x, y are average values of x, y.
Correlation coefficients were calculated (see Tables 5.8 and 5.9) for individual
years and all cities as one group. The correlation coefficients were evaluated twice
for two different road traffic intensities. The first one was average road traffic
intensity and the second one was maximum road traffic intensity defined in the
part of non-spatial data.
The correlation between the average road traffic intensity and land use areas
shows the break between the regimes at residential areas (growth after stagnation).
It is a result of new residential areas built outside of city centers and in prevailing
part without facilities. Therefore inhabitants from these areas were forced to use
