高等级公路安全控制系统计算机辅助设计技术的研究与开发

Study and Development of CAD Technique for Traffic Engineering

鉴于中国交通工程ＣＡＤ系统的设计手段不能适应高等级公路飞速发展的需要，交通工程ＣＡＤ系统作为国家“八五”科技攻关项目，取得了满意的结果，并已通过国家验收。此项技术采用先进的计算机图形处理技术与计算机辅助设计相结合的方法，为提高中国高等级公路交通工程的设计质量，发挥良好的作用，显示出较高的经济效益和社会效益。本文对该ＣＡＤ系统的研究开发进行了系统的研究。

Nowadays the traditional method cannot fit the demands of freeway traffic engineering designing and drawing. Based on the advanced computer graphic and computer aided design technique, the freeway traffic engineering CAD system was successfully developed. With this CAD system, the engineer can improve the design of freeway traffic engineering system. It has shown us the higher economic and society benefit. This paper presents a brief introduction of the freeway traffic engineering CAD system.
