Research On Passenger Flow Attraction Of Urban Rail Transit Station

City rail transit passenger flow attraction as the planning and construction of city rail transit station and the surrounding facilities on the basis of a forecast for city rail transit passenger station layout and reasonable planning of urban rail network to provide reference.Taking into account most of the existing empirical values to determine the scope of the rail station passenger flow,not only affect the feasibility of rail transit construction decisions,but also affect the completion of the rail transportation related matters.Therefore,this paper further analyzes the impact factors of the rail transit station passenger flow attraction,and establishes the relevant theoretical model to determine the exact value of the passenger attraction range.First of all,this paper expounds the concept and characteristics of rail transit passenger flow attraction range,and through the analysis of the factors attracting influence scope of rail transit passenger flow,the city rail transit passenger flow attraction range is divided into direct and indirect site site attract attract range.Secondly,combined with the existing site classification method,the establishment of a new site classification system and analysis of the characteristics of various sites.The cluster analysis method of site classification is proposed,and 7 clusters of Dalian Metro Line 5 are selected to be divided into six categories by selecting the cluster variables.Consider walking distance of rail transit station to pedestrian time is mainly affected by personal attributes(including age,occupation,income,whether has the car)and so on,so the measured traveler usually walks to reach the rail station on time,to establish a direct rail transit site attracting scope model based on the aggregation effect,according to travelers in various sites the walking speed,walking distance to calculate the site to attract.When the travel distance,pedestrians will generally choose the minimum generalized cost or utility of transportation,this paper selects the conventional bus and rail transportation of the two competing traffic as the research object,based on the accessibility theory,the establishment of rail transit station generalized cost model based on indirect attracting scope.Finally,select the Dalian Metro Line 5 as an example to carry on the research analysis,using the above model has been built,respectively for Dalian Metro Line 5 stations and transit passenger walking attracting area attracting scope.
