In dense urban areas, public space is an important resource that often a source of conflict between different users. In recent years, the Municipality of Bologna has deployed a mobility strategy strongly focused on the use of intelligent transport systems (ITS) for traffic regulation and enforcement. These are considered fundamental for an effective implementation of mobility policies. A new platform has been introduced to collect, integrate and elaborate data coming from ITS infrastructure in the city, transmitting information in real time on the traffic situation to citizens. Such systems have also been used at traffic lights to control the abuse of red light crossings, with a dramatic reduction of accidents and injured people. Another useful application of this technology has been to reduce instances of double parking of vehicles, especially in the arterial roads fundamental for the public transport.
