Tram in/on road HOV lane

[odrzutowiec]

Hi.
Somewhere on this forum I found a marvellous idea. Instead of nonexisting tram in AVE 6, tram in road plus two one-way roads on each side can imitate the same system.
And I think it would be great to restrict the traffic on the tram on road lane only for buses (and obviously trams), so that we could create something like this in Amsterdam:

Honestly, I have no idea how to do this, that's why I kindly ask if somebody could make such pieces? There are some HOV lanes lots for roads so I guess it's possible to make such thing..Correct me if I'm wrong.
What do You think?

My thought in theory, a copy of the HOV lane lot would need to be made, but the traffic pathways from the existing Tram in Road network would have to be remapped to that new copy. It's just I can't touch that though. I don't exactly have the know-how.
