Passenger flow automation: lessons from the Viracopos case study

Passenger flow automation has become the primary driver of transformation in modern airport infrastructure, enabling operators to respond to demand peaks with greater precision and less friction. At Viracopos International Airport (VCP) in Campinas (SP), the implementation and expansion of automated border control systems demonstrated in practice how technology can redefine traveler processing. The upgrade reduced the wait time for a typical group of 200 passengers from 30 to just 10 minutes—a 66.6% speed gain that sets a benchmark for terminal management in Brazil.

Historically, bottlenecks in international terminals have been concentrated in document verification and border control stages. When operated strictly manually, these checkpoints require extensive physical sizing and massive staff allocation, factors that constrain operational flexibility. The Viracopos case shows that the path to unlocking capacity does not necessarily require physical expansion of built-up areas, but rather increased technological density and digital synchronization of ground processes.

What passenger flow automation is and how it works

Passenger flow automation in immigration control environments consists of the integration of smart electronic gates (known as ABC Gates or *e-gates*), machine-readable travel document (MRZ) optical readers, and high-precision facial biometric engines. The central objective is to decentralize and expedite traveler eligibility verification while maintaining rigorous public security and regulatory compliance standards.

The operational processing cycle in these systems occurs in sequential and standardized stages:

1. Document reading and validation: The passenger places their e-passport on the optical reader, which authenticates the document's security features and extracts the alphanumeric data and cryptographic chip.
2. Real-time biometric capture: High-resolution cameras capture the user's facial image directly at the checkpoint under controlled lighting conditions.
3. Biometric matching (1:1 Match): The algorithm instantly compares the captured image against the photograph stored in the passport chip or integrated government databases.
4. Physical release: Once identity and clearance are confirmed, the physical gate opens automatically, completing passage in a few seconds.

At Viracopos, the technology allows each individual gate to process up to six passengers per minute. Currently, e-gates are available to native or naturalized Brazilian citizens, while foreign travelers continue to use the conventional Federal Police service counters.

The operational engineering of the Viracopos case study: terminal capacity expansion

The modernization of Viracopos' International Passenger Terminal involved the installation of nine new automated biometric inspection units, strategically distributed across critical terminal areas: three units dedicated to international departures and six units dedicated to international arrivals. Prior to this deployment, the airport operated with only three legacy systems (one at departures and two at arrivals).

This expansion from three to nine automated checkpoints tripled the supply of fast-track processing lanes. More than just a numeric gain, the intervention represented a re-engineering of terminal capacity sizing:

• Tripled Throughput: The combined theoretical throughput capacity of the new gates reaches up to 54 passengers per minute at peak operation.
• Drastic Reduction in Dwell Time: Average processing time per international flight dropped by two-thirds, mitigating passenger congestion in sterile waiting areas.
• Spatial Optimization: The project enabled increased processing capacity within the existing terminal footprint, eliminating the need for costly structural expansion works.

As highlighted by the project's technology partners, such as SITA and Digicon, densifying technology in airports designed in earlier aviation cycles unlocks latent operational capacity, maximizing return on existing built assets.

The role of airport e-gates in resource optimization and security

The introduction of airport e-gates directly impacts the redistribution of specialized staff. By automating routine verification for low-risk passenger profiles (such as domestic citizens with regular documentation), the technology relieves the operational burden on Federal Police personnel.

Consequently, law enforcement officers can focus their attention and technical expertise on in-depth screening, border intelligence, and scenarios requiring discretionary manual intervention. This elevates the airport's security standards through risk-based assessment and targeted automation.

The Viracopos initiative was developed by the concessionaire Aeroportos Brasil Viracopos alongside SITA, Digicon, the Federal Police, and the National Civil Aviation Agency (ANAC). The project complies with the regulatory guidelines of the Federal Police Department ordinance published in the Official Gazette on July 17, 2025, which established timelines and specifications for border automation in Brazil.

Airport queue management and the impacts on airport operational efficiency

Airport queue management is one of the most critical variables influencing perceived passenger service levels and flight punctuality. Long and unpredictable immigration queues create ripple effects that undermine airport operational efficiency, including:

• Aircraft boarding delays (*pushback delays*) caused by passengers held up at outbound border control;
• Overcrowding in departure lounges and baggage claim halls, disrupting internal circulation flow;
• Drop in non-aeronautical revenue, as passengers who spend more time in queues have less time available in retail and dining areas.

By stabilizing the processing rate at up to six passengers per minute per gate, Viracopos not only eliminated immigration bottlenecks, but also made the terminal flow curve predictable for the Operational Control Center (OCC). This predictability allows for aligned ground staff scheduling, apron stand allocation, and aircraft sequencing based on accurate passenger movement data.

Guidelines for implementing passenger flow automation in airports

For airport operators and concessionaires seeking to replicate the productivity gains observed at Viracopos, implementing automated flow systems requires a technical approach structured across four key pillars:

1. Systemic integration and regulatory compliance

Biometric control systems and e-gates must be fully integrated into the data ecosystems of regulatory and law enforcement agencies (such as ANAC and the Federal Police). Adherence to cybersecurity and data governance protocols is a mandatory prerequisite for platform authorization and operation.

2. Dynamic layout sizing

The physical layout of e-gates must account for passenger desire lines, queue accumulation areas with proper stanchions, and intuitive visual signage. The goal is to prevent the access queue for automated gates from blocking the flow of passengers heading to conventional counters.

3. Redundancy and local technical support

Mission-critical equipment demands stringent Service Level Agreements (SLAs), local spare parts inventory, and immediate switchover capabilities to assisted or manual operation during network fluctuations or mechanical failures.

4. Real-time data intelligence

Capturing real-time metrics (such as gate occupancy time, biometric rejection rates, and throughput per minute) must feed terminal operational management systems, enabling dynamic interventions by customer service teams.

Conclusion: smart infrastructure as the future of aviation

The Viracopos International Airport case demonstrates that expanding airport capacity in Brazil relies primarily on the technological modernization of terminal processes. By reducing immigration transit time by 66% through biometric e-gates, the airport not only enhanced passenger experience, but also optimized operating costs and maximized the throughput of its existing facilities.

As air traffic grows and on-time performance requirements become stricter, concessionaires and regional operators need tools that unify data intelligence from terminal to apron. Advanced operational management and intelligence platforms, such as those developed by Auter, empower airports to monitor resources, forecast operational bottlenecks, and make data-driven decisions in real time, transforming traditional infrastructures into high-efficiency hubs.
