Embodiment 1

[0069] Such as Figure 1-4 , technical scheme of the present invention comprises the following steps:

[0070] 1, road network operating efficiency evaluation index system construction;

[0071] 2, evaluation index quantification and acquisition;

[0072] 3, road network improves alternative selection;

[0073] 4, based on data envelopment analysis, road network is improved the alternative effectiveness sorting;

[0074] The construction of road network operation efficiency evaluation index system uses the "multiple inputs and multiple outputs" system analysis idea to evaluate the efficiency of road network improvement schemes. The specific indicators include two categories: "input" and "output", "Input" indicators represent the road network scale, road network structure, etc., and "output" indicators represent the quality and level of road network traffic operation; on the basis of considering the representativeness, objectivity and availability of indicators, construct ro...

Abstract

The invention discloses a road network traffic improvement scheme efficiency assessment method based on data envelopment analysis. Step one: an assessment index is quantified and acquired and preliminary road network improvement alternative schemes are formed; step two: the road network improvement alternative schemes are selected; that is to say, the road network improvement alternative schemes are effectively sequenced based on data envelopment analysis; and an optimal road network improvement scheme is obtained. Road network operation efficiency is assessed via adopting a "more input more output" system analysis idea by aiming at multiple schemes for road network updating. A road network operation efficiency assessment index system is established based on principles of representativeness, objectivity and availability. Besides, the assessment index is divided into an "input" type index and an "output" type index, and an assessment model of road network operation efficiency is established by applying data envelopment analysis (DEA). Calculation is performed by adopting a C2R model in the DEA method so that relative effectiveness and relative efficiency values among all the road network updating schemes are obtained and effectiveness sequencing of all the schemes is obtained.

Description

technical field [0001] The invention relates to a method for evaluating the efficiency of road network traffic improvement schemes based on data envelopment analysis, belonging to the field of urban traffic planning and management, and in particular to an evaluation method for road network improvement schemes. Background technique [0002] The road network structure in the central area of ​​the city is basically formed, the nature of the surrounding land is basically fixed, the traffic demand is large, and the traffic congestion is serious. The implementation of road network upgrades and traffic management measures or policies for this type of road network will lead to large-scale traffic congestion in the road network. distribution, therefore, there are greater difficulties and implementation risks. Researchers at home and abroad have proposed many road network improvement measures, upgrading strategies and methods. However, there is a lack of relevant theoretical support a...
