Abstract
This work presents the “City Dynamics and Smart Environment” activities of the Smart Ring project, a model for the smart city, based on the integration of sustainable urban transport services and environmental monitoring over a 4–5-km circular path, the “Smart Ring”, around the historical center of l’Aquila (Italy). We describe our pilot experience performed during an experimental on-demand public service electric bus, “SmartBus”, which was equipped with a multi-parametric air quality low-cost gas electrochemical sensor platform, “NASUS IV”. For five days (28–29 August 2014 and 1–3 September 2014), the sensor platform was installed inside the SmartBus and measured air quality gas compounds (nitrogen dioxide, carbon oxide, sulfur dioxide, hydrogen sulfide) during the service. Data were collected and analyzed on the bases of an air quality index, which provided qualitative insights on the air status potentially experienced by the users. The results obtained are in agreement with the synoptic meteorological conditions, the urban background air quality reference measurements and the potential traffic flow variations. Furthermore, they indicated that the air quality status was influenced by the gas component NO 2 , followed by H 2 S, SO 2 and CO. We discuss the features of our campaign, and we highlight the potential, limitations and key factors to consider for future project designs.
Highlights
In April 2009, a series of earthquakes rated more than five on the Richter scale happened throughout central Italy

Besides the nighttime recovery, where the SmartBus was kept for battery recharging, the road segments outside the Smart Ring were characterized by a low frequency passage
Summary
In April 2009, a series of earthquakes rated more than five on the Richter scale happened throughout central Italy. The main shock, which occurred on 6 April 2009, severely damaged the city of l’Aquila and the villages nearby. Afterwards, several actions were taken to support the population, drive disaster funds to the area and to plan the city reconstruction. A collaborative agreement between ENEA, the Italian National Agency for New Technologies, Energy and Sustainable. Development, University of Rome “La Sapienza”, AMA (Agenzia Mobilità Aquilana), Assessorato alla Smart City and the l’Aquila local government was established in 2010 to help reconstruct the l’Aquila city center according to a Smart City paradigm (e.g., [1]). Chemosensors 2016, 4, 24 produced the “Smart Ring” project, which aimed at proposing a functional and energy-efficient city model along a 4–5-km circular path, the Smart Ring, around the historical center of l’Aquila [2].
