for 2 things: landing and taking off. If a plane is not actively doing any of that, it needs to get outta there.
This is both for safety reasons: Another plane won’t land on top of you while you’re slowly moving on the ground.
And economical: As long as a plane is on that runway, another plane can’t use it, that’s money that you’re burning!
And taxiing (a plane moving on the ground) is slow, so you don’t want to keep that runway occupied for 20 minutes while you slowly putz to the start of the runway.
There are multiple places to get on and off the runway towards the taxilanes to make this process quick, because you don’t want to be on one, you’d rather be safely next to one.
