charging pile Siting Recommendations via the Fusion of Points of Interest and Vehicle Trajectories

China Communications 2017年第11期14卷 29-38页

作者： Yuan Kong Jianping Wu Ming Xu Kezhen Hu Department of Civil Engineering Tsinghua University Beijing 100084 China

By mining of the requirements of lots of electric vehicle users for charging piles, this paper proposes the charging pile siting algorithm via the fusion of Points of Interest and vehicle trajectories. The proposed algorithm computes appropriate charging pile locations by: 1) mining user Points of Interest from social network; 2) mining parking sites of vehicle form GPS trajectories and 3) fusing the Points of Interest and parking sites together then clustering the fusions with our improved DBSCAN algorithm, whose clustering results indicates the final appropriate charging pile locations. Experimental results show that our proposed methods are more efficient than existing methods.
