公路勘测设计的CAI软件设计

The CAI Used for the Highway Survey and Design

公路勘测设计是交通工程专业学生的必修课，具有较强的实践性。传统的封闭式教学模式虽可系统传授理论知识，但在培养学生设计能力方面却有较大的局限性。为突破这一局限，公路勘测设计CAI软件利用计算机强大的计算和绘图功能，以及处理交互信息的独特优势，对公路设计的实际过程进行模拟及演示。较为详细地介绍了公路勘测设计 ＣＡＩ软件的总体设计方案，系统的核心模块──模拟设计模块，数据流图，以及软件开发所使用的编程语言。

As a compulsory course for those majoring in traffic engineering, Highway Survey and Design is very practical. Though the traditional and close teaching mode. it can teach student theoretical knowledge systematically, has rather great limitation for developing students' ability of designing highway. To break through this limitation, the software simulates and demonstrates the actual process of designing a highway, taking advantage of the strong computation and drawing ability and particular advantage of processing mutual information of computer. this article expatiates the general design scheme, the core module, simulated design and the diagram of data flow of the software, It also introduces the computer language it uses.
