MassMotion is designed from the ground up to provide you with the tools and information you need to make your designs better.

MassMotion has quickly become the pedestrian simulation software of choice for engineers, architects and infrastructure managers worldwide. Not only is it regarded as one of the most intuitive tools of its kind, but it is calibrated to industry standards and offers unparalleled simulation speed. MassMotion has played its part in urban infrastructure and transport hub projects globally and has been instrumental in establishing 3D pedestrian simulation as a necessary element of infrastructure projects of any size.

Support for all the leading file interchange formats ensures that MassMotion works seamlessly with information generated in any CAD programme. 3D and 2D assets, created in different CAD programmes can be imported and combined to create a single MassMotion model.

Agent dynamics and how they are as near to real life as possible

MassMotion quickly reveals the way that crowds will move through a building as they encounter stairs, doors, ticket gates, each other and many other objects. The agents have been described as offering analyses that are as near to real life as is possible. The software itself does not determine what agents do: their behaviour is based on decades of academic research and social modelling. MassMotion gives the agent an individual agenda, to get from A to B – each of whom will have their own agenda and will respond to changes in real time. For example, they may choose to take the stairs when faced with congestion at an escalator, or join the queue for a turnstile that has just switched from closed to open.

Now, with MassMotion version 9.0 you also have the tools to tailor the built-in algorithms and define triggers such as crowd density, time of day, lack of seating or a complex combination of conditions. The personality (properties) of agents can also be individually adjusted to suit your requirements, such as having defined groups of agents with fast-track tickets that allow them access to specific doorways, routes or queues. Even the feeling of hunger can be assigned, prompting the agent to search for food outlets within the model.

Scalable and customisable analysis tools

MassMotion uses a high-performance database to store and retrieve simulation results, you can call on a variety of built-in graphing, mapping and filtering tools to provide you with clear information about crowding, usage patterns and occupant safety in a facility.

This methodology is highly scalable for very large crowds and for simulation scenarios that cover multiple days. Leveraging the 3D capabilities of MassMotion, the analysis system enables users to develop custom analysis based on spatial, temporal, operational, and personal characteristics of people and their environment. It is also possible to combine multiple result sets at the same time and view as a single analysis. All this can be presented as visually engaging, tabular and data-driven graphs and visuals.

The analysis highlights points of congestion and its 3D visualisations reveal opportunities for improvement. What’s more it does all of this remarkably quickly – once the model is built, analyses can be run in minutes or hours with little or no additional programming. Designers and engineers have the information they need to move forward with a project. Testing alternative scenarios becomes easy, economical, and risk free. MassMotion saves time, money and manpower during planning, construction and operational phases of a building lifecycle.

MassMotion Software Development Kit

The industry’s first software development kit enables MassMotion users to have complete control over the advanced algorithms used, the simulation and the agents within. Used widely within Universities for research purposes, it will help you create an environment that fits your exacting requirements. The SDK is available to all maintained MassMotion users.

Real 3D and why it matters

You work with both 3D and 2D CAD as part of a BIM workflow, so does version 9.0. Import your 2D CAD files and then build into 3D models allowing you to observe your model more effectively than ever before. You no longer need to render a 2D image in 3D that requires your multi-level structure to be linked with linkages between separate models for each level in order to simulate pedestrians moving between them. The journey between these areas is often just as important as what happens within them – and just as likely to be the source of congestion and inefficiencies that designers and engineers seek to eliminate through simulation. Only 3D modelling shows designers the entire pedestrian experience.

That’s not all either, MassMotion visualisations are working design and analysis tools, not just a means of stakeholder communication as you would find when using an animation software package.

Native high-quality real-time 3D graphics, direct image/video capture and straightforward data export give users the power and flexibility to building diagrams, animations and presentations with ease.

MassMotion evacuation modelling validation

A recent research project in collaboration with Carleton University was conducted in order to validate the use of evacuation modelling using MassMotion. This paper critically examines a fire drill performed in 2016 at a retirement home in Canada and provides insights and guidance into modelling elderly populations, both in general and situations specific scenarios. 

The data collected during the drills was then used in comparison with associated evacuation modelling results using MassMotion to create a validation case study. The research paper has since been presented at the Interflam 2016 conference and will be presented at PED2016.

We have found it to be intuitive and flexible. The thing that particularly impressed us was the simulation speed. We were able to run a large number of models much more quickly than we have been able to do with other packages.  –  Alan Kerr - Technical Director, BECA

MassMotion was really important in planning how we kept the station running smoothly during Renovations. We needed to make sure that we understood the way passengers were moving around the station so we didn’t run into any crowd control issues."  –  Steve Lewis - Network Rail

We have been using MassMotion for a good couple of months and we are very happy with the product. Having this tool has started to open up additional services to clients that we previously did not have and we are hoping that it will continue to grow.  –  Andrew - SERECA Fire Consulting
