All data are batch processed, with a combination of specific tools and algorithms.
For an observer, numerical data doesn t make immediate sense without some analysis. On the other hand, it is well known that graphical representation of numerical data is much easier to absorb and is more meaningful to the human comprehension. Therefore, it makes better sense to represent the traffic volumes in Athens by means of graphics. Pie charts and bar graphs are easy to understand, but in this case, it is much more meaningful and practical to integrate the graphical representation of the traffic volume data in the actual Athenian road map. The first step is to graphically represent the Athens road network.
