So far, the data was available for internal use only. Now everyone can get free access by using google maps. The service has been working since 15 December. By clicking on “traffic” the map of the city will be red, yellow or green coloured, according to the traffic situation of the different areas (hoping to have the more roads green!).Bologna is one of the first Italian cities to adopt this service, which was available only to the world’s largest cities. This service marks an important step forward towards a larger diffusion of information concerning the traffic.
