Advanced pedestrian simulation and analysis software

MassMotion has quickly become the crowd simulation software of choice for organisations worldwide. The software provides industry leading tools to import and combine all of your 2D and 3D workflow assets to quickly build a 3D simulation. You can introduce a defined number of agents (virtual pedestrians) who will travel around your model intelligently according to your specific requirements.

Test an unlimited number of designs and determine which design provides the most comfortable and efficient journey for the users using MassMotion’s advanced analysis tools and visualisations. Ideal for transport hubs, any sort of scheduled event, airport terminal design and planning, advanced evacuation planning, offshore platforms, and stadia planning and maintenance projects.

How MassMotion Works

MassMotion’s 64-bit multi-threaded design takes full advantage of multi-core processors and system memory, allowing you to model huge crowds. There are many aspects of the software that make it an attractive proposition for any company involved in facility design or operations planning. MassMotion’s ability to model emergent crowd behaviour makes it invaluable for exploring solutions.

Its robust validation and verification makes it incredibly reliable and accurate. The software also has a rich feature set to enable its users to simulate environments that are defined using BIM or other 3D modelling tools. Finally, MassMotion reports in a variety of ways, with visually engaging 3D graphics, charts and tabular data-driven outputs because communicating results is vitally important.

Key Benefits
