Calculate Superelevation - Roadway Type Page

Use this page of the wizard to specify the roadway type.

Pivot Method

Specify the default Pivot Method, which specifies the axis about which the corridor is superelevated.

Center Baseline: Specifies that the superelevated corridor pivots about the assembly baseline.
Inside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the inside of the curve.
Outside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the outside of the curve.
Left Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the left side of the assembly.
Right Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the right side of the assembly.

Pivot Method

Specify the default Pivot Method, which specifies the axis about which the corridor is superelevated.

Center Baseline: Specifies that the superelevated corridor pivots about the center of the lane.
Inside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the inside of the curve.
Outside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the outside of the curve.
Left Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the left side of the assembly.
Right Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the right side of the assembly.

High Side Location

Specify the default Highside Location for planar roads.

Left Edge: Specifies that the high side of the roadway is on the left edge on tangent (unsuperelevated) sections when the corridor type is Undivided and the Cross Section Shape is planar.
Level: The roadway is level (0% slope) on tangent sections.
Right Edge: Specifies that the high side of the roadway is on the right edge on tangent (unsuperelevated) sections, when the corridor type is Undivided and the Cross Section Shape is planar.

Pivot Method

Specify the default Pivot Method, which specifies the axis about which the corridor is superelevated.

Centers: Specifies that the superelevated corridor pivots about the crown.
Inside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the inside of the curve.
Outside of Curve: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly that is closest to the outside of the curve.
Left Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the left side of the assembly.
Right Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the right side of the assembly.
Median Edges: Specifies that the superelevated corridor pivots about the edges of the median.
Baseline: Specifies that the superelevated corridor pivots about the baseline, and the axis of rotation calculation is not performed.. Axis of rotation behavior is determined by the way that the assembly is constructed.

Median Treatment

Specify whether the median maintains its shape or distorts as the corridor superelevates.

Maintain Median Shape: The median may be raised or lowered as the corridor superelevates, but the median geometry does not change.
Distorted Median: The width of the median remains the same, but either side can be raised or lowered as the road superelevates, which vertically distorts the median shape.

Note: When the Pivot Method is set to either Centers or Median Edges, the Median Treatment must be Maintain Median Shape.

Right Side: Specifies that the superelevated corridor pivots about the edge of pavement of the subassembly on the right side of the assembly.
Median Edges: Specifies that the superelevated corridor pivots about the edges of the median.
Baseline: Specifies that the superelevated corridor pivots about the baseline, and the axis of rotation calculation is not performed.. Axis of rotation behavior is determined by the way that the assembly is constructed.

Median Treatment

Specify whether the median maintains its shape or distorts as the corridor superelevates.

Maintain Median Shape: The median may be raised or lowered as the corridor superelevates, but the median geometry does not change.
Distorted Median: The width of the median remains the same, but either side can be raised or lowered as the road superelevates, which vertically distorts the median shape.

Note: When the Pivot Method is set to Median Edges, the Median Treatment must be Maintain Median Shape.
