Using the route coordinate system, a three-dimensional mathematical model of highway is established according to horizontal alignment, vertical alignment, cross section and broken chains etc. in route design files. A transformation model between the route coordinate system and the con- struction coordinate system is also set up. The necessity and the data structure of the computer-aided
