We are looking at one of the busiest roundabouts in Alicante (Spain). As visible information, we can appreciate the traffic going in and out, people walking around and through, and several bars located on the periphery. As invisible information, we can find: - Patterns of traffic: they change during the day, becoming the roundabout busier at first thing in the morning and by the end of business hours. - Patterns of people walking: There are more people passing by from 18.00 to 21.00 than during the rest of the day. - Bar's attendance: The bars are not equally crowded during the day than from 20.00, time in which they reach the maximum attendance of the day. All this invisible information can help determine the functioning of the traffic lights. I mean, using all data coming from patterns, you can programme the traffic lights system so to adapt to the traffic to avoid traffic jams during rush hours, to adapt to the time of the day that more people walking by accumulates and increase the light shift frequency and avoid having pedestrians wait too long to cross. Finally, the number of people sitting in the tables outside bars might be use to increase security in that area and avoid any delinquency activity.
