Research On Slow Traffic Evaluation Index System Of Urban Rail Transit Center Station Adjacent Area

After entering the 21^st century,China's urbanization development rate is gradually slowing down.The internal structure of large,medium and small cities,as well as the traffic system are gradually taking shape.Various modes of transportation have been developed rapidly.In this situation,The optimization and development of the city's existing transportation system has gradually become the mainstream of research.As an important part of the transportation system,the rail transit system played an important role in the construction of urban traffic operations in China,and has undertaken a large number of travels in the daily life of residents.The characteristics of rail transit determine that it mainly serves for long distance travel.Because of the difficulty in solving the problem of the last kilometer travel problem.So it's necessary to coordinate the rail transit with the urban transportation system,and fill the gap by means of the end-trip-mode.As an important part of the rail transit connection method,slow traffic is the main way to realize the door-to-door travel of rail transit,and it is also the best choice to solve the convergence problem.This paper takes the optimization of urban rail transit and slow-traffic system as the starting point,and takes the evaluation of the slow system around the station as the research perspective.In order to build a set of indicators for the evaluation of slow-traffic systems,this paper builds a three-level system based on objectives,criteria and indicators.Thirty typical central rail transit stations in China are selected and classified according to the land use,they are divided into three categories:business function dominant type,public service function dominant type and community residential function dominant type.From these,we select the stations with commercial and commercial functions as the leading role which are more mature,well-equipped and well-developed in slow-traffic system,for case study and comparative analysis.In order to solve the problem of being short of quantitative research on the data of control indicators as well as the research on typical structure of road networks in the current slow-moving evaluation study,this paper analyses the different stations,and explores the road network mode which is suitable for the coordinated development of rail transit and slow-traffic system.Correlation analysis and regression analysis are carried out for the slow-traffic indicators to obtain the indicator data of optimal control,in order to provide a quantitative reference for the subsequent planning and construction process and make up the deficiency of the current research.This paper compares the results of analysis with the data of the current stations,and puts forward some suggestions for optimization.Faced with the problems arising from the implantation of rail transit into urban space,comprehensive multi-modality,multi-angle and multi-technology is an important way to solve the traffic development problems in the future.This paper is based on the previous research experience,and explores the combination of new content,new model and new method.The integration of rail transit and slow traffic is the epitome of the demand of urban traffic development.It is hoped that the perspective and content of this study can provide inspiration for urban renewal and transportation development.
