Advantect OSB has worked great for our railroad passenger car floors, 15 years so far, and it is exposed on the underside, carpeted inside. The carpet lasts about 5-7 years, so when we change carpet it is a good time to see how the floor is doing and it holds up very well.
So from this experiance I would be good with it on a bus floor
