面向出租车轨迹的数据库管理系统设计与应用

Design and Application of Database Management System for Taxitrajectory data

文中就南通出租车的轨迹数据管理问题,针对轨迹数据量大且不断累积的特点,基于Arc Engine和SQL设计了轨迹数据库管理系统,该系统实现了轨迹数据的空间和属性查询、车辆的空间分布分析以及空驶率的计算等功能,并以空驶率为例,详细阐述了该系统的设计与功能,从而说明该系统可使数据管理和分析工作变得更为便捷。

This paper focuses thetrajectory data management of nantong taxis.the trajectory database management system is designed on the basis of Arc Engineand SQL for the characteristics of large and cumulative trajectory data.The system realizes the functions of spatial and attribute query of trajectory data,spatial distribution analysis of vehicles,and calculation of empty-loaded rate.taking empty-loaded rate as an example,the design and function of the system are described in detail,which shows that the system can make data management and analysis more convenient.
