Public Queue Management with Facial Recognition Using Computer Vision
Managing crowds efficiently and securely is a critical challenge for many public spaces, from large-scale events like concerts, festivals, and places of worship to transportation hubs and offices. Traditional methods often struggle to cope with the volume and complexity of modern gatherings, leading to long wait times, security vulnerabilities, and, in extreme cases, crowd disasters like stampedes.
Recent incidents highlight better crowd and queue management solutions. In January 2025, a stampede at the Maha Kumbh Mela resulted in multiple fatalities as millions of devotees overwhelmed existing crowd control measures.
Similarly, at the Tirupati Temple, an uncontrolled surge of worshippers led to at least six deaths and dozens of injuries. Despite CCTV surveillance, these tragedies demonstrate that traditional crowd-monitoring solutions are insufficient.
Facial recognition using Computer Vision for public queue management provides a better solution to these challenges by automating entry and exit processes, offering real-time crowd insights, and enhancing security. Queue management also involves real-time tracking of devotees and visitors to monitor movement patterns and manage crowd flow dynamically, along with surveillance-driven security to detect risks before they escalate.
This blog explores how facial recognition, real-time tracking, and surveillance-driven security enhance public queue management, examining their benefits, addressing privacy concerns, and showcasing real-world implementations.
Challenges in Public Queue Management: The Need for an Advanced Approach
Public events and places of worship frequently draw massive crowds, making queue management a critical operational concern. Traditional methods, relying on manual checks, physical barriers, and static queuing systems, often struggle to deliver efficiency, security, and a positive attendee experience. This leads to a range of challenges:
- Prolonged Wait Times and Inefficiencies: Manual ticket verification, ID checks, and security screenings create bottlenecks at entry points, causing frustration and congestion. Peak hours at religious sites or large events exacerbate these issues, impacting visitor’s experience and operational flow.
- Lack of Real-Time Queue Monitoring: Traditional queuing systems cannot track queues in real time, hindering the prediction and management of crowd movement. Event staff struggle to address bottlenecks effectively and guide attendees to available entry points without automated queue monitoring.
- Security Vulnerabilities: Reliance on manual security checks increases the risk of unauthorized access, ticket fraud, and security breaches. Ensuring only authorized individuals enter restricted zones is nearly impossible in large gatherings without automated identity verification.
- Limited Accessibility and Queue Personalization: Public queues often fail to adequately accommodate specific attendee needs, such as elderly worshippers, individuals with disabilities, or VIP guests. This lack of personalized queue management can lead to discomfort and inefficient entry processes.
- Minimal Data Insights: Traditional queue systems provide little to no data on entry times, visitor flow, or congestion points. Optimizing queue management becomes a reactive rather than proactive process without real-time and historical data.
- Scalability Challenges: As event sizes and religious congregations grow, traditional queue management methods struggle to scale effectively. The absence of automated tracking and AI-driven adjustments can lead to operational breakdowns, overcrowding, and inefficiencies in handling large numbers of attendees.
- Entry and Exit Tracking Issues: Traditional queue management systems lack real-time monitoring of individuals entering and exiting a venue, leading to inaccurate attendee counts, overcrowding, and security risks. Without an efficient tracking mechanism, unauthorized multiple entries can occur, making it difficult to control capacity and prevent safety breaches.
