Use the criteria-based design feature to apply agency-specific standards to a profile.
The criteria-based design feature provides the ability to verify that your profile design meets the minimum standards required by your local agency.
When you use the criteria-based design feature, you can select a design criteria file , from which you can specify the minimum K value table. If the parent alignment also uses design criteria, the design criteria file applied to the alignment is applied for the profile by default. You can specify a separate design criteria file for the profile either during creation or in the profile properties.
When you lay out the profile, the appropriate minimum values specified in the design criteria file are displayed on the command line. You can either accept the default minimum value for a given sub-entity, or specify a new value.
Agency standards, which are typically based on superelevation and design speed requirements, are contained in the customizable design criteria file. When you create the profile, the minimum standards from the design criteria file ensure that the vertical curves comply with the minimum standards required by your local agency.
If the design parameters for a sub-entity violate the minimum values established in the design criteria file, a warning symbol appears both on the sub-entity in the drawing window and next to the violated value in the Profile Entities Vista (Panorama) and Profile Sub-Entity Editor Dialog Box. When you hover the cursor over a warning symbol, a tooltip displays which standard has been violated and how to correct the violation. The display of the warning symbol is controlled by the profile style.
Some profile design criteria are not available in table form in the design criteria file. For these criteria, you can define design checks to validate design standards. A design check must be saved in a design check set to be applied to a profile.
You can generate a report that documents validations or violations in the profile design. The design criteria report identifies whether each sub-entity within a given station range meets the appropriate design criteria and design checks.
