Evaluación Del Impacto De Las Fuentes Móviles Sobre La Calidad Del Aire Y Sus Externalidades En La Ciudad De Tunja

Abstract

This document presents the work carried out in the framework of the internship at the Secretariat of Mobility and Territorial Life of the city of Tunja, where support was provided in the formulation of the thematic axis of environmental management of the Mobility Observatory. During the internship, several activities were carried out focused on the analysis of air quality in the city. For this purpose, data from monitoring stations was processed and analyzed, as well as the elaboration of pollutant dispersion maps using spatial modeling tools. In addition, the methodology for calculating the environmental externalities generated by the vehicle fleet was determined, establishing a formula to quantify the costs associated with vehicle pollution in terms of public health and environmental impacts.

As part of the process, a detailed study was also carried out of the regulations in force, both nationally and internationally, related to air quality and its link with mobile sources. This made it possible to compare the regulations and standards applicable in Colombia with the recommendations of international organizations such as the World Health Organization (WHO) and reference regulations in other countries. This process provided fundamental technical and analytical inputs for the development of the Mobility Observatory, facilitating the integration of environmental criteria in urban transportation planning and contributing to the generation of key information for decision-making on sustainable mobility and air quality in the city of Tunja.
