MassMotion
Pedestrian dynamics and evacuation simulation software that models 3D crowd movement, circulation, and emergency egress scenarios -- used by fire protection and life-safety engineers to validate egress code compliance, analyze occupant flow under fire conditions, and optimize emergency response; features adaptive agent-based modeling, automatic way-finding, occupant demographics, and scenario testing; developed by Oasys (part of Arup).
C1 3/5 reflects quote-only pricing on a quote-request basis, and C2 3/5 reflects a software development kit (SDK) enabling custom integration and algorithm control, though no public REST API or CLI. C4 4/5 reflects .fbx, .ifc, .dwg import with multiple output formats (tables, heatmaps, graphs), and C5 4/5 reflects BIM workflow integration via IFC and custom SDK access. Verified per IMO 1238 and NIST Technical Note 1822 standards.
