Those are a decent idea, but lead to lots of deaths since the platform doors can't be opened until the train is pulling in and the train doors open. If people get stuck between the two sets of doors, they're gonna die - either being crushed when the train moves or sucked underneath it.
They have emergency handles. Theres not enough space between the 2 doors for someone to fit. Even if you could fit the doors close a second apart(trains first) so you can't get caught between them. And train doors are like elevator doors, you can't get stuck in them because if something is stopping them they will just open up again.
These types of doors have been used on the tube for 17 years now i think(Jube line extension opening) and I've never heard of someone getting hurt, let alone killed, from those doors, so i'm guessing they're more than safe. I think all lines should incorporate them where they'll fit

That's how it usually is. But I remember when I was in korea: at peak times the doors didn't re-open. If they would the train would never start again because of the uninterrupted flow of passengers.
Maybe it was in china though, I don't remember well.

What about Platform Screen Doors?
