The　urban　floating　car　data　(FCD)　collection　system　is　usually　constructed　on　the　basis　of　the　taxi　dispatch　system,　and　the　taxies　are　serviced　as　the　floating　cars.　Thus,　the　floating　car　data　(FCD)　collected　from　the　system　also　include　the　operation　information　and　status　information　of　taxies.　This　paper　proposes　several　Floating　Car　Data　based　indexes　and　analysis　models　for　taxi　operation.　Taking　Beijing　as　a　case　for　study,　the　paper　analyzes　the　parameters　including　travel　mileage,　virtual　mileage　ratio,　time-space　distribution　on　the　road-network　and　the　labor　intensity　of　drivers.　Then,　several　important　parameters　about　the　taxi　operation　in　Beijing　are　concluded　in　this　research.　These　data　can　provide　useful　data　support　for　the　taxi　dispatching　management,　taxi　stop　planning,　vehicles　deployment　and　general　decision　making　for　the　management　of　taxi　industry.
