Air quality model validation in urban area: a new approach using a wireless pervasive sensor system.

TL;DRAbstract

This paper describes the implementation in Palermo of a new approach developed at Newcastle University (UK), in the context of the MESSAGE project (Mobile Environmental Sensing System Across Grid Environments), using a novel inexpensive pervasive sensor system. The new system infrastructure shows how additional data from the new environmental sensors, namely “mote” can improve the assessment of the impact of traffic and congestion on air quality. After an evaluation and validation process of the sensors against the precision system (City Council Environmental Cabin) the sensors where deployed in Palermo and using the data, actual traffic flows and pedestrian traffic light information (all synchronised at one minute resolution), a simulation model was set up to predict air quality, and potentially noise and exposure levels for pedestrian. The proposed approach has been evaluated using a case study area in Palermo, namely a street canyon, in Libertà Avenue. Analysis, calibration and val
