Study On The Configuration And Layout Of The Connecting Facilities Outside The Urban Rail Transit Station

With the rapid development of socio-economic,urban traffic congestion,environmental pollution and other problems are becoming increasingly serious.Vigorously develop urban rail transit,which has the advantages of large traffic volume,fast speed,high punctuality,good safety,less pollution,less occupation of road resources and other advantages,has gradually become an important way for large and medium-sized cities to alleviate urban traffic congestion,reduce road traffic pressure and improve the quality of urban trasport services.However,due to the high construction cost,long construction period and limited by engineering feasibility,urban rail transit network density and station coverage cannot reach the level of conventional public transit,and the accessibility is relatively low.Therefore,the full play of the urban rail transit system transportation potential relays on the effective connection with other modes of transportation.As the only entrance for passengers to enter the urban rail transit system,the rail transit station is an important place for passengers to transfer between urban rail transit and other modes of transportation.All transfer behaviors are ultimately realized through various connecting facilities around the urban rail transit station.The reasonable configuration and layout of various connecting facilities is the key to ensure the safe,convenient and efficient transfer for travelers.Therefore,it is of great significance to study the configuration and layout of connecting facilities outside the urban rail transit station.Firstly,the paper introduces the concept,function and classification methods of urban rail transit station,analyzes the composition of urban rail transit access modes and the characteristics of different access modes,and puts forward the goal and principle of connecting facilities configuration of urban rail transit station.Secondly,on the basis of combing the connecting passenger flow prediction process of urban rail transit station,the prediction methods of connecting passenger flow in different directions and modes of urban rail transit station are studied.This paper establishes the prediction model of proportation of passenger flow at different entrances and exits of station based on land use and the prediction model of different access modes sharing rate based on Logit model.Thirdly,the paper summarizes the composition of urban rail transit station connecting facilities,analyzes the configuration requirements of connecting facilities of various types of stations and the overall spatial layout principles of connecting facilities,and focus on the key points of facilities layout and the scale calculation methods of corresponding facilities of five access modes of walking,bicycle,bus,taxi and car.Then,this paper constructs the evaluation index system of connecting facilities configuration and layout scheme of urban rail transit station.On the basis of analyzing and summarizing the existing comprehensive evaluation methods,this paper establishes the evaluation model of connection scheme based on matter element theory.At the end,this paper takes the Chengdu Metro Line 13 first-stage project as a case study.The analysis results verify the operability and practical value of the configuration and layout method system of urban rail transit station connecting facilities proposed in this paper.
