This tutorial demonstrates how to create and modify alignments.
You begin creating an alignment by marking the location of straights and intersection points for a road centerline alignment. During the creation process, curves between the straights can be created automatically, or added later. To accommodate high-speed travel, transitions and superelevation can be added to the curves. You can enter numeric parameter values for lines, curves, and transitions in the Alignment Elements table.
If your alignment design must meet minimum standards, you can apply design criteria to an alignment either before or after it is created. This tutorial demonstrates basic alignment creation tasks. For information on applying design criteria to an alignment, see the Designing an Alignment Using Local Standards tutorial.
