Traffic global analysis on the whole italian road network.

In this paper we analyze the speed profiles on the whoxle Italian road network. More precisely, using Octo Telematics GPS data (about 3% of the total Italian cars amount) collected during four weeks of May 2011, we have built up for everyday of the week a mean speed profile with a time resolution equal to 15 minutes, obtaining about one million speed profiles. For this research working we developed software able to efficiently navigate the full Italian road network designing its topological properties, and algorithms for traffic control, prevision and governance. Moreover we discovered that a strong correlation function (>90%) represents 96.4% of all data with a reduced number of profiles (256). This work was performed in order to construct an ICT (Information Communication Technology) system for monitoring and managing traffic, with a particular attention to the safety for individual passengers, vehicles and goods.
