Porto city has an in-place infrastructure of fixed and moving sensors in more than 400 buses and roadside units, with both GPS and mobility sensors in moving elements, and with environmental sensors in fixed units. This infrastructure can provide valuable data that can extract information to better understand the city and, eventually, support actions to improve the city mobility, urban planning, and environment. Our system provides a full stack integration of the information into a city dashboard that displays and correlates the data generated from buses and fixed sensors, allowing different visualizations over the traffic and
environment in the city, and decisions over the current status of the city. A good example relates bus speed variation with possible anomalies on the road or traffic jams. Visualizing such information and getting alarms on anomalies can be a valuable tool to a city manager when taking urban planning decisions to improve the city mobility
