Which mode places all available elevators at the building entry floor in anticipation of many upward traveling passengers?

• A. Up peak mode
• B. Down peak mode
• C. Independent service mode
• D. Inspect mode

Answer: (A)

Up-peak operation is used when many passengers want to go upward from the lobby. The control system concentrates all available elevators at the building entry floor so upward trips can be served quickly, reducing waiting time for people starting their journey from the lobby. After handling the lobby demand, the cars can be distributed to upper floors as needed. This contrasts with down-peak, which focuses on moving many passengers downward to the lobby; independent service assigns cars to specific zones or floors with limited coordination; and inspect mode is for maintenance and testing rather than regular passenger service.
