Superelevation Point Properties (Right mouse click on point and select "Edit Point".)

Name - displays the point name. This is a read only field. The point name is based on the control line and the point’s station value. It is automatically changed when the point is moved. Use the locate button to identify points.

Station - specifies the station location of the point. Depending on the constraints, you may be able to change the station value of the point.

Cross Slope - specifies the cross slope value of the control line at the point. Depending on the constraints, you may be able to change the cross slope value of the point.

Type - specifies the point type. The point type is initially set by the wizard, you can modify it. Valid types are: Undefined, Normal Crown, Super Runoff, Reverse Crown or Full Super. Type is used primarily for reporting and for display.

Constraints - Constraint types superelevation points include Horizontal, Vertical, Slope, Vector Offset, and Mirror Cross Slope. A "Mirror Cross Slope" constraint uses the zero percent superelevation line to mirror the opposite side superelevation rate. Slope constraint (%) is calculated by taking the difference in superelevation rate / horizontal distance.
Apply - executes the command.

Close - dismisses the dialog.

Previous - returns to the previous point.

Next - proceeds to the next point.

Move Superelevation Point (Right mouse click on point and select "Move point".)

Depending on how the point is constrained, it can be moved horizontally, vertically, or at a fixed slope. Option to key in the desired station and superelevation rate in "XX+XX.XX,X%" format.

Snap To:

Cardinal Points - Option to snap to the horizontal alignment key cardinal points such as the POB, PC, PT, TS, SC, CS, ST, PRC, PCC, and POE.

Superelevation Points - Option to snap to other superelevation points.
Superelevation Display List (Right mouse click and select "Superelevation Display List".)

Manages which section control lines are displayed.

Superelevation Sections - lists all superelevation sections. You can display control lines by section. When you select a section, the control lines are highlighted in the Available Superelevation list.

Delete - removes the selected section(s) from superelevation.

Available Superelevations - lists all available control lines base on the selected Superelevation Sections.

Delete - removes the selected control line from superelevation. The parent Superelevation Sections are still available.

All - selects all control lines for display.

None - deselects all control lines.

Apply - displays the control lines.

Close - dismisses the dialog.

Create Single Control Line - Creates a new superelevation control line.
Name - key in new control line name.

Parent Section - specifies the parent section name. Because a control line belongs to a section, any of it's points can be constrained by any other points in that section. The points of a control line cannot be constrained by points from another section.

Input Type:

Existing Graphics

Copy From - identifies the control line that is copied to create a new control line. When copying from another superelevation control line, a point with the maximum cross slope is inserted at any point where the copied control line has a full superelevation point. In the new control line, a point with a normal crown value is also inserted wherever there is a normal crown point in the copied control line.

Copy Values from original - indicates, when checked, that all of the values of the original control line are copied.

Mirror All - indicates, when checked, that the inverse of all of the control line values are created.

Excluding Normal Crown - indicates, when checked, that the inverse of all of the control line values, except normal crown, are created. This option requires the point type to be specified in the Superelevation > Superelevation Point Properties > Type field available from the Create Superelevation Wizard.

Normal Crown - specifies the crown value.

Maximum Cross - specifies the maximum cross slope value.

Table

Tabular Input

Input Grid - allows you to key in station and cross slope and select the point type. When you key in a station value on the bottom line, the cross slope and type will automatically be populated with the values from the last entry, and a new blank row will be added to the grid.

Insert Button - inserts a row in the grid before the current row. The new row values will be initialized using the current row values.

Delete Button - deletes the current row.

Import Button - allows you to import an Excel spreadsheet into the grid. The spreadsheet format is (Station, Cross Slope) in the first two columns of the sheet.

Import Superelevation from ASCII - allows for selection of Excel spreadsheets (*.xls, *.xlsx) for import. The format must be (Station, Left Slope, Right Slope) in the first three columns of the sheet.
Edit Curve Set Stations - (Right mouse click and select "Edit Curve Set Stations".)

Reviews and/or modifies calculated runoff and runout values. This command includes colored text to indicate a condition of the design data. Red station text identifies stations beyond the current curve set.

Section Name - displays the name of the current section being processed.

Curve Set - displays the current curve set ID number.

Show Curve Set Information - shows, when selected, all of the current curve set information on the right side of the dialog.

(Station Information) - displays station information on all the superelevation control keypoints.

Type - shows the point type.

Constrained - indicates whether or not the point on the superelevation control line is constrained. Enable/disable a constraint by selecting this check box.

Station - shows station location of the point. You can modify this value only if it has not been constrained.

Cross Slope - shows the cross slope at the point.

Length - shows the length between the current point and the previous point.

Grade - shows the grade of the vertical profile at the station.

- allow you to add and remove points from the displayed list.

Design Check Data - applies design checks. Enter design check data in the text box. If a valid table is loaded, the design checks are automatically applied.

Any full super points that are outside the range of the +/- 0.5% from the table rate determined by the radius are flagged in Red.

Any transition lengths that are less than the table transition (2 lane) are flagged as Red.

For Runoff, it is the sum of length between Super Runoff and Full Super.

For Total Transition, it is the sum of lengths between Normal Crown and Full Super.

Apply - executes the command.

Undo - removes the most recent change in the dialog. Also applicable to the Move or Edit superelevation point commands.

Close - dismisses the dialog.

2. Profile View

Colors of the superelevation profile view corresponds to the below plan view.

Right mouse click anywhere in the Profile View to open the Profile Display List. Select the various profiles to display or not display.

3. Plan View

In superelevation display mode, the plan view displays the top of the backbone in colors that represent the cross-slope values of the backbone surface. Green-Blue colors represent slopes from 0.5% to 10% to the right with dark blue representing slopes greater than 10% to the right. Yellow-Red colors represent slopes from 0.5% to 10% to the left with dark red representing slopes grater than 10% to the left. Slopes less than 0.5% are represented as white.

4. Cross Section View

Colors of the superelevation cross section view corresponds to the above plan view.
