Research On Route Scheme Optimization Of National Provincial Trunk Line Based On FAHP

The continuous development of transportation methods such as roads,railways,water transport,and civil aviation not only provides infrastructure conditions for China's economic development,but also is a leading industry in economic construction.Highway transportation,as the most dense transportation mode,plays an important role in the economic and social development of our country.Based on the relevant theoretical knowledge of highway route selection,this paper uses FAHP(Fuzzy Analytic Hierarchy Process)evaluation method to construct highway route optimization evaluation system,which provides decision-making reference for highway construction work.The specific research content is as follows:(1)Starting with the criteria for selecting roads,we will explore in detail the complexity of road selection and provide theoretical basis for the optimization of highway routes.(2)According to the characteristics of the highway project,a highway route plan optimization evaluation system is constructed in combination with the analytic hierarchy process and the fuzzy comprehensive evaluation method.That is,the weight of the indicator is determined by the AHP method on the basis of the expert's score,and then the fuzzy comprehensive evaluation method is used for the synthesis calculation to obtain the evaluation result.(3)According to the example of the optimization work of Changjiu Avenue,the FAHP method is used to select the best solution through the analysis of the economic conditions and topography of the project area.Under the guidance of theory and practice,this paper takes Changjiu Road as an example.Based on the reasonable selection of evaluation indicators and the establishment of a comprehensive evaluation system,the paper uses AHP and fuzzy comprehensive evaluation method to give a route selection and optimization program.This study is helpful to solve the unscientific problem of route selection caused by many considerations of indicators and lack of experience of designers or knowledgeof one-sidedness in highway construction practice,which will help improve the scientific rationality of China's provincial highway route optimization.This article is conducive to promoting the change and improvement of the road construction decision concept,and has practical reference significance for effectively improving the level of China's highway construction.
