Finding Connected Intersections from Current Road Segment

[buraksenkus]

I want to find possible intersections can be reached from a given location (with bearing) but I couldn't figure out how can I do it. Here is the my goal in detail:

1. User provides a location (in lat-lon) and bearing (in degrees).
2. The nearest road segment is found by given values.
3. The possible intersections can be reached from the road segment are listed. Intersections can be reached in opposite direction are ignored.

The illustration can be seen from below figure.

Using nearest function is suitable for the second step but I don't know how to proceed for step 3. As far as I inspected, route function provides intersections on the suggested route but I don't have a destination location to use in route request.

Finding intersections in depth 2 or 3 is enough for me. I'm sorry if this is already asked previously but I couldn't find a relevant issue.
