摘　　要：通过对出租车GPS数据进行预处理、地图匹配、运营信息挖掘,可以获得与出租车运营有关的信息,单次行驶的时间、距离、经过的路径等。从浮动车数据钟挖掘出租车运营信息,获得出租车在城市运营中的平均运营速度、平均运营时间、平均出行距离等信息,并在结合城市出租车需求的基础上,给出了确定出租车合理规模的方法。同时以广州的出租车数据为基础,对该方法进行了验证。结果表明该方法能够更准确地为出租车提供合理规模,为出租车管理及交通规划等提供科学依据。After data preprocessing,map matching and data operations mining for floating car data of taxi,the taxi operation information could be obtained,such as single travel time,distance and paths.A method to conform taxi reasonable scale is put forward combining the unban taxi need with urban taxi actual operating information such as the average operating speed,the average operating time,average trip distance,which are excavated from the floating car data.Based on the Guangzhou taxi GPS data,the method has been verified.The result shows that the method can be used to calculate the urban taxi reasonable scale accurately,as well as to provide the scientific basic for taxi management and traffic planning.
