Oke....I understand your concern... ... but construction is not correct anyway.
In fact... The tagging is right. 
The highway=busway implies 
    access=no
    bus=designated
    emergency=yes
The problem is the routingapp infact.

No regular traffic will route over this busway.

So better inform the develloper of the routingapp.

You may ask some advice at the OSM forum.

English is no problem.
