the questions hidden in the arc-length positioning of the spiral curve in highways were discussed
and the problems with using feature parameter A upon the spiral curve positioning were analyzed. It presents the spiral curve arc-length equation and its using superiorities
based on the research of the osculation theory in geodesic line. Examples were given to illustrate the positioning technique depending on the spiral curve arc-length equation. There are 4 conclusions
which are of great scientific and technological significance.
