摘　　要：以智能交通系统的应用为背景,研究了基于OSM(OpenStreetMap)路网数据的构造过程、路网数据的转换.重点对OSM数据的构造过程、数据的重构技术进行了探讨,以适应海量城市计算背景下路网数据独立于系统,达到实现路网数据语义标准化处理的目的.在构造的过程中,显示了路网数据构造的难度及问题,在数据的重构中尽量避开不合理的数据构建,以便更有效地实现智能城市管理所需要的基础数据的可靠性和稳定性.The construction of road-net data for Intelligent Transportation System( ITS) based on Open Street Map( OSM) are the foundation and precondition of realizing the calculation of the ITS. Against the background of the applications of ITS,the paper investigates the construction processing and conversion based on OSM road-net data. It mainly explores the construction process,reconfiguration and fusion of OSM data,which helps making the road-net data independent on the application system under the background of huge amounts of city calculations and realizing the aim of standardization in road-net data semantic. Additionally,we still study several problems that probably occur during the construction and reconfiguration process of road-net data in order to avoid unreasonable data construction and to satisfy the demands of intelligent city administration for the reliability and stability of the basic data.
