基于GIS的交通事故多维分析系统的研究

Study of Multi-Dimensional Traffic Accident Analysis System Based on GIS

为适应交通运输系统信息化发展态势,充分有效地利用海量的交通事故数据,提出了一个交通事故的多维数据概念模型,讨论了基于ROLAP的多维数据模型的实现方法,探讨了一种GIS与OLAP的集成模型,提出了基于GIS的交通事故多维分析系统的框架。

In response to the demand of traffic information system,the author puts forward a multi-dimensional data model of traffic accident,discusses the implementation of the model based on ROLAP,analyses the integration mode of GIS and OLAP,and proposes a framework of GIS-based Multi-Dimensional Traffic Accident Analysis System.
