In view of the tide problem of fast developed city public bike system,this paper proposes a station clustering algorithm based on SimRank,which uses the characteristics of public bike.Firstly,the definition of station similarity is proposed based on the relation between stations.Secondly,the SimRank algorithm is introduced to calculate the similarity between stations.Finally,according to the calculated similarity values,the stations are clustered with the idea of maximum similarity priority.Experimental results show that the clustering results by the proposed algorithm have accurate bike flow characteristic and regional characteristic,meanwhile,the members in same cluster have great relevance.
