A simulation model of a standard security checkpoint of the Transportation Security Administration (TSA) is compared to two other simulation models, which represent two different alternatives designed to alleviate the congestion of passengers at the exit roller area of a generic representation of a security checkpoint. Both alternatives consist of separately processing passengers who travel for business from those who travel for leisure. However, for the second alternative, a non-stop circulating conveyor is modeled in place of the exit roller of the checkpoint line. The results show that the non-stop circulating conveyor decreases the system time for both business and leisure passengers, and it significantly improves the hourly throughput of passengers.
