Myriad II - Integrated Crowd Dynamics Modelling Suite
Over the last 15 years we have been using a range of modelling and analysis techniques for places of public assembly. The process of model building typically requires three different mathematical modelling disciplines. The table below shows how these methods overlap for various projects.

Uses of Crowd Dynamics Software around the world
UK Cabinet Office Emergency Planning College - Workshops
London New Year Fireworks (Real-Time Decision Support)
Wide Area Evacuation (Real-Time Decision Support and information system)
DWELL Time models - train loading/unloading under high density conditions
Below - Agent Analysis - users import CAD plans and can run agents through complex spaces.
Above and below - agent analysis - dynamics zoom, large scale modelling and local geometric analysis
Below - network analysis tool - create a network quickly to test the macroscopic flow characteristics of complex spaces. Enter widths of road, areas and capacity information. Create a time related flow entering the network and observe the flow of the crowd through the system. Rapid prototyping from CAD plans in minute.
Below - coloured areas indicate the optimal capacity flow for the various possible exits in the system.
Using Myriad you can move from CAD to Egress Analysis in a few minutes. Everything from desks to districts can assessed using Myriad.

We have updated the modelling capability to include 3D views. multiple threats and dynamic route capacity analysis. Nodes, areas, links, routes and flow rates are all defined and propagated through the network created in the Myriad II software.
Myriad was used to test the pedestrian plans for the 2006/7 London New Year Celebrations along the Thames.
We also developed a real-time command and control (decision support and audit trail) systems for other Policing events.
