Barcelona has been developed as a smart city during last years. Travessera de dalt is an important edge of the city which combines Vila de Gracia to Parc Guell which is the most important tourist attractive place. Therefore,redefining this edge as a smart street became an important issue. By using info-Cloud, ground projection with different colors and sizes according to the density and activities that are changing during the day is proposed for improving the pedestrian infrastructure in this highly vehicle based street.
