Integrating Air Quality Into Urban Navigation

Processes, devices, and systems for routing a user from a current location to a destination are described. A process may include determining, by a user device, a current user location (“CUL”); obtaining a current user location air quality environment (“CULAQE”); obtaining a current user location air quality index (“CULAQI”); determining a destination location (“DL”); determining a current route segment (“CRS”) from the CUL to the DL; and optimizing the CRS based on the CULAQI. A mapping application may identify the CULAQE and the CULAQI may be determined from an air quality rating. Operations may include receiving real-time air quality index data (“RAQI”) for the CULAQE, optimizing the CRS based on the RAQI, obtaining a destination location first air quality environment (“DLAQE(1)”), obtaining a destination location first air quality index (“DLAQI(1)”), receiving RAQI for the DLAQE(1), and optimizing a user's routing based on the RAQI for the DLAQE(1).
