CAST Terminal

Passenger Flow and Process Simulation Software

CAST Terminal provides scalable and realistic models of airport terminals and other passenger handling facilities. It enables decision support for planning, design, capacity analysis and optimization of terminal infrastructure and operational processes.

CAST Terminal is used to determine facility requirements and to validate new terminal layouts and processes in order to achieve maximum planning reliability at the earliest stage. Additionally, CAST Terminal provides great potentials to optimize the existing terminal facilities and processes within various operational scenarios.

CAST Terminal Simulation Software

With CAST Terminal, an entire airport or its individual parts can be investigated in detail in order to cost-effectively conduct analyses aiming at:

  • Planning of optimal and balanced terminal infrastructure
  • Identifying bottlenecks and testing mitigation measures
  • Analysis of Level of Service and ensuring highest passenger convenience
  • Identification of the most effective and cost-efficient operational concept
  • Support of tactical and strategic decision-making in airport operations and management

CAST Terminal improves the planning process, offers highest reliability and helps to achieve quicker results and better cost efficiencies by:


  • Providing a clear and understandable representation of all terminal processes
  • Reducing investment costs and risks
  • Utilizing it as a reliable testbed for new configurations (‘what-if’ experiments)
  • Speeding up and standardizing the terminal modelling & planning process
  • Dealing with uncertainties and predicting the impact of failures and changes
  • Avoiding planning mistakes
  • Easy communication to stakeholders
  • Quick return on invest

The user-friendly interface allows fast and straightforward modelling of complex structures as they appear in real world airport terminals.
Leading to most reliable results, numerous airport-specific parameters concerning facilities and passengers can be implemented. Besides the generation of relevant statistical data, the 3D visualization is an essential feature to convince decision makers.

Further features:

  • Flexible representation of terminal facilities (abstract or detailed)
  • Import of CAD layouts and various 3D object files
  • Flexible generation of passengers based on airport specifics and flight schedules
  • Analysis of various statistical data (e.g. LOS, queuing and waiting times, utilization rates, occupation level, etc.)
  • Realistic passenger behavior in circulation / waiting areas (crowding and queueing)
  • Pre-designed analysis templates for easy KPI extraction

CAST Terminal runs on standard PC or Laptop with Microsoft Windows. Flexible license models according to individual requirements.

Selected CAST Terminal Projects

Hundreds of CAST Terminal projects have been carried out by users around the world. The following projects give some CAST Terminal project examples that were conducted by the ARC consulting team.
Singapore Changi Airport
Terminal Capacity Analysis
So many different allocation options… A multi-scenario analysis by ARC identified the most promising way of operations, using CAST Aircraft and CAST Express. [...]
Oslo Airport Train Station
Simulation of Airport Rail Link
An airport causes high passenger volumes also at its train station. How can the passenger flow from train to terminal be optimized? [...]
APOC Simulation Platform
This project was carried out as part of the SESAR (Single European Sky ATM Research) initiative, as part of the focus area “Airport Operations Management”. It focused on the development [...]

Additional Consulting Services

To ensure a quick start and immidiate success ARC offers consulting services, training as well as support for the initial set-up of a model.
As an further option the Continuous Modelling Service (CMS) does not only include the set-up of a 3D-CAST model of the airport but also a predefined simulation service on a regular base in order to check defined airport parts or to test next season’s schedule. For ARC and its worldwide clients a close and long term cooperation is one of the most important key factors to ensure the best possible outcomes and ensure the sustainable use of the CAST technology.


Subsequent to the training experienced CAST experts take care of the user support. The ARC helpdesk is there to answer technical questions regarding the use of CAST for specific tasks, technical problems or special features of CAST. Further, individual modelling and project support is available as an option.


Being a CAST User means becoming a member of the CAST User Community. Every year, CAST users from various international airports, airlines and consulting companies come together to network with other experts, share experiences, talk about projects, gain insights into the latest developments and discuss CAST’s vision for the future.
