I have been reading about OSM Road from accepted answers here like,
how-to-split-osm-roads-into-individual-segments-at-intersections
finding-all-segments-that-makeup-a-road-in-osm
and my question,
does-osm-road-segments-contain-intersections
The answers fell short in explaining whether the segments in an OSM Road belong to a single road or grouped together from multiple roads. Since OSM Roads have intersections(answered in third link above), does it mean OSM Roads actually contain roads where travelling in multiple directions is possible.
To put it clearly,
- Is the road uni directional - one way or two way
- Does the OSM roads has structures like T-Joints (where the road has information(GPS points) on roads connected to an intersection.). Usually it is not possible for us to travel in both directions at the same time. So having OSM ID for GPS points in different road segments where you cannot travel, does not make sense to me.
- Where can I find the reference or documentation for these latent information for OSM.
Note: If the question seems too abstract, let me explain, I am trying to understand the OSM, since I'm using it for my research.
