Road network traffic improvement scheme efficiency assessment method based on data envelopment analysis

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...

Problems solved by technology

The main characteristics and defects of these technologies include: (1) Based on the survey data, select road network performance evaluation indicators and methods to evaluate the overall status of road network operation and service quality. Due to differences in data collection methods, evaluation indicators, and evaluation methods, evaluation The consistency of the results has not been confirmed; (2) It mainly evaluates the current operation status and service quality of the road network. Due to the lack of prediction function, it is impossible to evaluate the pros and cons of the road network upgrade and improvement plan to be implemented; (3) Evaluation indicators The selection is mainly on the "output" indicators of road network operation, and less attention is paid to the "input" indicators of the road network, which cannot fully reflect the operational efficiency of the road network
