Which term refers to a panel that directs traffic in lobbies of elevators?

The term that accurately refers to a panel that directs traffic in the lobbies of elevators is the lobby controller. This panel plays a critical role in managing the flow of elevator traffic by allowing users to call an elevator to their desired floor. It communicates with the elevator control system to ensure efficient operation and reduce wait times. The lobby controller helps optimize the service provided by the elevators, guiding them to respond to calls based on various factors, including the number of cars available and their current locations.

The other options, while related to elevator operations, do not specifically define the function of directing traffic in the lobby. A starter's panel is generally associated with the initial power-up and control functions of a motor or system but lacks the specific traffic management capabilities of a lobby controller. An elevator hub usually doesn’t represent a singular panel, and the controller panel typically refers to the central operating system for the elevators rather than the public interface located in the lobby.
