Design Rules

In this section you specify the tables to use for superelevation rate, transition length, and attainment method.

Design Speed

Displays the design speed for the curve group. This value is derived from the Design Criteria tab of the Alignment Properties. If the curve group has two or more design speeds, the highest design speed is displayed.

Design Criteria File Name

Specifies the name of the design criteria file. This file defines minimum radius tables, superelevation attainment methods and formulae, superelevation rates and transition lengths for various roadway types and design speeds. Click in the cell to browse to the location of the design criteria file.

Superelevation Rate Table

Specifies the name of the superelevation rate table used to determine the maximum superelevation rate for the curve group. Click the arrow to display a list of the superelevation rate tables associated with the specified design criteria file.

Transition Length Table

Specifies the name of the superelevation transition length table used to calculate the transition stations for the curve group. Click the arrow to display a list of the transition length tables associated with the specified superelevation rate table.

Attainment Method

Specifies the name of the superelevation attainment method for the curve group. Click the arrow to display a list of the attainment methods associated with the specified design criteria file.

Default Options

In this section, you specify the general settings used to calculate superelevation specifications.

Corridor Type

Specifies the type of roadway as Undivided (single carriage way) or Divided (dual carriage way).

Cross Section Shape

Specifies the cross sectional shape of the roadway as Planar or Crowned:

 Planar: There is no change in slope between the travel lanes.

 Crowned: When no superelevation is applied, travel lanes slope downward in opposite

directions from a common crown point.

Highside Location

Specifies the default Highside Location for planar roads.

 Left Edge: Specifies that the high side of the roadway is on the left edge on tangent

(unsuperelevated) sections when the corridor type is Undivided and the Cross Section Shape is planar.

 Level: The roadway is level (0% slope) on tangent sections.

 Right Edge: Specifies that the high side of the roadway is on the right edge on tangent

(unsuperelevated) sections, when the corridor type is Undivided and the Cross Section Shape is planar.

(16)

Nominal Width - Pivot To Edge

Specifies the typical width of the roadway from the superelevation pivot point to the outer edge-of-traveled way. Some superelevation attainment methods require that you specify this value in order to calculate the length of the superelevation transition.

Outside Shoulder Superelevation Method

Specifies the method that is applied to the outside shoulder during superelevation:

 Default Slopes: Default slopes are retained and shoulders are not superelevated.  Match Lane Slopes: Shoulder slopes match the slopes applied to the adjacent traveled

ways through out the superelevation process.

 Breakover Removal: Shoulders on the outside edge of the curve are adjusted upward

to match the Normal Lane Slope (%) before the lane begins to superelevate. The high-side shoulder slope matches the high-high-side lane slope throughout the superelevation process, and it then rotates downward back to the Normal Shoulder Slope (%) value when the lanes are back to the un-superelevated condition.

Inside Shoulder Superelevation Method

Specifies the method that is applied to the inside shoulder during superelevation:

 Default Slopes: Default slopes are retained and shoulders are not superelevated.  Match Lane Slopes: Shoulder slopes match the slopes applied to the adjacent traveled

ways through out the superelevation process.

 Breakover Removal: Shoulders on the outside edge of the curve are adjusted upward

to match the Normal Lane Slope (%) before the lane begins to superelevate. The high-side shoulder slope matches the high-high-side lane slope throughout the superelevation process, and it then rotates downward back to the Normal Shoulder Slope (%) value when the lanes are back to the unsuperelevated condition.

If you are adding superelevation to any alignments,

do so before creating the corridor. Also, the

superelevation data is not dynamic, so it does not

update if you grip-edit the alignment. Therefore, add

the superelevation after the alignment design is

stable, or be prepared to redo the superelevation if

the alignment is modified.
