Research On Post-use Evaluation Of Urban Rail Transit Station In Karst Mountain Area

The topography Because of the special topography,the land using of karst mountain is very tight,and the transportation resources are also limited.However,with the development of economy and society,people’s demand for motorized travel and requirements for travel service levels are constantly increasing.In view of the lack of transportation infrastructure and the characteristics of clusters in the mountainous city of Llost,the development of rail transit is the best choice to fundamentally improve passenger transport conditions.Urban rail transit construction is an infrastructure project with large investment,extensive coverage,and strong comprehensiveness.Once completed,it will be difficult to change.Therefore,a series of work such as station planning,design,and construction must be done.This paper constructs a post-use evaluation index system for urban rail transit stations in karst mountainous regions,and takes Guiyang Rail Transit Line 1station as an example to conduct scientific evaluation research and analysis.Finally,an optimization strategy for the construction of rail transit stations in karst mountainous urban areas is proposed.The construction of rail transit stations provides theoretical and practical guidance.The main research results are as follows:(1)Karst mountain urban rail transit stations had the characteristics of complex engineering construction environment,rich station forms,and diverse station structures.Natural factors were the main influencing factors after the use of urban rail transit stations in karst mountain areas.(2)A post-use evaluation index system for karst mountain urban rail stations has been established.The criterion layer had three indicators: functional layout,visual landscape,and ecological environment.The indicator layer had a total of 16 indicators.(3)Taken Guiyang Rail Transit Line 1 station as an example,the Analytic Hierarchy Process was used to obtain the weights of the evaluation indicators for Guiyang Rail Transit Stations after using.Among them,the weighting order of the criterion-level indicators were as follows: functional layout,visual landscape,and ecological landscape.The top five indicators in the order of the weight of the indicator layer were the rationality of functional area division,the beautiful and creative decoration,the rationality of the layout of service facilities,the reflection of the local characteristics of ethnic culture,and the convenience of transferring with other public transportation in the city.The weight of mitigating the impact of urban atmospheric environmental quality and vegetation landscape abundance was relatively small.Then reused the fuzzy comprehensive evaluation method to conduct a comprehensive post-use evaluation of the Guiyang Rail Transit Line 1 station:Penshuichi station had the best evaluation after using;West Lincheng Road Station was the second place;Laowantang Station and Douguan Station were in the back.(4)Six optimization strategies for the construction of urban rail transit stations in karst mountainous areas are proposed.The first is to increase economic investment and build a comprehensive passenger transport system;the second is to plan scientifically and select locations effectively to improve the travel structure;The third is to expand business integration and promote each other to create a "win-win";the fourth is to optimize the streamline organization to ensure fast and efficient travel;The fifth is to grasp the creation of the environment and highlight the unique local temperament;the sixth is to improve the management system to ensure safe and civilized use.
