Problems solved by technology

However, the shortcoming of these methods is that it is necessary to obtain the instantaneous speed and acceleration of the vehicle. The acquisition of these instantaneous data is difficult and takes a lot of time. Therefore, these studies cannot be directly applied to evaluate a relatively macroscopic area (traffic area, city, etc.) ) CO emissions

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, a method for evaluating the influence of road traffic characteristics on carbon monoxide emission concentration disclosed in the embodiment of the present invention comprises the following steps:

[0028] Step 1) Obtain the traffic analysis zone (TAZ) information in the research area: select the most commonly used traffic analysis unit—traffic analysis zone (TAZ) as the research object, obtain the vector map file (shapefile) corresponding to the traffic analysis zone, use ArcGIS software can obtain the basic attributes of each traffic analysis area, such as visualizing the specific location of each traffic area in the entire research area, calculating the area of ​​the traffic area, etc.;

[0029] Step 2) Obtain variables such as population economy, employment, traffic conditions and road network characterist...

Abstract

The invention discloses a method for evaluating the influence of road traffic characteristics on the emission concentration of carbon monoxide. The method includes the steps of obtaining traffic analysis zone information of a research area; obtaining population economics, employment, traffic conditions and road network characteristic variables of a traffic zone; obtaining annual average CO concentration in each air monitoring station in the research area; obtaining CO concentration data of each traffic zones by using a spatial interpolation method; obtaining other main CO emission source dataexcept for traffic in the research area; matching each variable and CO concentration data to each traffic zone; screening the variables by variable correlation analysis; establishing a geographicallyweighted regression model; and evaluating the effect of the remaining explanatory variables on the CO concentration in the model based on a final predictive model. The method of the invention analyzesthe influence of population economics, employment, traffic and road network conditions on CO emissions in units of traffic zones, and provides a theoretical basis for incorporating environmental factors into urban and traffic planning.

Description

technical field [0001] The invention relates to a method for evaluating the influence of road traffic characteristics on carbon monoxide emission concentration, and belongs to the technical field of urban traffic sustainable development planning. Background technique [0002] With the rapid development of economy and urbanization, the number and utilization rate of vehicles are increasing rapidly. According to the 2017 annual report on the prevention and control of motor vehicle pollution issued by the Ministry of Environmental Protection of China, my country has become the world's largest motor vehicle production and sales country for eight consecutive years. , Motor vehicle exhaust pollution has become an important source of air pollution in my country, especially carbon monoxide (CO). In 2016, the CO emissions from motor vehicles were 34.193 million tons, accounting for 76% of the total emissions from motor vehicles. The main gas, its massive discharge will undoubtedly pose...
