Abstract: 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.
