Analysis and Optimization of the Utilization Rate of Connection Between Xi'an Metro and Shared Bicycles
With the development of urban rail transit,in order to solve the"last kilometer"problem caused by excessive distance be-tween stations in urban rail transit,the"B +R"urban rail transit scheme of Xi'an Metro Line1,namely shared bicycles,was studied.Taking Xi'an Metro Line 1 as an example,questionnaire survey method,space syntax method and case analysis method are used to sys-tematically analyze the characteristics of users using shared bicycles to connect to urban rail transit,the characteristics of shared travel in the radiation area around the station,and the basic conditions of travelers.The results show that the age of shared bicycle users tends to be younger on the whole,the cycling time is mostly concentrated within 10 min,and the cycling distance is mostly distributed within 1 km.The passenger flow of Line 1 has two effects on the utilization rate of shared bicycles:quantity and time-varying characteristics.The use of shared bikes will be improved by increasing the connectivity between streets,optimizing the structure of the street network and designing street widths according to actual usage.
