The invention discloses a shared bicycle parking area layout method based on a clustering algorithm. The method comprises the following steps: S1, acquiring historical position data of shared bicycles; S2, performing coordinate conversion on the position data of the shared bicycle; S3, initializing a DBSCAN algorithm clustering parameter and carrying out preliminary clustering; S4, adopting a k-means clustering algorithm to divide overlarge classes; S5, performing evaluation index calculation and clustering parameter traversal condition inspection; S6, proposing an optimal shared bicycle parking area position and capacity; and S7, judging the stability of the layout effect of the parking area. According to the method, the situation of unreasonable parking area planning of the shared bicycles can be effectively relieved, the parking areas are arranged in a more targeted mode, the standardized management level of the shared bicycles is improved to a certain extent, parking area planningis conducted by considering the factors such as position information of different time periods and the service radius of the shared bicycle parking areas. Parking requirements and walking distances ofusers in all time periods can be planned as a whole.

    一种基于聚类算法的共享单车停车区布设方法,包括以下步骤:S1、获取共享单车历史位置数据;S2、对共享单车位置数据进行坐标转换;S3、初始化DBSCAN算法聚类参数并初步聚类;S4、采用k均值聚类算法划分过大类;S5、评价指标计算与聚类参数遍历情况检验;S6、提出最优共享单车停车区位置及容量;S7、判别停车区布设效果的稳定性。本发明方法可以有效缓解共享单车停车区施划不合理的情况,更有针对性的布设停车区,一定程度上提高了共享单车的规范化管理水平,并且本发明方法兼顾不同时段的位置信息、共享单车停车区的服务半径等因素进行停车区施划,可以统筹全时段的停车需求与使用者步行距离。
