traffic Peds movement on path nodes

[Thomas_Nightfire]

Now I'm just try to understand how NPC HLC Traffic and 'traffic' (default MTA resource) is working, i.e. how the peds choose where to move and where to stop, etc.
I know: peds randonly spawn around player on closest nodes and moves to another nodes. Nodes have flags (roadblock, emergency, highway, etc.). Each node have a links to another nodes. But for what a node need a neighbors and links and how it using, I don't know.

Can't understand how they choose the right node from others. Please, explain how this system works. I suppose this algorithm has been taken from singleplayer, right?
I've read an article at https://gta.fandom.com/wiki/Paths_(GTA_SA) trying to find out, but couldn't...

Take a look at this function:

This function allows you to calculate the shortest distance between a line and a point. If you did that for every line between the notes, you would be able to figure out which one is the closest to your ped or car.

For what? May be I just need to get the distance between two points? Ped pos and node pos?
And my question not about it. It's about traffic system

I only gave you the concept of how traffic resource is doing that. You think you wouldn't find an enchanted version of that same code in the traffic resource? I am pretty sure there is, which is where  you could start your search + understanding the code.
