Nowadays, as urban populations grow, noise pollution is significantly affecting residents’ quality of life. Studies for Bogota, Colombia suggest that the main source of noise is road traffic. Bogota’s situation is likely to worsen as the total volume of vehicles increases at around 10% per annum. Although strong legislation has been approved to address noise pollution, limited understanding exists of where these limits are exceeded. Using Geographic Information Systems, a noise map for Bogota was developed. It presents theoretical noise levels based on experimental calculations of sound pressure and traffic flows across the road network calculated with a four-step transport model. Results showed that legal limits are extensively exceeded in Bogota. This analysis highlights areas that are most likely to exceed noise pollution standards, indicating areas where noise monitoring should be implemented. Field-based measurements are needed to confirm and refine the results of the modeling.
