The Widenings Card
Roads Edit Roads ( New… or Edit… ) Widenings .
The Widenings card of the New Road screen is used to add or edit
widenings.
A widening is a section of a road that changes in width,
but does not necessarily require any new templates. The
road width is adjusted by changing only the width of the
first segment of the template that leads into the
beginning of the widening. Any additional segments,
like those that may describe a sidewalk or ditch, are not
adjusted.
The following rules must be considered when adding a
widening to a road:
• A widening must have a starting station and an
ending station or a length.
• Left and right widenings are separate and
independent of each other.
• The start and end stations must occur within the boundaries
of the alignment.
• The starting station must occur before the ending station.
• The beginning of a widening must match the width of the
previous widening or template.
• The end of a widening must match the next template or
widening unless it is the last element in the road.
• The beginning or ending of a widening cannot occur within
the boundaries of another widening, but the beginning of one
widening can occur at the same station as the end of a
previous widening.
• Widenings are always positioned by their start station.
Add… : When a widening or is selected from the L or R
columns in the Widenings card, this button opens the Add Widening
screen, which allows you to add a widening to the same side of the
road that was selected.
