With 150 “urban” sensors over the urban grid of Zaragoza, 90% of all urban routes are monitored and 30% of all traffic is audited daily. The information on travel times goes directly to the Traffic Management Centre (TMC) of Zaragoza City Council and it is displayed on a web interface specially intended for management purposes. The analysis of the data collected by the Bitcarrier sensors improves understanding of the complexity of roads, neighborhoods and events so that local authorities can now intervene in traffic flow by diverting traffic to secondary arteries, adjusting phase positions and signal lights timing at road crossings and by sending patrol officers to control and manage the situation. Besides the travel time information, Citysolver is offering daily information in real time of the origin-destination matrixes in the city of Zaragoza, which is very useful for the urban planning policies. Moreover the Zaragoza City Council also publishes the information on a public website so that citizens may check the information and plan their urban trips accordingly. The information is also available for smartphones thanks to the mobile application developed by the company Agora Networks. Therefore, now the citizens of Zaragoza know the travel time to their destinations, they are able to take the least congested way to reach a destination and they can choose whether to travel by car or to take another means of transportation.
