Working with superelevations in the OpenRoads SS4 release is much different from previous versions of InRoads or GEOPAK. Here are 5 things to know when when you start defining your first superelevations.
1. Superelevation has to be built in its own CAD file
Once the 2D file is created it is referenced and associated with the corridor.
2. Superelevation in a Color Coded Display
After you have created your superelevation sections and lanes you will want to view your superelevation in the MicroStation view.
- In the View Attributes dialog toggle ON Fill
3. Superelevation Flag
For each template point that you wish to be controlled by superelevation, you need to toggle ON the Superelevation Flag. Allowing OpenRoads to control the point even during horizontal transitions.
4. Adjust Superelevation in the view using Textual Manipulators
By selecting the calculated superelevation graphics in the MicroStation view; the Textual Manipulators will appear allowing you to modify either the station value or the superelevation value.
5. Place Temporary Dimension Lines to help evaluate your superelevation
In cross section view, consider placing a temporary dimension line to evaluate lane slope and width.
