LEGION Model Builder
Perform models of any place where people converge
LEGION Model Builder is a simulation and modeling software that enables you to build a precise model of a space that can be simulated and analyzed based on a set of key inputs such as design, demand, and operational data. You can use LEGION Model Builder to run and evaluate virtually any place where people converge such as railway stations, sports stadiums, airports, office complexes, theaters, piazzas, and transport hubs.
LEGION Simulator
Better predict and improve pedestrian flow and safety
LEGION Simulator enables you to simulate people movement in order to explore various design alternatives. Its data-rich analysis output supports infrastructure assets that range from metro stations and airports to stadiums and shopping malls. With LEGION Simulator, you can accurately test designs and plans to enhance footfall, wayfinding, crowd management, safety, and security strategies. Get insight to make better decisions with visualization and predictions by combining planning information from the LEGION Model input file with the automated predictions of how people move. Evaluate and visualize traffic flows at a venue before it’s built, and explore a range of scenarios and make informed decisions–and trade-offs–by modeling and simulating up-front.
Build models for any type of venue

You can build models for any type of venue or building, such as sports facilities, urban and commercial buildings, and airports. Use automated routing, increased intelligence, and simplified objects to build and audit models. You can easily reus
Collaborate faster and more easily
When working with various project team members on tight timelines it’s important to have access to the most up-to-date data. LEGION offers a design environment that enables you and your team members to work on models simultaneously, regardless of their location, using a shared set of libraries and workflows. By being able to incorporate data from a wide range of open applications and geospatial formats, users can reduce time spent on re-work and manual data entry.

Technical capabilities
Build precise models
Build precise models
Create precise models of how a space will be used
- Import architectural drawings (CAD) to define physical spaces available for pedestrian use
- Specify the anticipated pedestrian demand for the space
- Designate areas where interim activities, such as queuing or waiting, occur
- Link operational data to the model
- Plan routes and automatically lay out navigation maps
- Populate the model based on activities and characteristics, such as size, speed, and personal preferences.
Principle of Least Effort
- Uses the concept of least effort, or least cost, as the basis of pedestrian logic
- Dissatisfaction is caused by physical and psychological factors that lower journey quality. Factors that contribute to dissatisfaction:
- Inconvenience – desire line divergence stress
- Discomfort – personal space compression stress
- Frustration – preferred speed relinquishment stress
Unbounded Movement Choice
The ability to adjust individual preferences and attributes
Model space is continuous, rather than structured, based on a pixel grid
Select any vector when optimizing step choice to satisfy individual preferences and objectives in the context of changing physical constraints
This approach follows a two-stage process:
- Macro-navigation
- Micro-navigation
Intelligent Entities
- Social, physical, and behavioral characteristics are assigned probabilistically from established profiles
- Social characteristics include gender, age, culture and pedestrian type, all of which shape typical movement preferences
- Physical characteristics determine body sizes
- Behavioral characteristics include memory, adaptability, and preferences for unimpeded walking speeds, personal space, and acceleration
Output and Analyses
Heat maps provide intuitive overviews to help identify areas requiring deeper analyses, including line graphs, histograms, stacked histograms, cumulative data, or even raw data, which can then be used for statistical analyses
Numerical and graphical outputs derived from a model and user-defined areas, interrogated to provide user-defined combinations of these, based on user-defined thresholds
Measure and quantify the performance of a site with respect to experience, circulation, and safety
Key metrics include counts, flows, distances, densities, journey times, speeds, and levels of service
