Firstly, thank you for the unit test and against this very new and alien concept to Infrastructure.
The file is Syntactically correct which is highlighted by the passing checks, but semantically there are a few issues around the organisation of the spatial hierarchy. we are trying to make sure the unit tests are simple representatives both in syntax and modelling practices so the advised changes are as follows:
- ROADSEGMENT is logically not associated to a LATERAL IfcFacilityPart and more suitable value would be TRAFFICLANE;, which would make this model a 2 lane road.
- longitudinal segments can be decomposed into lateral parts or vice versa but logically usually don't exist as a siblings in the hierarchy.
- the conceptual organisation of the model is a bit perculiar as it is the road and railway both pass over the bridge (inferring they are side by side) then they intersect. would it be more understandable and to highlight the possible elements better by having one PassUnder then intersect further along??
once these are discussed and resolved we can merge this useful unit test!

As per the developing Documentation around IfcRelInterferesElements PassesOver and PassesUnder is directional in nature so it should be as below.
- PassesOver: the RelatingElement is passing over the RelatedElement (e.g a bridge passing over a water canal)
- PassesUnder: the RelatingElement is passing under the RelatedElement (e.g a Pipe passing under a road)
therefore your relationships are currently backwards (e.g. Bridge passesOver Road... :P)

Okkk! Let's see if I got this right!
Unit test
Test the interaction / interference with different domains spatial structures.
