This　paper　studies　the　multiple　events　character　of　pedestrian　platoon　with　the　technique　of　video　analysis.　Meanwhile,　applying　K-means　cluster,　we　select　three　criterions　which　are　the　average　speed,　the　width　and　the　length　of　pedestrian　platoon,　the　crossing　process　was　divided　into　multiple　events　at　signalized　intersections.　The　application　of　cluster　analysis　in　the　division　of　multiple　events　was　proved　through　case　study,　and　it　reflected　the　phased　characteristics　of　pedestrian　platoon.
