The　public　transport　IC　(Integrated　Circuit)　card　widespread　used　provides　a　new　data　source　for　collecting　passenger　flow　information.　The　effective　information　of　bus　traveling　can　be　obtained　from　IC　card　data　by　using　the　data　mining　technology.　The　attraction　weight　coefficient　OD　calculation　method　is　used　for　obtaining　the　basis　public　transport　passengers　flow　data.　Based　on　these,　this　paper　analysed　the　data　mined　and　discusses　its　application　according　to　the　characteristics　of　urban　public　transportation.　The　effective　information　of　passenger　flow　distribution　was　used　for　arranging　the　Public　Transport　operation　mode.　This　paper　makes　up　the　shortfall　that　IC　card　data　is　only　used　in　calculating　the　distance　but　not　in　mining　meaningful　information　about　the　arrangement　of　route　operation　mode.　Finally.　by　real　case　study　of　two　lines　of　Beijing　Public　Transport　Group,　the　feasibility　and　practicability　of　the　method　proposed　were　verified.
