Forecasting urban air pollution using HMM-fuzzy model

Abstract

In this paper, we introduce a Computational Intelligence (CI)-based method to model an hourly air pollution forecasting system that can forecast concentrations of airborne pollutant variables. We have used a hybrid approach of Hidden Markov Model (HMM) with fuzzy logic (HMM-fuzzy) to model hourly air pollution at a location related to its traffic volume and meteorological variable. The forecasting performance of this hybrid model is compared with other common tool based on Artificial Neural Network (ANN) and other fuzzy tool where rules are extracted using subtractive clustering. This research demonstrates that the HMM-fuzzy approach is effectively able to model an hourly air pollution forecasting system. © 2008 Springer-Verlag Berlin Heidelberg.
