轨道交通站点公共自行车租赁点布局研究

以轨道交通站点为中心，提出分层分级布设公共自行车租赁点的布局方法。根据用地性质、居住人口和各层自行车方式分担率，将公共自行车租赁点划分为中央节点、一级网点和二级网点，进而确定各级公共自行车租赁点规模和公共自行车数量，随后基于免疫优化算法选取合适的二级网点作为公共自行车管理点。最后以南京市一号线南沿线天印大道站为例，给出其辐射范围内的公共自行车租赁点布局方案。

Research on the Layout of Bike Rental Stations around a Railway Station

This paper constructs a hierarchical structure of bike rental stations around a railway station. Based on land use function, population and bike mode split rate of every layer, bike rental stations are divided into three parts, namely nuclear node, one-level nodes and two-level nodes, and later the quantity of bike rental stations and bikes are estimated. Then an improved immune algorithm is utilized to select several appropriate two-level nodes as bike management nodes. Finally, a case study of Nanjing Tianyin Road Station is conducted, and the paper gives the layout proposal of bike rental stations within the radiation scope of the railway station.
