Techniques for automating the design of highways are examined. It is accepted design practice to reduce the straight‐line parts of the horizontal alignment of a designed center line as much as possible. This can be accomplished manually by using clothoid templates. This article describes the use of spiral splines that behave in a manner such that the horizontal alignment may be automatically designed as a composition of clothoid segments. The resulting methods are suitable for microcomputer implementation.
