Motor vehicle emission list measuring and calculating method and device based on MOVES model

Abstract

The invention discloses a motor vehicle emission list measuring and calculating method and device based on an MOVES model. The method comprises the following steps: acquiring a local basic data set; carrying out localization processing on the MOVES model according to the local basic data set, and correcting basic emission factors in the MOVES model to obtain corrected motor vehicle emission factors, so as to establish a multi-dimensional motor vehicle emission factor database; acquiring activity level data of different geographic areas in different time periods so as to obtain a traffic information database, and acquiring meteorological data of different geographic areas in different time periods; and according to the multi-dimensional motor vehicle emission factor database, the traffic information database and the meteorological data, measuring and calculating the motor vehicle emission amount in real time by using a multi-dimensional motor vehicle emission measurement and calculation method. According to the method and the device, a more accurate high-resolution motor vehicle emission list can be established, and the influence of factors and conditions such as different speeds and different weather under different time and space on motor vehicle emission can be dealt with.

Description

technical field [0001] The present invention relates to a technology for compiling a pollutant discharge inventory, and more specifically, the present invention relates to a motor vehicle emission inventory calculation method and device based on a Motor Vehicle Emission Simulator (MOVES, Motor Vehicle Emission Simulator) model. Background technique [0002] With the rapid growth of the number of motor vehicles, the emission of motor vehicle pollutants continues to rise. Motor vehicle pollution has become the main source of pollution in most areas of my country, and the share of pollution emissions shows a clear upward trend. The motor vehicle emission inventory is a collection of information on various pollutants emitted by motor vehicle pollution sources, and is an important reference for the government and environmental protection departments in policy formulation and environmental management. [0003] In 2001, the U.S. Environmental Protection Agency (EPA) developed a com...
