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.
