基于复杂网络理论的互联网租赁自行车站的配置研究

Optimal allocation on the station of sharing bicycle-transit system based on complex network theory

为解决互联网租赁自行车乱停乱放,侵占道路的问题,处理好其与公交系统的竞争合作关系,将自行车站点配置融入公共交通规划。采用改进的可达性拓扑度量法分析评价公交系统站点可达性,进一步结合自行车接驳范围,建立自行车站点配置模型。以天津市公交系统为例进行自行车站点的合理配置。结果表明:在公交系统中合理配置互联网租赁自行车站点后,公共交通网络平均出行站点数量降低了5.83%,平均换乘系数降低了4.27%,验证了模型的可行性和合理性,提高了公交系统网络覆盖率、站点利用率以及公共交通的出行效率。

In order to deal with the confusion in parking and misplacing of the Internet rental bicycles,and to handle well the competitive-cooperative relationship with the public transportation system,the configuration of the bicycle site is integrated into the public transport planning.The improved reachability topology measure method was adopted to ana.lyze and evaluate the accessibility of the public transportation system site.Furthermore,a bicycle site allocation model was established with the the bicycle connection range.The public transport system of Tianjin was taken as an example to carry out the reasonable allocation of bicycle sites.The results showed that the average of travel site number and transfer coefficient for public transportation network decreased respectively by 5.83%and 4.27%after rational allocation of the Internet rental bicycle station in public transportation system,which verified the feasibility and rationality of the model,and improved the utilization rate of site coverage,public transportation network system and the efficiency of public trans.port.
