基于组件的智能交通信息系统设计研究

Study on Designing Component-Based Information System of the Intelligent Transportation System

随着智能交通系统(ITS)的飞速发展,交通功能的不断增加,与ITS配套的信息系统日趋庞大复杂。传统的软件工程设计思想,不能满足日益增长的ITS信息系统发展的需要。该文提出了软件工程中基于组件发展(CBD)的思想规划设计ITS信息系统。详细阐述了组件技术构造ITS信息系统各部分的方法,并以统一建模语言(UML)和形式化语言Z描述了组件构成。最后,指出基于组件发展思想是下一步构造组件库的必然方法,是将来ITS信息系统以体系结构为中心和模式化发展的基础。

The information system of the Intelligent Transportation System is a very complex system.The paper mainly deals with how to construct the system efficiently.It introduces the component-based development (CBD)method into the information system of the ITS,briefly discusses components of each part,and applies the Unified Modeling Language(UML )and the formal method Z language to define the component.The paper provides a promising thought on the information system development of the ITS.
