Adjust superelevation (slope and banking angle) for full width of road
The Road Superelevation Tool enables you to adjust the superelevation (slope and banking angle) for the full width of a road at specified distances. To modify the slope or banking angle at specified cross-sections of a road, use the Cross Section Tool instead.
On the RoadRunner toolbar, click the Road Superelevation Tool button:
FourWayStop.rrscene scene, which is one of the
prebuilt scenes that is included with newly created RoadRunner projects. Zoom in on the scene and rotate the camera to view the scene
at an angle. All roads in this scene are flat.
Click the Road Superelevation Tool button.
Click to select one of the roads. Then, in the Attributes
pane, set the Angle attribute to
degrees. The banking angle of the road increases by 10 degrees along the length of the
Right-click at a point along the road to add a superelevation node. The node appears as a red bar across the width of the road, with smaller green tangent nodes for adjusting the slope at this node. To adjust the position of the superelevation node along the road, click and drag the red bar.
In the Attributes pane, decrease the
Angle value of the selected node from
5. The road now has a banking angle of 5 degrees at this
node. RoadRunner interpolates the banking angle between nodes. Because the entire road
previously had a banking angle of 10 degrees, the banking angle now gradually
increases from 5 degrees at this node to 10 degrees at the road edges.
|Angle||Superelevation angle, in degrees, specified as a real scalar. Angle is clockwise-positive relative to the direction in which the road was created. You can specify the superelevation angle of the entire road or at superelevation nodes along the road.|
|Distance||Position of superelevation node along the road, in meters, specified as a nonnegative real scalar. Distance is relative to the edge of the road that was created first.|
|Slope||Slope of superelevation node tangent, in degrees per meter, specified as a real scalar.|
