Passenger flow forecasts 24 hours in advance


SITA FlowPredictor provides highly accurate passenger flow forecasts for the next 24 hours, enabling proactive management of the airport environment. Forecasts are performed continuously, always using the current situation in the airport, and reflecting any change within minutes when updating forecasts.

FlowPredictor allows “what if” scenarios, as well, allowing users to execute validation forecasts before deciding to take specific actions.

This product is available through SITA's ATI Cloud.

How it helps

SITA FlowPredictor allows airport operators to identify and predict flow challenges in real-time. Changes in flight schedule (e.g., delays in arrivals and departures), as well as preventive or corrective measures (e.g., changes in gates or allocation of resources), are possible 24 hours in advance.

As a component of our Day of Operations BI (Business Intelligence) solution, FlowPredictor utilizes SITA’s unique BI portal (AirportPulse) to provide key performance indicator (KPI) dashboards and a single point-of-access to services, culminating in complete, end-to-end situational awareness across the airport.

Key features

  • Data collection & integration – real-time and forecasted passenger data is analyzed in relation to specific points of interest within the terminal
  • Passenger flow simulation – new simulations are run within 1 minute when input data changes to ensure predictions are always up-do-date
  • What if scenarios – qualify effects beforehand to enhance decision-making
  • Optimization – parameters show the number of resources needed to keep service level agreement (SLA) stable
  • Visualization – heat-maps, process-point overviews, 2D and 3D terminal views


  • Optimized revenues
  • Reduced costs and planning buffers
  • Improved resource allocation due to proactive (vs. reactive) decision-making
  • Increased capacity without capital investment for terminal expansions due to optimized use of existing infrastructure
  • Enhanced collaboration
  • Better situational awareness

Why us?

While tools such as CCTV and measurement systems identify long queues and wait times after the fact, SITA FlowPredictor allows airports to avoid them before they can occur. Only FlowPredictor forecasts passenger flow in the future.

FlowPredictor’s powerful simulation engine and modeling module provide forecasts such as:

  • Agent-based passenger behavior simulation model
  • Multi-level terminal layout – editable by user
  • Support per service point – security, border control, boarding-pass check, etc.
  • Different distributions (e.g., Weibull, Normal) for simulation parameters – process times, walking speed, arrival rates, etc.
  • Changes in capacity at service points based on staff schedules
  • Adaptive resource capacity when schedules are not available
  • Alternate routes for passengers through terminal
