spContent=Road infrastructure is the artery of social and economic activities, supporting the development of national economy and the improvement of people's living. If architecture is the solidified music, then road is the flowing note which coordinates with the environment in a harmony way. Aside from aesthetic nature, road places an important role in the connection of regional economy, the layout of urban scale and the quality of travel. The course "Road Survey and Design" is to unveil the selection and design of roads.

常见问题
Q: Can I just watch videos to learn the course?
A: Negative. This course involves some basic theories, which are suitable for learning by watching videos, but also contains calculations, which need to be consolidated after class.
Q:Why does Chapter 8 include CAD design?
A: This course has a strong practical attribute. By introducing CAD software into the course, students can skillfully use industry tools to solve practical problems, which is not only one of the requirements of this course, but also a major feature of this course.
