The use of the Systems up to now realized, both at urban and extra-urban level, allowed to evaluate in a concrete way the benefits from ITS. Data from the European Commission reveals that, in several applications realized in European Countries, reduction of travelling times of 20% were obtained as well as an higher network performance, up of 5-10%, and higher safety, up of 10-15%.

These positive results show ITS advantages, in a logic of sustainable development, to the environment, efficiency, citizens safety and to competiteveness and they confirm the ITS key role for mobility policies.
