pedestrianDispersionWeight [double]:
Describes dispersion depending on agents, i.e. the spatial spread of aerosol clouds caused by moving agents
(which results temporally in local air movement). Each agent that passes a cloud with speed > 0 m / s contributes
to the dispersion of the cloud: deltaRadius = pedestrianSpeed * pedestrianDispersionWeight
This increases the radius of aerosol clouds equally in all directions (three-dimensional).
