出租车GPS数据的应用研究

Research on the appliction of taxi GPS data

出租车运行轨迹遍布城市整个路网,装载GPS的出租车不但能够提供系统本身的运营信息,也能提供有关路网状态的信息。从交通信息处理与数据挖掘的角度出发,对出租车GPS数据在交通状态估计、交通行为分析、出行OD预测、出租车运营管理等诸多方面的应用进行系统的综述。最后针对出租车和路网两方面应用上存在的不足指出有利于拓展出租车GPS数据应用的参考性建议。

The travel trajectories of taxi are all around the whole network. Taxi equipped with GPS can provide not only operational information of taxi system but also estimated information of network state. From the perspective of traffic information processing and data mining, it systematically proposes the research on the applications of taxi GPS data in the traffic state estimation, traffic behavior analysis, origin-destination forecasting and taxi＇s operational management. Finally, the suggestions are given to help extend the further applications of GPS data in terms of taxi and network.
