In December 2007, the ECB decided in conjunction with the Federal Reserve System under a programme called Term auction facility to improve dollar liquidity in the eurozone and to stabilise the money market.

Question: Some skyscraper buildings and other types of installation feature a destination operating panel where a passenger registers their floor calls before entering the car. The system lets them know which car to wait for, instead of everyone boarding the next car. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced, passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period the benefit of destination control will be limited as passengers have a common destination.
Is there an answer to this question: What is another benefit of a "destination operating panel"?

Answer: the computer distributes adjacent stops to different cars in the bank
