Station Equations define adjustments for the stationing
values in the Horizontal Alignment File. These adjustments
may be necessary when the horizontal alignment has been
modified by inserting or removing a constituing element and
the stationings in the Horizontal Alignment File were not
recomputed. This can be the case when editing manually or
with a program which does no automatic recomputation.
Simply speaking, station equations define leaving a gap or
allow an overlap at certain stations.
The
constituting elements
in the equations are
•
station back
•
station ahead.
