MassMotion Consulting
See the Crowd Before You Build the Building.
SimWell helps design teams, transit authorities, and facility owners build, validate, and defend MassMotion pedestrian models that support capital decisions, safety reviews, and regulatory submissions.
Why SimWell for MassMotion
MassMotion produces realistic pedestrian behavior. Turning that behavior into evidence that supports a capital decision, survives a safety review, and earns stakeholder trust requires modeling discipline, validation rigor, and documentation that the software alone cannot provide. SimWell brings that discipline to every MassMotion engagement.
Where SimWell goes beyond a working model
- Model architectures scoped to the decision: concept selection, safety review, bid defense, or operational planning
- Validation against design inputs, safety criteria, and comparable benchmarks your reviewers will accept
- Documentation packages built for owners, regulators, and code consultants, not just the modeling team
- Scenario libraries structured around the questions that recur across design phases, not just the one that triggered the study
- Training that helps architects, engineers, and planners interpret and extend MassMotion results through real project work
MassMotion lets us walk owners, architects, and safety reviewers through a design that already behaves like a real station. The simulations turn layout choices into evidence that stands up in meetings, submissions, and audits.
André Jacques CTO, SimWellWhy MassMotion
MassMotion gives design teams a behavioral model of crowd movement inside complex environments. When the decision involves how thousands of people circulate, queue, evacuate, and interact inside a station, terminal, or public space, MassMotion delivers the evidence that static drawings and manual calculations cannot provide.
Agent-Based Pedestrian Simulation
MassMotion models individual pedestrian behavior with collision avoidance, wayfinding, and behavioral rules. Thousands of agents move through multi-level environments under realistic demand conditions. Architects, engineers, and planners see how people actually behave inside their design, including crowding, queuing, and congestion that floor plans alone cannot reveal.
Validated Evacuation and Egress Analysis
MassMotion supports verified evacuation modeling aligned with IMO 1238 and NIST 1822. Design teams test clearance times, identify bottleneck locations, and generate the evidence required for safety reviews and regulatory submissions. Results hold up when owners, code consultants, and regulators ask for proof.
BIM-Native Workflows
MassMotion imports geometry from IFC, Revit, AutoCAD, MicroStation, Rhino, SketchUp, ARCHICAD, and Vectorworks. The model stays aligned with the current design set throughout the project lifecycle. When the design evolves, the analysis updates without a full rebuild.
Scenario Modes for Different Decision Types
MassMotion runs four scenario modes: Journey, Circulate, Vehicle, and Evacuate. Each mode targets a different question. Journey evaluates point-to-point travel time and route choice. Circulate tests free-flow movement and dwell behavior. Vehicle models boarding and alighting. Evacuate measures clearance performance. Planners select the mode that matches the decision instead of forcing every analysis into one framework.
Heat Maps and Comfort Metrics
Density maps, level-of-service scores, and comfort analytics highlight where crowding exceeds thresholds before construction begins.
High-Performance Simulation
MassMotion remains stable with hundreds of thousands of agents in long-duration scenarios. Large transit hubs and event venues run at full population without simplification.
3D Visualization and Stakeholder Playback
MassMotion Viewer provides 3D playback for owners, architects, and safety reviewers who need to see behavior, not read a report.
How we work together
Every SimWell engagement delivers something usable early and builds from there. Four entry points, depending on where your team is starting.
Your team wants to apply pedestrian simulation but needs help identifying the right decisions to model and the right level of fidelity for the project phase.
Your team has MassMotion licenses and wants to build internal capability with structured guidance from working modelers.
You want to build internal capability and ship a working model on the same engagement.
You need a full decision tool, scenario library, or ongoing planning capability scoped to your supply chain environment.
SimWell & MassMotion
Technical depth
Expand each section for integration patterns and modeling detail relevant to internal modelers, BIM coordinators, and IT stakeholders.
Data Integration
Connect MassMotion to OD matrices, transit schedules, and facility management data for scenario-driven analysis. Use Excel and CSV imports for rapid scenario comparison. Pull demand profiles, timetable data, and design parameters into the model without manual re-entry. SimWell has integrated MassMotion models with transit planning systems, design-set exports, and BI platforms across client engagements.
BIM and Geometry Import
Import IFC, Revit, AutoCAD, MicroStation, Rhino, SketchUp, ARCHICAD, and Vectorworks geometry directly into the MassMotion environment. The 3D representation becomes both the simulation environment and the validation surface. Stakeholders review the model visually against the current design set and catch discrepancies before the analysis begins. SimWell maintains alignment between the model and the design as revisions move through the project lifecycle.
Custom Logic and Agent Actions
MassMotion's Agent Actions handles branching logic, custom agent behaviors, and decision triggers that fall outside standard scenario modes. The SDK and scripting layer extend the platform for edge cases requiring programmatic control. SimWell manages the custom logic layer in most client engagements and covers Actions Manager essentials in training for teams planning to maintain models internally.
Validation and Calibration
SimWell uses design inputs, safety criteria, and comparable benchmarks as the calibration baseline. Validation targets include travel times, density levels, clearance times, and queue formation compared against design standards or observed performance at comparable facilities. Edge cases receive explicit treatment rather than smoothed assumptions. Model behavior traces back to the underlying logic when reviewers question results.
Questions buyers ask before they engage
Do we need simulation experience to use MassMotion?
No. MassMotion's visual interface and scenario modes handle most analysis workflows without programming. When custom logic is needed, SimWell manages the Actions Manager and scripting layer in most engagements. If your team plans to maintain models internally, our training programs cover the capabilities your modelers will actually use.
What if we are not sure MassMotion is the right tool for our project?
Start with a Discovery Workshop. SimWell defines the decision, assesses the modeling requirements, and recommends the right tool and approach before any build begins.
Can SimWell work alongside our internal modelers?
Yes. The Coach the Modeler engagement supports teams who build models in-house and want expert review at key points. Custom Projects often run as embedded engagements where SimWell modelers work alongside internal teams through real project delivery.
Can the model evolve after the initial study?
Yes. A one-time MassMotion analysis strengthens design decisions, bids, and safety submissions. After a facility opens, that same model can evolve into a planning tool that updates when schedules, origin/destination matrices, or layouts change. SimWell supports the transition from project deliverable to operational planning asset.
