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 roadway.
Collapses all items in the tree view.
Expands all items in the tree view.
Specifies a station 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 station along the alignment.
Deletes the selected region or station.
Displays the Superelevation Import dialog box. Click and browse to the location of the CSV file you want to import.
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.

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 station, right-click a region or a parameter Add Station.
Critical Stations include:
Displays the start station and end station. When you edit these fields for a Runout or Runoff region or a critical station, the distance field and rate of change field are updated. If the station you edit is the same as the Start Station or End Station of a Runout or Runoff region, that station value is also updated and the transition formula (% into tangent or spiral) is not maintained.
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 station values and the rate of change field. The station value(s) update with respect to the beginning or end of curve. The station 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.
and then change the Runoff value to 150 feet, you get the following results:
Any other stations or regions associated with the superelevation curve shift by the same amount.
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.
Specifies the change in slope over the distance between one critical station and the previous (sequential) critical station for each lane. If you make changes to this field, the stations and distance values stay the same and the slope values changes accordingly. (This column is hidden by default).
Displays the curve smoothing if the option for curve smoothing was specified in the Superelevation wizard. (This column is hidden by default)
Changes in lane columns are reflected in the rate of change value associated with the lane that you edit.
