■ At station 0+304.54, the left lane (dark red) starts to transition from the normal -2% slope. NOTE For the remainder of the curve, the dark red line is not visible because it is obstructed by the light red line. ■ At station 0+316.71, the left lane and shoulder are at 0% slope. ■ At station 0+328.88, the right lane (dark blue) starts to transition from the normal -2% slope. ■ At station 0+344.71, all elements are fully superelevated: the left lane and shoulder are at 5%, the right lane is at -4.60%, and the right shoulder is at -5%. Starting at station 0+512.66, the lanes begin to transition out of the fully superelevated state. 3 Pan to the area of the superelevation view that has Curve.4 labels on the horizontal axes. Notice that there is a curve where each line transitions in or out of a superelevated state. Curves are present on this superelevation curve, but not the others, because you selected the curve smoothing option during Exercise 2: Calculating Superelevation for an Individual Curve (page 264). Later in this exercise, you will learn how to apply curve smoothing to an existing superelevation curve. To continue this tutorial, go to Exercise 4: Adding and Modifying Superelevation Stations (page 269). Exercise 4: Adding and Modifying Superelevation Stations In this exercise, you will resolve overlap between two superelevated curves by adding and removing critical stations, and then editing existing superelevation data. For more information, see Editing Superelevation Data in the Tabular Editor. This exercise continues from Exercise 3: Creating a Superelevation View (page 267).
