| The new Shuangliu regional transportation is more convenient.The existing transportation system is a three-dimensional system integrating water,land and air.Overall,it has a higher regional road network density,but the transportation links between townships are weaker than the regional transportation links.The construction of the Yongan South-Huanglongxi hanging monorail transportation demonstration line can greatly increase the transportation needs of Yongan,Biological City,Huanglongxi and village gathering areas along the line,and can alleviate the road traffic pressure and promote regional transportation development.At the same time,it can improve the basic transportation facilities of Huanglong River,alleviate the current situation of traffic congestion in scenic spots,improve the quality of scenic spots,and drive the development of scenic spots.The study of the line plan has a crucial impact on the development of the city and the planning of the line network,and plays a decisive role in the safety,economy and convenience of the line.Unreasonable wiring schemes may lead to project abandonment and cause huge damage to the economy and the environment.China’s suspended monorail transportation is still in the experimental stage.At present,domestic scholars mainly focus on suspended monorail transportation vehicles and track beams,and have little research on line design.Currently,there is no complete set of line evaluation models suitable for suspended monorail lines Program evaluation.Therefore,it is necessary to start research on the scheme of suspended monorail traffic lines.This article mainly completed the following aspects:(1)Based on the research results of scholars at home and abroad,the technical characteristics and applicable scope of suspended monorail transportation are expounded.According to the special functional positioning and structural form of the suspended monorail,the design method of the plane and the longitudinal plane of the suspended monorail and the factors to be considered in the design of the route are analyzed.(2)From the five aspects of technology,economy,tourism,environment,and society,the main influencing factors of the route plan were studied.Using survey analysis and target decomposition,a comprehensive evaluation index system consisting of 5 criterion levels and19 evaluation indexes was established.The law assigns weights to each criterion layer and each index within the criterion layer.(3)The characteristics of commonly used line scheme evaluation methods are analyzed.Considering that the factors affecting the suspension monorail line scheme have quantitative and qualitative characteristics,a decision model combining fuzzy comprehensive evaluation method and gray correlation coefficient method is established.(4)Based on the scheme design of the Yongan South-Huanglongxi suspension monorail transportation line,the grey correlation analysis method is used to analyze the quantitative indicators,the fuzzy comprehensive evaluation method is used to analyze the qualitative indicators,and then the second-level fuzzy synthesis is performed according to the structure of the indicator system Evaluation,the ranking of the pros and cons of the program is obtained,which verifies the rationality of the program and the effectiveness of the evaluation model.In this paper,the evaluation index system and gray comprehensive evaluation model developed by the research institute on the optimization of the Yongan South-Huanglongxi suspended monorail transportation line plan are scientific and practical,which is very important for the design of the domestic suspended monorail transportation route selection.Theoretical and practical significance. |
