Anglar, what do you mean Rome?
And what do you mean "for Broadway"? Do you mean like how each city might be treating how they bring back live theatre? (Frozen in Australia is at 75% capacity, for example.)
But to answer what I think is your question, no, I don't believe there's a site that's aggregating various theatres' standards for health/safety.
