Middle Curve Elevation Adjust sets a relative change in elevation from the outer edge of the roundabout to the middle point of the inner curve of the slip lane.
Select Entry has an additional elevation adjustment to enable the Entry Elevation Adjust and Entry Elevation Adjust Offset fields.
Entry Elevation Adjust sets a relative change in elevation from the outer edge of the roundabout to the start of the curve of the slip lane.
Entry Elevation Adjust Offset sets how far from the Middle Curve Adjustment location towards the entry that the Exit Elevation Adjust value is applied.
Select Exit has an additional elevation adjustment to enable the Exit Elevation Adjust and Exit Elevation Adjust Offset fields.
Exit Elevation Adjust sets a relative change in elevation from the outer edge of the roundabout to the end of the curve of the slip lane.
Exit Elevation Adjust Offset sets how far from the Middle Curve Adjustment location towards the exit that the Entry Elevation Adjust value is applied.
Entry Transition Distance is measured as the transition from the incoming crossfall defined at the entry to the crossfall that applies along the deceleration section.
Entry Region Crossfall is the section of the slip lane after the Entry Transition Distance.
Entry Curve Transition Distance is measured as the distance before the curve in the deceleration section of the road that transitions between the Entry Curve Crossfall value and the Entry Region Crossfall value.
Entry Curve Crossfall sets the crossfall value for the entry curve.
Middle Cure Crossfall sets the crossfall value for the middle of the curve.
Exit Curve Transition Distance is measured as the distance before the curve in the acceleration section of the road that transitions between the Exit Curve Crossfall value and the Exit Region Crossfall value.
Exit Region Crossfall is the section of the slip lane before the Exit Transition Distance.
Exit Transition Distance is measured as the transition from the outgoing crossfall defined at the exit to the crossfall that applies along the acceleration section.
