Problems solved by technology

[0005] Through sorting out and studying the research results at home and abroad, it is found that the current research focuses on the development of traffic congestion evaluation indicators, the quantification of the impact of congestion on vehicle emissions, and the relationship between vehicle speed and vehicle emissions. Quantitative research on the relationship between motor vehicle emissions. Although some studies start with the urban road network, there is no research on the relationship between traffic congestion evaluation indicators and the intensity of road network motor vehicle fuel consumption emissions.
In order to overcome the gaps in the existing research, the present invention provides a method for calculating the fuel consumption and emission intensity of motor vehicles based on the evaluation index of traffic congestion

Embodiment Construction

[0128] A method for calculating the fuel consumption and emission intensity of motor vehicles based on traffic congestion evaluation indicators, the method comprising the following steps:

[0129] Step 1. Data collection and processing;

[0130] Step two, data cluster analysis;

[0131] Step 3, build a model;

[0132] Wherein, the first step is to analyze the characteristics of the speed distribution of the urban traffic operation index, specifically including data collection, data quality control and processing, preliminary data analysis and uncertainty analysis of the speed distribution of the traffic index;

[0133] The second step is to carry out the cluster analysis of the speed distribution of the urban traffic operation index, specifically including the analysis of influencing factors, using the K-Means clustering method combined with the optimal clustering number function based on the Silhouette measure to obtain a clustering scheme, and design The clustering evaluat...

Description

technical field [0001] The invention belongs to the technical field of road network congestion and vehicle emissions, and in particular relates to a method for measuring and calculating the fuel consumption emission intensity of motor vehicles based on traffic congestion evaluation indicators. Background technique [0002] In recent years, with the development of science and technology, relying on intelligent traffic information collection technology, real-time evaluation of road traffic operation status has become a popular research direction. It is conducive to comprehensively grasping the traffic operation status, and reasonably guiding traffic participants to understand the traffic operation status objectively and correctly. Traffic management departments and research institutions at home and abroad have carried out a lot of research on traffic congestion evaluation. Combined with actual characteristics, each city has also given its definition of traffic congestion evalu...
