A comprehensive evaluation method for sustainable development of urban traffic

Abstract

The invention discloses a comprehensive evaluation method for urban traffic sustainable development, which belongs to the field of urban traffic transportation system development evaluation, and comprises the following steps: (1) constructing an evaluation index system according to a TISP framework, and grading evaluation results; (2) determining a grading standard of the index according to the related national standard and the city scale; (3) calculating digital features of the cloud model by combining a multi-dimensional cloud model theory according to each index grading standard; (3) inputting digital characteristics of the cloud model, and generating a normal random number corresponding to the evaluation level by a multi-dimensional forward normal cloud generator; (4) calculating an index weight by adopting an AHP method; And (5) inputting actual measurement values of urban traffic system indexes, calculating the certainty degree belonging to each level by utilizing a comprehensivecertainty degree formula, and judging the comprehensive evaluation level according to a maximum certainty degree principle. The method is simple in step, efficient in calculation and clear in result,and has important reference significance for sustainable development evaluation of the urban transportation system.

Description

technical field [0001] The invention belongs to the field of urban traffic transportation system development evaluation, in particular to a comprehensive evaluation method for urban traffic sustainable development. Background technique [0002] At present, my country is in a period of transition from a "big transportation country" to a "powerful transportation country", and the focus of transportation construction has shifted from "scale expansion" to "efficiency improvement". In order to alleviate various problems in urban transportation, it is necessary to establish a sustainable modern transportation system, and the comprehensive assessment of urban transportation for sustainable development is an important step. [0003] There are many factors affecting the comprehensive evaluation of urban traffic, and it is difficult to establish a reasonable evaluation index system. The traditional traffic comprehensive evaluation mostly focuses on traffic congestion and accessibilit...
