摘要
地理信息系统 (GIS)在智能交通系统 (ITS)服务的各个领域中的框架定位作用越来越重要。和定位作用一样 ,GIS的空间决策支持作用已逐步应用于ITS的各个服务领域。本文通过对普通GIS空间决策支持作用的分析 ,提出面向ITS的GIS不仅可以对交通信息起空间定位作用 ,而且可以运用其对空间数据的分析能力 ,通过与交通专业的结合 ,在ITS的各个服务领域起决策支持作用。同时 ,根据ITS对GIS决策支持的要求 ,提出了面向ITS的专题GIS应具有的特点。
GIS is more and more important in framework orientation in every field of ITS. As the role of orientation, Supporting of GIS decision-making gradually applies to every ITS service field. This paper puts forward that GIS oriented ITS not only plays an orientation role in transportation information by analyzing common supporting role of GIS decision-making, but also uses analysis capacity of special data to make decision in every service field of ITS by combining with transportation specialty. In the meanwhile, characteristics of GIS and ITS are putted forward according to the requirement to GIS decision-making that ITS needs.
