2. Any two templates without intervening Widening or Super
Elevations will transition.
• This means that each template segment will transition at a
linear rate from its existing offset from the centerline to the
new offset from the centerline as defined by the new template.
3. A template’s first segment slope and/or width will be modified
when:
• A template is located within a Super Elevation or Widening
definition including starting and ending stations and inside
Widening or Super Elevation transition areas.
• Templates will acquire first segment slope value from the
Super Elevation definition, and/or acquire its first segment
width value from the Widening definition.
4. Only one template may occupy any station.
• As little as 0.001 units can be used to separate templates.
Widenings and Super Elevations.
1. Super Elevation and Widening stations must be within the
station range of the alignment.
2. Super Elevations and Widenings follow the same rules except
that the start and end stations of a Super Elevation are defined
by:
• Super Elevations will start their transitions at a point equal
to the user defined starting station minus ½ of the starting
parabolic transition length if parabolic transitions are used.
• Super Elevations will start their transitions at a point equal
the user defined ending station plus ½ of the ending parabolic
transition length if parabolic transitions are used.
3. Super Elevation start slope value and Widening start width value
must match the first segment value defined by:
• A previous Super Elevation or Widening. (Priority)
• A previous Template.
