I have ORS running on my server, and I’m curious as to how ORS handles the maximum_snapping_radius parameter.

Does it look for the closest road to the point within the radius or does it just grab any old road in the radius.

It finds a point on the closest edge to the location specified. The maximum_snapping_radius property tells the system how far it can look away from the location before it returns a “Point not found” error.
