A look at real-time queue monitoring enabled by computer vision

Discover how computer vision for queue monitoring can track movement, predict congestion, and optimize queue flow in real-time across various industries.

What if managing long queues at theme parks, restaurants, and airports could be seamless? No more frustrated customers, no more overwhelmed staff - just smooth, efficient, fast-moving lines. Traditional queue management relies on techniques like manual counting, sensors, and outdated surveillance systems. These methods can lack precision and slow down operations, leading to longer wait times and inefficiencies.

This can affect business operations since long waiting times drive customers away. Studies show that 73% of customers abandon their purchase if the wait time in a queue exceeds five minutes, making it increasingly challenging to manage demand and optimize resources. However, thanks to advancements in AI and computer vision, we now have more innovative solutions.

In particular, computer vision is a branch of AI that enables machines to interpret and respond to visual data. Computer vision models like Ultralytics YOLO11 can help deliver faster, more precise results by analyzing visual data.

In this article, we’ll explore how Ultralytics YOLO11 can be used for queue management, its real-world applications, and the key benefits it brings.

An overview of AI-powered queue management

Typically, queues are managed through manual counting or basic sensor systems. For example, at an airport security checkpoint, staff might count passengers or use simple sensors to estimate wait times. Relying on these periodic checks and historical data, they decide when to open another lane.

In contrast, Vision AI-powered queue management uses real-time data from cameras that capture continuous footage. This footage is analyzed instantly using computer vision models like YOLO11. These models support various tasks, such as object detection and object tracking. With insights from Vision AI solutions, managers can quickly adjust staffing or open additional service points. Real-time insights and faster actions based on them can lead to shorter wait times and a smoother, more efficient experience for everyone.

Understanding real-time queue monitoring with Ultralytics YOLO11

Here’s a closer look at how YOLO11 can be used to monitor a queue:

  • Video input: A camera captures live footage, which is split into individual frames.
  • Defining the queue area: A specific area (the queue region) is marked where the system should focus, reducing errors from irrelevant activity.
  • Detecting people: YOLO11’s support for object detection can be used to scan each frame to find people, drawing boxes around them and labeling each one.
  • Tracking movement: Each detected person is given a unique ID, and their movement is followed from one frame to the next by tracking the center of their box using YOLO11’s object-tracking capabilities.
  • Analyzing the queue: The system counts the number of people in the queue and tracks how long they wait, alerting staff when the queue gets too long.

Applications of smart queue management systems

Now that we have covered how YOLO11 can be used for queue management, let's explore its real-world applications and see how various industries are using it for efficient crowd management.

Retail queue optimization with YOLO11

Long checkout lines don’t just test a customer’s patience; they impact sales. Abandoned carts and overcrowded counters are common frustrations in retail stores. To keep things moving, stores can adopt smarter ways to track queues in real-time and act before bottlenecks form.

Beyond simple queue monitoring, computer vision and YOLO11 can be used to tell the difference between customers who are actually waiting and those who are just passing through, browsing, or stepping away briefly. 

For example, Vision AI can be used for the speed estimation of a customer. By analyzing how fast someone is moving, the system can determine whether they're actually waiting in line or just passing by. 

It can also help track individuals who step away and then return to the queue, ensuring they're still counted, and spots when new customers join the line. These insights provide a clear picture of the queue's length and congestion, making it easier for retailers to manage wait times.

Using computer vision for queue monitoring at airports

With more people traveling than ever, airports are getting busier and more crowded. Long security lines, packed terminals, and congested boarding gates can be inconvenient. Managing these high-traffic areas efficiently is a vital part of keeping things running smoothly and ensuring a stress-free travel experience.

To tackle these challenges, many airports are adopting AI solutions for queue management that do more than just predict wait times. For example, when obstructions are detected, Vision AI systems integrated with YOLO11 can alert airport staff to take immediate action, such as redirecting passengers to alternative security checkpoints, deploying mobile security teams to clear blockages, or dynamically adjusting boarding gate assignments to alleviate congestion. Computer vision can also be used to measure crowd density and detect congestion patterns to improve overall airport operations.

Queue management with AI for banks and financial institutions

Even with the rise of digital banking, physical branches continue to experience overcrowding, especially during peak hours or on specific days of the month. Long wait times at teller counters and service desks can lead to customer frustration and operational inefficiencies.

AI queue management enabled by YOLO11 can help banks monitor and predict customer wait times for streamlined operations during peak hours. On top of this, the same camera footage used for queue monitoring can be repurposed for enhanced security and surveillance, boosting overall safety and operational insights. For instance, computer vision can be used to quickly detect unusual behavior or unauthorized access, alerting staff to any issues.

Smarter queue management for events 

Large-scale events and stadiums attract massive crowds, making efficient crowd management essential. Whether it’s a concert, sporting event, or a festival, managing the entry and exit of thousands of attendees can be challenging. Long queues at security checks, ticketing booths, and concession stands often lead to delays.

Real-time people counting and occupancy tracking with YOLO11 make it possible for organizers to guide attendees to less crowded areas. Queue lengths can also be dynamically managed at entry gates, concession stands, and restrooms, reducing wait times and improving the fan experience. 

In addition to this, these systems boost safety by continuously monitoring crowd density, making sure that security protocols are followed, and improving emergency response efforts.

Pros and cons of queue management

Now that we have explored various real-world applications of using YOLO11 for queue management, let’s take a quick glimpse at some of its benefits:
