Data

Enter the name of the road.

Optionally, select the surface to be used to define the road.

Although a surface is not required to create a Road file, it is required to create cross-section templates for the file.

Select the horizontal alignment to be used to define the road.

If you selected a surface that includes a horizontal alignment, that alignment is selected by default.

Optionally, select the vertical alignment to be used to define the road.

If you selected a horizontal alignment that includes one or more associated vertical alignments, one of those vertical alignments is selected by default; any additional vertical alignments are available for selection in the drop-down list.

If you selected a surface and a horizontal alignment, you can select to generate a new vertical alignment by selecting Auto Generate in the drop-down list.

Although a vertical alignment is not required to create a Road file, it is required to create cross-section templates for the file.

Enter the station IDs that specify the horizontal starting and ending points for the road.

If the road includes a vertical alignment, the stations must be within the range where the horizontal and vertical alignments overlap.

Specify the left and right offset distances required to include all strings you want to use to define the road.

File name

Select or enter a name for the Road file (.rxl or .dc), and select the location to which you want to store it.

Settings

For RoadXML(.rxl) only, select the version of RoadXML to which you wish to import.

Select one of the following options:

• Sample interval - Select to generate cross-section templates based on cross-section samples taken at specified intervals along the horizontal alignment.
• Control point- Select to generate cross-section templates based on cross-section samples taken at surface control points (vertices).

If you selected Sample interval for the Template generate method, enter the distance between each sample.

Enter a value for the tolerance to be used to help determine which cross-section samples will be not be used to create cross-section templates.

If a sample falls within this tolerance based on samples preceding and following it, no cross-section template is created for that sample.

By preventing the creation of unnecessary redundant cross-section templates, the size of the Road file can be greatly reduced.

For more information, see Notes on Cross-Section Templates.

Select whether to adjust for arc and/or chord offset, which shifts cross-section templates for curvature alignment.

Select one of the following options:

• None - Select if you do not want to define a side slope element.
• Append - Select if you want to define a side slope element appended to the last strings.
• Replace - Select to define the side slope element based on last strings already in the road surface.

Do one of the following to specify the last strings to be used to create the side slope element:

• Enter a regular expression (match pattern) that identifies one or more last strings you want to specify for the side slope element. For more information about using regular expressions, see Reference: Regular Expressions.
• Leave blank to enable the software to use all of the last strings included in the road surface to create the side slope element.

Do one of the following:

• Enter a code for the side slope element.
• Leave blank to enable the software to generate codes for the side slope elements based on the last strings it finds.

Enter the cut slope grade for the side slope element.

Enter the cut ditch width for the side slope element.

Enter the fill slope grade for the side slope element.

Enter the station interval for the horizontal alignment when drawn on the field device.
