Counting System and Classification of the Traffic

The Traffic Classification and Counting System, including its Automated Classifiers Vehicle (CAVs) - physically installed in the roads, for a total of 14 stations - communicates with the Control Center through the private fiber optic network, with possibility of permanent and on-line verification of the reliability of their registrations.

The permanent verification is guaranteed through the provision of an on-line data circuit.
