The above video is a visualisation of a simulation involving people moving through the concourse of Central Station, Sydney over the course of one hour. It depicts a scenario in which there is no threat, and which can be compared with scenarios where different types of threats are introduced.

This type of simulation, as undertaken at the University of Wollongong, can be used for the evaluation of a large range of risks and threats, including:
