This subassembly creates a cross-sectional representation of a lane comprised of multiple layers. The layers can be of varying widths. It also applies the Outside Lane superelevation slope value for the corridor model's baseline alignment.
Attachment
The attachment point is at the inside edge of lane on the finish grade surface. This component can be attached to either the left or right side.
Input Parameters
Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Target Parameters
This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing. For more information, see To Specify Corridor Targets.
| Parameter | Description | Status |
|---|---|---|
| Lane Width | May be used to override the fixed lane Width and tie the edge-of-lane to an offset alignment. The following object types can be used as targets for specifying this: alignments, polylines, feature lines, or survey figures. | Optional |
| Outside Elevation | May be used to override the normal lane slope and tie the outer edge of the travel lane to the elevation of a profile. The following object types can be used as targets for specifying this elevation: profiles, 3D polylines, feature lines, or survey figures. | Optional |
Output Parameters
| Parameter | Description | Type |
|---|---|---|
| Lane Width | Width of the lane | Numeric |
| Lane %Slope | % slope of the lane | Numeric |
Behavior
Each layer has its own separate extension options both on the inside and outside. The inside and outside extensions specify the additional width on the inside or outside relative to the pavement layer immediately above.
Example 1:
In the following example, the Pave4 Inside Extended Width is 0.5 meters. The Pave4 Outside Extended Width is zero. If this subassembly is inserted on the right side, it is drawn as shown in the following illustration.
Example 2:
In the following example, the Pave4 Inside Extended Width is 0.5 meters. The Pave4 Outside Extended Width is 0.6 meters. If this subassembly is inserted on the right side, it is drawn as shown in the following illustration.
The extension widths will always be specified as positive widths.
The pavements layer widths may be specified using the following methods:
- by specifying that the pavement width be the same as the pavement immediately above
- by specifying a pavement width
- by specifying an inside and outside pavement layer extended width so that pavement layer width will be the distance between the inside and outside offsets
- by specifying an inside pavement layer extended width and pavement width so that the outside pavement layer is automatically calculated
Breakover removal is required if there is a change in slope of pavement while applying superelevation.
Layout Mode Operation
In layout mode, this subassembly displays the links defined by the input parameters.
