A geographic file was prepared with the road network of Bogotá city, categorized by main roads and secondary roads, the number of lanes for each type of road and its use. The flows per lane were estimated for each of vehicle counts of 2018. Flows per lane was extrapolated for each of the roads using the kriging geoprocessing. Combustion Emission Factors were estimated with MOVES or measured directly. PM resuspended dust emission factors from the roads were estimated with equations of AP42 method where sediment loads, and silt contents were estimated as a function of grass/dense vegetation and bare ground coverages from LANDSAT8. As results, emissions for each segment road were estimated for year 2018; total emissions estimated for on-road mobile sources were: 7.4 kt PM2.5, 50.6 kt PM10, 102.7 kt NOX, 2.0 kt SO2, and 451.6 kt CO.
