Here is one example of many:
Take the Six Flags White Water amusement park in Atlanta, which implemented a priority queue system in 2011.
Some guests simply queue up for their rides. Those who purchase green-and-gold wrist bands – fitted with radio frequency technology – are able to swim in the pool or eat snacks before being alerted to their turn.
Guests who pay an even higher fee – roughly double the price of admission – get the gold flash pass, cutting their waiting time in half.
The company says it has been a huge hit and is now installing the system in all of its American water parks.
The priority queuing system has also started to be extended to the public sphere. Many people who drive to Six Flags White Water take Interstate highway I-85.
In October 2011, Atlanta created a priority lane on the highway for drivers with a Peach Pass – the price of driving in the lane changes depending on how much traffic there is.
