1. A method for statistically tracking dynamics of a population over an area, said area comprising at least one entry point and at least one exit point, each member of said population entering said area through said at least one entry point, either exiting said area through said at least one exit point or stationing within said area, said method comprising:
a) at each entry point, providing an entry counter counting a number of members entering said area through said entry point and, at each exit point, providing an exit counter counting a number of members exiting said area through said exit point; and
b) by a processing unit,
calculating a number of members stationing within said area a plurality of times i, and
at the i-th calculation:
determining if said calculated number of members stationing within said area is higher than or equal to 0, and if said calculated number of members stationing within said area is higher than or equal to 0, calculating a next (i+1)-th calculation, and
determining if said calculated number of members stationing within said area is lower than 0, and if said calculated number of members stationing within said area is lower than 0, adjusting all values of said number of members stationing within said area previously calculated up to the i-th calculation by subtracting said calculated number of members stationing within said area at the i-th calculation therefrom; and
based on values of said entry counter and said exit counter, statistically tracking the dynamics of said population in terms of an evolution in time of said calculated number of members stationing in said area, wherein
a calculated number of members assumed to be stationing within said area at a beginning of an observation period is increased when the counted number of members exiting said area during said observation period is higher than the counted number of members entering said area during said observation period plus the number of members assumed to be stationing within said area at the beginning of said observation period.
