Recommending Green Routes for Pedestrians to Reduce the Exposure to Air Pollutants in Barcelona

We demonstrate our prototype that recommends green routes for pedestrians that minimize the exposure to harmful air pollutants in a city (in our case, Barcelona). Our prototype allows potential users (including public administrations concerned with the population's health) to visualize and compare the green route computed by our method with the shortest route (analogous to those computed by widely used tools such as Google Map, which disregard air quality data), quantifying the reduction in terms of exposure to air pollutants. Results on real Air Quality Index data from the Open Data BCN portal show a median NO 2 exposure reduction of-7.82%, along with only a +4.54% median increase in terms of route length.
