In bus route relations the ways don't get roles.<br>

In walking and cycling route relations we do use them. Those are bidirectional, whereas the bus and tram routes describe start to terminus for all variations.<br>

I'm unsure how you can suggest bus routes aren't bidirectional. They can go both ways along a way the same as walkers/cyclists.</blockquote><div><br></div><div>Bicycle and walking routes rarely loop back on themselves on otherwise linear routes.</div><div><br></div></div></div></div>
