comment How do algorithms load pieces of maps?
Thanks, but I'm not working with tile images. Am working exclusively with the nodes of a road network. All my algorithm needs to know is which road-nodes are present in a certain region which I wish to load. My question is how these points will be stored (In C++) and recognized as squares or sections of the map. I'm sure there would be an efficient way to do it...

comment How do algorithms load pieces of maps?
I'm not working with tile images. The algorithm I'm writing deals purely with lat-long points. The 'pieces' of maps I'm loading are only sections containing road-networks and/or railroad networks (maybe vegetation boundary vectors much later). The road network within these sections will be processed by my algorithm. I'm sorry if I used the word 'tile' inappropriately. Maybe 'map-section-for-roads' would be more appropriate.

comment What's an efficient way of detecting road junctions on a map?
@Kirk: I'm a bit shocked at the situations you've mentioned. I'm new to GIS, and didn't even know that such possibilities existed. 1.Self intersection requires multiple segments. Unless it's a flyover, I would consider those intersections as junctions. 2. I'm not even able to visualize what degenerate geometry is, so I don't know what to answer. 3.Coinciding lines should be treated as two separate roads because that's how I assume they would be in real life too.
