7
In the second row, enter the following parameters:
■
Start Station: 0+820.00
■
Design Speed: 70 km/h
8
Click OK.
In the Superelevation Curve Manager dialog box, the Design Speed value
did not change because the station at which you changed the design
speed is located after Curve.3.
9
Click Next.
Under Superelevation Curve Details, for Curve.4, the Design Speed value
is 70 km/h, which is what you specified in the preceding steps.
At the bottom of the dialog box, the Superelevation status is displayed
as *Out of Date*. Applying the new design speed to this curve caused the
superelevation data to become out of date. In the following steps, you
will recalculate the superelevation data for this curve to accommodate
the new design speed.
Calculate superelevation for an individual curve
1
Click Superelevation Wizard.
The Calculate Superelevation dialog box enables you to select which
curves to recalculate.
2
Select This Curve Only. Click OK.
The Calculate Superelevation wizard enables you to specify the parameters
used for the calculation. The parameters you specify in the wizard apply
to only the curves you selected in the Calculate Superelevation dialog
box in Step 1. For example, if you specify a different attainment method
or criteria file, then those parameters will not match the rest of the curves
in the alignment. In this exercise, you will accept most of the default
settings.
3
In the Calculate Superelevation wizard, click Attainment.
4
On the Attainment page, for Superelevation Rate Table, select AASHTO
2001 eMax 6%.
5
Under Curve Smoothing, specify the following parameters:
■
Apply Curve Smoothing: Selected
■
Curve Length: 30
