城市交通仿真实验系统的面向对象开发

An Object-oriented Development of Urban Traffic Simulation Laboratory System

依据面向对象软件开发思想,首先对城市道路交通系统进行了实体分析,并由此确定了城市道路交通仿真系统的主要对象类。在此基础上进一步进行了对象建模工作,提出了反映对象类之间静态关系的静态对象模型以及反映仿真系统运转机制和控制结构的动态对象模型。最后,根据对象建模的结果进行了详细的对象设计,确定了各主要对象的属性和功能。

According to the object-oriented software development concept, this paper provides an entity analysis of the urban road traffic system firstly and thereafter defines the main object classes of the urban traffic simulation system. Furthermore, the static object models which describe the static relation among object classes and the dynamic object models which represent the operating mechanism and control structure of simulation system are put forward. Finally, based on the object modeling results, the detailed object designs including the definition of objects attributes and functions are given.
