Superelevation Tabular Editor (Panorama)

View and edit superelevation data for each curve or enter data manually.

The information that is displayed in the Superelevation Tabular Editor varies depending on the type of carriageway.

Note: Edits you make in the Superelevation Tabular Editor or the Superelevation View are dynamic. Changes made in one are reflected in the other.

Collapses all items in the tree view.

Expands all items in the tree view.

Add A Superelevation Critical Chainage

Specifies a chainage along the alignment. Select a row in the editor and click , the tabular editor temporarily closes and the command line prompts you to pick a chainage along the alignment.

Delete Critical Chainage or Superelevation Region

Deletes the selected region or chainage.

Import Superelevation Data From File

Displays the Superelevation Import dialog box. Click and browse to the location of the CSV file you want to import.

Export Superelevation Data

Displays the Export to CSV dialog box. Browse to the location where you want to save the CSV file. All data that is visible in the Superelevation Tabular Editor is saved in the CSV file.

Undo

Recovers the most recently changed data in the Superelevation Tabular Editor.

This button affects:

• changed value in a cell
• import of a CSV file
• calculation from the Superelevation Curve Manager or Calculate Superelevation wizard
• addition or removal of a critical chainage
• removal of a transition region

Redo

Recovers the data that was reverted using Undo in the Superelevation Tabular Editor.

This button affects:

• changed value in a cell
• import of a CSV file
• calculation from the Superelevation Curve Manager or Calculate Superelevation wizard
• addition or removal of a critical chainage
• removal of a transition region

Clear All Superelevation Data

Removes all superelevation data, including data in cells, critical chainages, and transition regions.

Columns

Superelevation Curve

This column displays the Transition In and Transition Out Regions for the curves in the alignment.

Expand each region to view or edit the superelevation parameters.

To manually add a new critical chainage, right-click a region or a parameterAdd Chainage.

Critical Chainages include:

• Begin Normal Crossfall
• Begin Normal Shoulder
• Begin Full Super
• End Full Super
• End Normal Crossfall
• End Normal Shoulder
• Level Crown
• Low Shoulder Match
• Reverse Crossfall
• Shoulder Breakover
• Begin Shoulder Rollover
• End Shoulder Rollover

Start Chainage and End Chainage

Displays the start chainage and end chainage. When you edit these fields for a Runout or Runoff region or a critical chainage, the distance field and rate of change field are updated. If the chainage you edit is the same as the Start Chainage or End Chainage of a Runout or Runoff region, that chainage value is also updated and the transition formula (% into straight or transition) is not maintained.

Length

Displays the length for the Transition In Region and the Transition Out Region. Specifies the length for the Runout and Runoff. Editing the length value changes the chainage values and the rate of change field. The chainage value(s) update with respect to the beginning or end of curve. The chainage value associated with curve start and end changes when you change the distance values to maintain the percentage of transition shift into the specified curve.

For example: without changing any of the other distance values.

• 30% of transition length should be into the curve
• Start Chainage of Runoff is 1+00
• End Chainage is 2+00
• Beginning of Curve chainage is 1+70

and then change the Runoff value to 150 feet, you get the following results:

• 30% of transition length should be into the curve
• Start Chainage of Runoff becomes 0+65
• End Chainage of Runoff becomes 2+15(to maintain the transition length at 30% into the curve)
• Beginning of Curve chainage is 1+70

Any other chainages or regions associated with the superelevation curve shift by the same amount.

Overlap

Displays the warning symbol for areas on the alignment where there is overlap. Click the , and a task dialog box is displayed showing the options to resolve overlap. The conditions are either a reverse curve situation or a compound curve situation. To automatically resolve overlap you can select the option on the Attainment page in the Superelevation wizard. However, there can be situations where overlap is created by manually editing or by importing superelevation data.

Rate of Change

Specifies the change in slope over the distance between one critical chainage and the previous (sequential) critical chainage for each lane. If you make changes to this field, the chainages and distance values stay the same and the slope values changes accordingly. (This column is hidden by default).

Curve Smoothing

Displays the curve smoothing if the option for curve smoothing was specified in the Superelevation wizard. (This column is hidden by default)

All Lane Columns

Changes in lane columns are reflected in the rate of change value associated with the lane that you edit.
