| Abstract: | In this paper, the research of automatic calculation of the shortest distance between the centre-line of a highway and control points beyond the route is discussed,which has relation to computer-aided design about plane alignment design in route selection of highways. The method of swinging approach on compressible step size which can be applied to calculate the shortest distance between the centre-line of a highway and control points beyond the route is first put forward. This method is practicable in all kinds of plane alignment designs of highways. |
