In places of public assembly it is important to differentiate how spaces are used. We define two fundamental types - static and dynamic. Static spaces are where the crowds predominately stand/observe and dynamic spaces are areas where the crowds are typically moving.
These two types of space will have different utilisation factors, experience different densities and hence have different types of risk and crowd management requirements. For example a concert will experience higher crowd densities closest to the front of stage. Routes to and from entry/exit points, bars, concession etc. should be free of trip hazards. These different spaces should be differentiated in the site plan so that operators know where the crowds are moving and where crowds are predominately standing/static.
Standing crowd densities are illustrate via the links below.

Some hisotorical images of crowds

Bern’s Wankdorf Stadium ahead of the 1954 World Cup. Historical crowd density estimator. 6 people per square metre. Long before the European standards and the Green Guide. Amazing image.
