Abstract: 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.
