And How BluBØX Fixes It with Intelligent Turnstile-Based Dispatching

One of the most common mistakes made in designing integrated security and elevator systems—by architects, security consultants, elevator consultants, integrators, and even building owners—is automatically dispatching elevators at the turnstile based on a person’s default floor.

On paper, this sounds efficient. In reality, it’s a performance killer.

The Problem with Default-Floor Dispatching

Studies show that 25% or more of people do not go to their default floor when they enter the building. Post-COVID workplace changes—like hybrid work, flexible schedules, and hoteling—have made this even worse. In some buildings, 50–70% of employees go to different floors every day.

Here’s what happens:

• A person taps in at the turnstile.
• The system automatically dispatches them to their default floor.
• But the person is actually going to a different floor.
• So they walk to the kiosk and manually request the correct floor.

Now the system has two calls:

• One to the wrong floor.
• One to the right floor.

This creates “ghost calls”—unnecessary elevator trips that degrade system efficiency. The elevator system still has to process and respond to that initial call—even though it’s not used. Over time, this overwhelms destination algorithms, delays service, and hurts overall vertical transportation performance.

The BluBØX Solution: Intelligent Dispatch at the Turnstile

At BluBØX, we’ve reimagined this process by embedding Person Readers at the turnstiles and using AI to make smarter dispatching decisions.

Here’s how it works:

• The Person Reader identifies the individual and learns their floor behavior over time.
• If a person always goes to the same floor, BluSKY dispatches automatically—no friction.
• If the person frequently goes to different floors, the system asks them for their desired floor at the turnstile.

Once input is given, BluSKY makes a single, correct elevator call—no ghost calls, no duplicates.

The Result: Perfect Calls, Perfect Timing

• Every call at the turnstile becomes a precise match to the person’s actual intent:
• Elevators are dispatched only when needed.
• Destination algorithms are accurate and efficient.
• The time to travel is reduced by 10–15 seconds per trip.
• Riders experience a seamless flow: tap at the turnstile, input destination (if needed), walk to the assigned elevator—and it’s already there.

Real-World Impact

Buildings running BluBØX’s Person Reader system consistently report:
• Faster elevator arrivals
• Fewer delays and bottlenecks
• A smoother, smarter vertical experience

If you want maximum elevator efficiency, minimum wait times, and a better tenant experience, it’s time to retire default-floor dispatching. Upgrade to BluBØX’s intelligent turnstile dispatching—and eliminate ghost calls for good.
