Radius of Curve (X)

When 3-Centered Arcs is selected as the curb return type, this option lets you specify the radius for each of the three curves on the curb return.

Length of Curve (X)

When 3-Centered Arcs is selected as the curb return type, this option lets you specify the length for the first and third curves on the curb return.

Chamfer Fillet Length - Along Incoming\Outgoing Lane

When Chamfer is selected as the curb return type, this option lets you specify the length of the curb return’s chamfer fillet along the incoming or outgoing lane.

Default Widening Parameters

Use these settings to specify the default styles assigned to intersection creation. For more information, see Widenings, or Editing Offset Alignments and Widenings.

Widening At Incoming Lane

Specifies whether to widen the incoming lane as it enters the intersection.

Widening At Outgoing Lane

Specifies whether to widen the outgoing lane as it exits the intersection.

Widened Offset

Specifies the offset distance applied to the widened regions, at both the entrance to the intersection, and as it exits the intersection.

Widening Segment Length

Specifies the length of the widened portion of the curb return at both the entrance to the intersection, and as it exits the intersection.

Transition Type

Specifies the type of transition used for the widening: Linear, Curve-Line-Curve, Curve-Curve -Reverse Curve, or Curve - Reverse Curve.

Linear Transition Type

When Linear is selected as the Transition Type, this option lets you specify the type of linear transition used for the widening: By Length or By Taper Ratio.

Transition Length

When By Length is selected as the Linear Transition Type, this option lets you specify the length of the transition for the widening.

Taper Ratio

When By Taper Ratio is selected as the Linear Transition Type, this option lets you specify the ratio of the tapering for the widening.

Radius of Curve X

When a curve option is selected as the Transition Type, this option lets you specify the radius for the first and second curves used in the widening.

Radius of Reverse Curve

Distance Rule to Adjust the Grade

Specifies the method that is used to adjust the grade of the secondary road profile. When To Intersection Extents is selected, the grade of the secondary road profile is adjusted to within the extents of the intersection object. When Specify Distance is used, the grade of the secondary road profile is adjusted by the value that is entered in the Distance Value.

Distance Value

Specifies the distance that is used to adjust the incoming and outgoing grade along the secondary road profile when Specify Distance is selected for Distance Rule to Adjust the Grade.

Specifies whether to extend the curb return profile along the outgoing lane of the intersection.

Length To Extend Along Outgoing Lane

When Extend Profile Along Incoming Lane is set to Yes, this option lets you specify the length to extend the curb return profile along the outgoing lane of the intersection.
