The design criteria file contains standards tables for design speed, superelevation attainment method, and minimum speed, radius, and length of individual alignment and profile sub-elements.
This file can also include criteria to support automatically adding widening to dynamic offset alignments.
If your local agency standards differ from the standards in the supplied design criteria file, you can use the Design Criteria Editor dialog box to customize the file to support your local standards.
