We developed a 3D crowd visualiser for control room applications. This allows us to both train staff to identifying density from CCTV angles and to provide control room visuals for crowd build up during an event. Each grid is 5m by 5m.
1 person per square metre
2 people per square metre
3 people per square metre
4 people per square metre
5 people per square metre - Maximum
6 people per square metre - High Risk
We use this tool to visualise complex sites - most recently for the Royal Wedding in London.
The tool was used extensively to plan the crowd numbers and density at key locations across London.
Below a series of graphics showing different crowd densities mapped against a risk scale.
From the links below you can view a 10m grid, against a tennis court backdrop, to assist in visualising crowd densities and crowd sizes. I'm going to produce a whole range of crowds against backdrops to act as both a training aid and to provide reference visuals for assessing both density and crowd numbers.
