Transportation activities are one of the main sources of air pollution in urban areas. The number of motorized vehicles in Bandung City in 2022 has reached 2.2 million vehicles. Common compounds produced in motor vehicle exhaust gases are NOx, CO, HC, PM10, SO2, and produce greenhouse gases such as CO2, CH4, and N2O. This study aims to obtain an inventory of emissions from the transportation sector in Bandung City and to determine the contribution of each type of motorized vehicle which is a source of pollution in the transportation sector to the amount of emissions in Bandung City. This study is divided into four stages, namely secondary data collection, determination of emission factors for each type of vehicle, calculation of emission loads for all pollutant parameters from types of motorcycles, passenger cars, and heavy vehicles, and spatial analysis to see the distribution pattern of pollutant emissions with a 30 x 30 meter grid system. The vehicle volume from transportation modeling shows a volume of 5,505,376 vehicles/hour with a proportion of 89% motorcycles, 9.79% passenger cars, and 1% heavy vehicles. The higher the average speed of a vehicle, the lower the pollutants emitted. The NOx emission load from EURO IV and EURO II gasoline cars, EURO IV and EURO II diesel cars, EURO IV and EURO II heavy vehicles, and EURO III and EURO II motorcycles are respectively 98.10 and 490.15; 574.61 and 4,349.15; 189.82 and 3,062.41; and 2,688.33 and 4,714.84 tons/year. Meanwhile, the PM emission load from each vehicle in the same order is 2.61 and 14.81; 28.93 and 294.88; 3.18 and 111.82; 59.29 and 96.44 tons/year.
