A national transportation authority managing 45 transit hubs including airports, railway stations, bus terminals, and highway toll plazas was struggling to maintain security and operational efficiency across its network. The authority processed over 2 million passengers daily, yet its surveillance infrastructure consisted of disconnected CCTV systems at each location with no centralized monitoring capability. Security incidents at transit hubs had increased by 18% year over year, crowd management during peak hours was entirely manual, and toll collection on highway corridors suffered from revenue leakage due to inaccurate vehicle identification. The authority needed a unified platform that could handle the scale and diversity of its operations.
Aptibit deployed Visylix across all 45 transit hubs in a phased implementation spanning five months. The platform was configured with specialized AI models for each environment: ANPR for highway toll plazas and parking facilities, crowd density monitoring for railway platforms and bus terminals, face recognition for airport security checkpoints and restricted areas, and person tracking for cross camera surveillance at all major hubs. A national operations center was established with live dashboards showing real time status across every location. Edge processing nodes were installed at highway toll points to enable sub second vehicle identification at speeds exceeding 120 km/h.

The Challenge: Securing a Nation in Motion
The national transportation authority is responsible for the safety and efficiency of 45 transit hubs that collectively serve as the backbone of the country passenger and freight movement network. These facilities range from international airports handling 50,000 daily travelers to regional bus terminals serving 5,000 commuters and highway toll plazas processing tens of thousands of vehicles every hour. Each facility had its own independently installed CCTV system, many of which were over a decade old and incapable of any analytics beyond basic recording.
Security was the most urgent concern. With rising passenger volumes and increasingly complex threat landscapes, the authority had recorded a steady increase in security incidents including unauthorized zone access at airports, crowd crushes at railway platforms during festivals, and vehicle related offenses on toll corridors. Manual crowd management relied on security personnel making visual estimates of platform density, a method that consistently failed during sudden surges caused by train delays or event traffic.
Revenue leakage at highway toll plazas presented an additional financial challenge. The existing license plate recognition systems had accuracy rates below 88%, resulting in significant numbers of vehicles passing through without proper toll deduction. The authority estimated annual revenue losses in the hundreds of millions attributable to missed or misread plates, especially during nighttime, rain, and high speed conditions.
The Solution: One Platform for Every Transit Mode
Aptibit designed a deployment architecture that could accommodate the vastly different requirements of airports, railway stations, bus terminals, and highway toll plazas within a single unified platform. Visylix modular AI engine allowed each transit hub to run the specific combination of models most relevant to its operations while sharing a common management layer and national dashboard.
At airport facilities, face recognition was deployed at security checkpoints, boarding gates, and restricted area entrances. The system matched travelers against authorized passenger manifests and flagged individuals on security watchlists in real time. Crowd density models monitored terminal lounges and baggage claim areas, providing airport operations teams with occupancy data used to open additional security lanes or redirect passenger flow before congestion thresholds were breached.
At railway stations and bus terminals, crowd detection models focused on platform safety. The system measured real time density on each platform segment and triggered alerts when occupancy exceeded safe thresholds. Digital signage integration allowed the operations center to display platform redistribution messages automatically. For highway toll plazas, Visylix ANPR engine was deployed with high speed camera arrays and infrared illumination, enabling accurate plate capture at vehicle speeds up to 150 km/h in all weather and lighting conditions.
National Operations Center and Edge Deployment
The national operations center was the nerve center of the entire deployment. Built on Visylix command center architecture, it featured a large format video wall displaying a geographic map of all 45 transit hubs with real time status indicators. Operators could drill into any facility to view live camera feeds, active AI alerts, crowd density visualizations, and ANPR event logs. Cross facility analytics enabled the operations team to identify patterns such as unusual passenger flow between specific stations or vehicles appearing at multiple toll points with mismatched plates.
Edge computing was critical for the highway toll plaza deployments where latency requirements were strictest. Each toll point received a dedicated Visylix edge processing unit that performed ANPR locally, ensuring that plate capture and matching occurred within milliseconds of a vehicle entering the detection zone. These edge nodes uploaded processed results to the central platform for billing, audit, and forensic purposes. The architecture ensured that toll operations continued uninterrupted even during temporary network connectivity issues between remote highway locations and the central data center.
Integration with existing ticketing and access control systems at railway stations and airports was accomplished through Visylix open API layer. This allowed the platform to correlate video events with ticket validation data, gate access logs, and flight manifests, providing a comprehensive view of passenger movements that was previously impossible to assemble.
Results: Safer Transit, Stronger Revenue
Within six months of full deployment, the transportation authority measured a 62% reduction in security incidents across all 45 transit hubs. The improvement was most dramatic at railway stations, where crowd density monitoring and proactive platform management virtually eliminated dangerous overcrowding events during peak hours. Airport security checkpoints reported zero unauthorized zone breaches following the activation of face recognition at restricted area entrances.
ANPR accuracy at highway toll plazas reached 99.1%, a substantial improvement over the previous system 88% rate. This improvement translated directly into recovered toll revenue. The authority reported that the increased collection efficiency covered the entire cost of the Visylix deployment within the first eight months of operation. Night and adverse weather performance, which had been the weakest point of the legacy system, improved most dramatically thanks to infrared illumination and Visylix weather adaptive image preprocessing.
The national operations center has become a model for centralized transit management in the region. Government officials from neighboring states have visited the facility to understand the deployment methodology, and Aptibit has been invited to submit proposals for similar implementations across two additional state transportation networks. The authority plans to expand the Visylix deployment to include predictive analytics for passenger demand forecasting and automated schedule optimization in the next phase.
