• A. Highrise Office Tower
• B. 4-Story University Laboratory
• C. Department Store
• D. 4-Story Apartment Building

Answer: (A)

Destination Dispatch works by routing riders to the elevator car that serves their destination floor before they enter, grouping passengers by destination to minimize stops. This reduces both waiting time and total travel time by preventing cars from stopping at many unrelated floors and by balancing trips across multiple elevators. This approach shines in a tall building with heavy, concentrated traffic across many floors—typical of a high-rise office tower. In such a setting, hundreds or thousands of people move between a wide range of floors during peak hours, causing long queues and inefficient, stop-heavy trips with traditional elevators. Destination Dispatch significantly improves throughput by quickly assigning riders to the most appropriate car, cutting waiting times and travel through the building. In shorter buildings or places with simpler floor-to-occupant patterns—like a four-story facility, a department store, or a small apartment building—the benefits don’t scale as dramatically, so the system isn’t as essential or impactful.
