Crowd Dynamics - agent based Dwell analysis tool.
We have applied this for projects on the East London Line for Bombardier and Porterbrook. Currently using it on projects around the world where clients need to assess different train designs and platform performance.
The software modelling system imports a train/platform configuration and produces a dynamic test for DWELL for that specific configuration.

Dwell Modelling
"Economic and space restraints must receive due consideration. It is unrealistic to insist upon the highest service standards if the available physical space or financial resources are not sufficient to accommodate the design. A much better approach is to recognize the difficulties enforced by such restraints, and to seek alternative design solutions or operating procedures that will alleviate them. The one overriding consideration that precludes acceptance of economic or space restraints is pedestrian safety." Fruin. Pedestrian Planning and design.
Our agent analysis tools allow the user to zoom (dynamically) into the models. Clicking on the screen changes the display from agents to density, speed, space utilisation and position maps. For this model DWELL time is defined by the time between doors opening and doors closing on a platform.
The agent models show density, speeds, space utilisation and agent location. The information is stored as a file so the data can be displayed in 3D CAD tools (such as 3D Studio Max). The displays below are selected by the user - user can alter numbers on/off and standing along with behavioural choices.
Position Display (train section)
Speed Display (train section)
Density Display (train section)
Spatial Utilisation (train section)
Below - levels of service keyed to the agent locations - users can observe the dynamics of crowd density during the simulation
This modelling tool is provided with validation from field data.
