Simulating Random Agent Movements along Roads on Map

I need to simulate agent movements on map as follows:

Agent starts a known location and moves along a road. At each road intersection, the agent uniformly chooses one possible road and moves along that. The path chosen is to be traced with a poly-line.

I know how to choose a path uniformly and mark it with poly-lines once I have the data. But I am looking for how I can retrieve data like road intersection points and the roads leading from there on.

This question belongs on gis.stackexchange.com or similar SE sites, because it has no specific connection to OSM (you are just using OSM data).

The question belongs to this forum, as I want to find road intersection along a given road form osm data

Gormo is right, this has very little to do with OSM, the issue is a generic data issue and would be the same if your underlying geodata came from any other source. (Not that I am not interested in how useful OSM data might be for such an application.

Besides, how to detect intersections has already been answered in a different question.
