基于UML城市道路交通状态判别技术应用研究

UML Based on Research of Technologies Applications in the Identification of Urban Road Traffic Conditions

面向对象的方法是开发新的信息系统的首选方法,在业界,统一建模语言UML已成为在构建面向对象系统的分析与设计所使用的标准语言。深圳城市道路交通拥挤自动判别系统,是通过对拥挤状态下交通特性进行分析和对ACI算法的适用性条件与需求进行研究,应用MVS设计模式和J2EE设计模式对软件基本功能进行设计。通过典型的用例实现阐述软件的实际工作方式,解释不同的详细设计模型元素如何促成功能的实现。用层次化的结构逐一说明重要的设计包及其依赖关系,详细列出设计包中重要设计类的基本属性、主要操作及协作者,并对核心操作进行具体说明。

Nowadays,object oriented methodology is the most popular for developing information systems,and the Unified Modeling Language becomes a standard language for the analysis and designing phase in developing an object oriented system.The ShenZhen Urban Road Traffic Condition Identification System,which focuses on the analysis of the characteristics in traffic congestion,and the applicability of the ACI algorithm.In this paper,we apply MVS pattern and J2EE technology into the design of this system,and explain the working process of the software by typical use cases.We also illustrate the model elements for the key functions,and present the hierarchy of important packages and the dependencies,including the basic properties,operations and collaborators of the classes.
