This idea's advantage is you don't have to built a railway, I think their design is using regular bus tires, I don't see a rail on the drawing anyway.
They also suggest either rails or tires that follow a predefined track. It would likely require resurfacing the road at a minimum, possibly a lot more.
If it can't accommodate trucks then that lane would be limited to auto traffic so it wouldn't help logistics companies that much.
It looks like it would be the inner two lanes of a freeway, and quite often trucks are meant to stay in the outer slow lanes anyway.
They suggest it has to fit under over passes, but over traffic, so making it as high as a truck is not optional. I do foresee accidents where a vehicle too high to fit under crashes into it (as frequently happens with low bridges). But since they will typically be going in the same direction, that might reduce the impact.
One concern is that it might be very confusing for a driver going though it. Imagine driving through a short tunnel that is moving at 60km/h. I guess it would be similar to going between two rows of buses.
I just had a flash, the same idea could be made to carry cargo also! Doesn't have to carry just passengers.
The limited routes would make it equivalent to rail transport.
