Why Default Floor Dispatching Is Killing Your Elevator Efficiency

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.
