Problems solved by technology

Although the detection of single-vehicle emissions is relatively mature, it is not suitable for the detection of motor vehicle emissions in the region, and the calculation of regional emissions needs to master the real-time road characteristics. At the same time, establish a set of technical methods from traffic exhaust information collection to analysis. In order to obtain data closer to the actual situation

Embodiment

[0031] The motor vehicle emission measurement method based on real-time road traffic characteristics includes the following steps:

[0032]S1: Establish the vehicle model mapping relationship according to the model classification and preset model classification standards in the COPERT model; the models in the COPERT model are mainly divided into passenger cars, light duty vehicles, buses, heavy duty trucks and motorcycles, that is, small passenger cars, light duty vehicles Cargo, heavy passenger, heavy cargo and motorcycles. The preset vehicle classification standards (that is, the models of my country's vehicle management bureau) can be roughly divided into light passenger cars, light trucks, medium passenger cars, medium trucks, heavy passenger cars, heavy trucks, motorcycles, and can be divided into gasoline vehicles and diesel vehicles according to fuel conditions. . Correspond the COPERT model with the model classification of the preset model classification standard to co...

Abstract

The invention discloses a real-time road traffic characteristic based motor vehicle emission measuring and calculating method. The method includes steps as follows: establishing vehicle type mapping relation according to vehicle type and preset vehicle type standards in the COPERT model; confirming the basic data including the traffic flow, the overall speed, the motor vehicle technical index database, the atmosphere parameter values, the road length, the motor vehicle inventory, the oil product information, the single traveling trip distance and the single traveling mean time; outputting all basic data obtained in step S2 into the COPERT model, and calculating to obtain the basic emission factor; according to the basic emission factor and the motor vehicle inventory of all vehicle types in the step S3, calculating to obtain the comprehensive emission factor of all vehicle types; according to the comprehensive emission factor of all vehicle types in the step S4, calculating the road source intensity; and further, according to the road source intensity obtained in the step S5 and the road length in the step S2, calculating the emission.

Description

technical field [0001] The invention belongs to the field of environmental science and intelligent transportation technology, in particular to a motor vehicle emission measurement method based on real-time road traffic characteristics Background technique [0002] In recent years, with the acceleration of urbanization and industrialization, the number of motor vehicles in my country has continued to grow. Compared with the 1980s, it has increased by 24 times. 1 / 3 to 1 / 2 or even higher, the NOx and O3 concentrations that represent the characteristics of motor vehicle pollution are seriously exceeded, and the air pollution in 400 of the 661 cities in my country will change from soot to motor vehicle exhaust pollution. Therefore, motor vehicle exhaust pollution has become the main source of air pollution in large and medium-sized cities in my country, and is one of the main factors affecting air quality. In this context, it is of great significance to carry out research on the p...
