Abstract

The invention provides a method for preparing a traffic source emission inventory with high spatio-temporal resolution. The method includes: Step 1: Obtaining street road network composition information of the target city; Step 2: Obtaining traffic flow information of each road section of the street; Step 3: According to the traffic flow information of each road section of the street, calculating the traffic flow rate of various vehicles per hour Traffic flow of each road section; Step 4: According to the traffic flow of various vehicles in each road section per hour, calculate the pollutant emissions of vehicles with different service life. The invention considers the three factors of road network structure, motor vehicle type and traffic change status, obtains the hourly driving change of motor vehicles, compiles the motor vehicle pollutant discharge list in the area, and can prepare hourly traffic source pollution on the street scale emissions inventory.

Description

technical field [0001] The invention relates to the technical fields of geographic information and resources and the environment, and can be used for numerical simulation of air quality, prevention and control of air pollution, and refined management of air quality, and in particular relates to a method for preparing a traffic source emission list with high temporal and spatial resolution. Background technique [0002] Motor vehicle pollutant emissions are one of the main reasons that affect urban air quality. The emission inventory of traffic sources is the quantification of pollutants emitted by motor vehicles. The compilation of traffic pollutant emission inventories with high temporal and spatial resolution can finely evaluate traffic pollutant emissions. Quantify the spatio-temporal distribution of pollutant emissions from motor vehicles to achieve a refined simulation of urban air quality. [0003] From the perspective of influencing factors, the emission of pollutants...
