Embodiment Construction

[0027] The method of the invention includes: analyzing residents' travel characteristics, predicting traffic volume, determining emission factors through road experiments, calculating motor vehicle pollutant emission and performing environmental assessment.

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific examples of implementation.

[0029] 1. Analysis of travel characteristics of residents

[0030] Taking Changyi District of Jilin City as the research area, according to the division of 19 traffic districts, such as figure 2 As shown, a large number of resident travel surveys are carried out in the form of questionnaires, and the original travel data of the resident travel survey are checked and corrected, and after coding, they are entered into the database. After sorting and analyzing, the initial OD table was obtained. Then, the sample expansion method is used to determin...

Abstract

The invention discloses a method for quantizing urban motor vehicle emission load based on resident trip analysis, belonging to the technical field of intelligent traffic. The method comprises the following steps: analyzing resident trip characteristics; predicting traffic volume; determining an emission factor by means of a road experiment; calculating the emission load of motor vehicle pollutants; and evaluating environment. In the method, the practical resident trip situation information obtained by investigation is combined with a vehicle emission model, and traffic investigation data is reasonably linked with motor vehicle environment evaluation so as to calculate the motor vehicle emission load within a certain area in the urban; and by utilizing the method, necessary basic data and important parameters for total wide-zone emission load estimation of the urban traffic can be accurately and objectively provided, and practical data and decision support can be provided for controlling traffic pollution and realizing the urban traffic planning for sustainable development and the like. The method has the advantages of high accuracy and high efficiency, and is convenient to implement on the basis of fully utilizing the existing traffic investigation data.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation. Background technique [0002] The prosperity of the transportation industry brings vitality to the economic development of the city, but at the same time, the energy and environmental problems it produces also pose new challenges for urban development. Since China's economy is in a period of rapid growth, the number of motor vehicles has increased sharply, and the proportion of energy consumption of automobiles has continued to increase. China will also face more serious air pollution problems. According to the classified statistics of the sources of urban air pollutants, about 80% of the pollutants in major cities come from the exhaust emissions of traffic motor vehicles. The concept of sustainable development has penetrated into the theory and practice of urban transportation system construction. The harmonious development of urban transportation system and environment has b...
