NEW YORK—The breathtaking views from the observation deck atop One World Trade Center will become a magnet for millions of visitors when it opens in 2015. But there is much more in store for those who will visit the world’s third tallest building.

Plans have been unveiled for an hour-long observation deck experience at One World Observatory, which will start as soon as visitors queue up in the lobby. People will register by entering their names and locations on touch screens. The system will then display how many people from that location have visited the observation deck.
