微观交通仿真与GIS数据共享的本体方法

Ontology Driven Data Sharing Between Microscopic Traffic Simulation and GIS

针对微观交通仿真与GIS数据共享存在的数据冗余和低效的问题,基于本体理论,提出微观交通仿真与GIS数据共享框架,给出数据共享框架的分层设计.对微观交通仿真数据特征进行概括和抽象,研究并设计微观交通仿真本体.提出基于迭代思想的微观交通仿真本体(MTSON)构建方法,重点阐述微观交通仿真本体的需求获取、分析、设计与实现过程.最后以OWL为形式化描述语言,对获取的微观交通仿真本体进行表达,为微观交通仿真与GIS数据共享的平滑实现奠定了基础.

Ontologies are put forward to resolve the problem of information integration and heterogeneous knowledge sharing.For the issue of data redundancy and inefficient sharing,a data sharing framework of microscopic traffic simulation and GIS based on ontology driven is proposed in this paper.Microscopic traffic simulation ontology （MTSON） building process of requirement,analysis,design and implementation are presented in the paper based on iterative.Ontology Web Language is used for the formal description of MTSON.The validation of MTSON and the mapping from MTSON to XML schema are also discussed.
