西安地铁与共享单车接驳利用率分析和优化

Analysis and Optimization of the Utilization Rate of Connection Between Xi’an Metro and Shared Bicycles

随着城市轨道交通的发展,为解决城市轨道交通出行中站间距离过大造成的“最后一公里”问题的困扰,对西安地铁一号线“B+R”即共享单车接驳的城市轨道交通方案进行了研究。以西安地铁一号线为例,采用问卷调查法、空间句法和案例分析法相结合系统分析使用共享单车接驳城市轨道交通的用户特点、车站周围辐射区域内的共享出行特点以及出行者基本状况等因素。结果表明:共享单车使用者年龄整体趋于年轻化,骑车时间多集中于10 min之内、骑车间距多分布在1 km之内;一号线客流量对共享单车的利用率存在着数量与时变特征两方面影响;通过增加街道之间的连接、优化街道路网结构和根据实际使用情况设计街道宽度等措施提高共享单车的使用率。

With the development of urban rail transit,in order to solve the"last kilometer"problem caused by excessive distance between stations in urban rail transit,the"B+R"urban rail transit scheme of Xi’an Metro Line 1,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 systematically 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.
