Crowd Rule
Introduction
The Crowd Rule uses the density check to look for the specified density of tracks within the selected area with the given time period.
The density value will vary depending on the size of an area. Typically the density values are very small (i.e. less than 1) unless the area being used is very small or the number of tracks expected is very high. If you are finding the density check difficult to configure due to the size of the area then consider using the count check instead.
