When a car with a "Selective Collective" controller receives an up call while moving to the lobby, what occurs?

In the context of a "Selective Collective" controller system, which is often used in elevators, the operation is designed to optimize efficiency by intelligently responding to calls based on the current direction of travel. When a car, already moving upwards toward the lobby, receives an up call, the system recognizes that the car is on its way to the destination where the call originated.

Instead of immediately stopping, which could disrupt the flow and efficiency of service, the controller decides to bypass the up call initially. This means that the car will continue its ascension to the lobby and only respond to the up call after reaching that position. This process helps ensure a more streamlined operation, minimizing unnecessary stops, and ensures that individuals heading in the same direction can be picked up effectively once the elevator reaches the lobby. This is particularly advantageous in buildings with high traffic, as it helps avoid delays and improve overall service efficiency.
