Corridor Optimization variables

[abrooker]

Is there any where to edit/set Corridor Optimization variables such as road/swath width, minimum horizontal radius, maximum grade. Thanks for any help on this!

Hi Abrooker,

I'm not certain that you will be able to edit the road width and/or horizontal radius through the Corridor Optimization panel, but you should be able to set Roadside grading limit, cut slope, fill slope, and maximum grade, using the "Construction Rules" and "Profile Constraints" tabs under "Advanced Settings" in the Corridor Optimization panel.

Hope this helps.

Best,

Elliott

Hi Elliott, Under the Corridor Optimization panel / Advanced Settings / Construction Rules I see: - Grading limit (I'm not exactly sure what this means?) - Cut slope - Fill slope but no profile constraints or maximum grade... Thanks for your reply! Adam

Hi Abrooker,

Currently, the minimum horizontal radius is controlled by the design speed input.  Based on the design speed input, Corridor Optimization looks up the AASHTO tables to determine the minimum radius.  The max grade under "Profile Constraints" is for setting the longitudinal profile max grade.

For road width, there are two parts.  One is the roadway width, which is defined in your selected road style on the Corridor Optimization panel.  You can use the Style library to set your roadway width.  The second part, as Elliott suggested, is Grading limit under "Construction Rules".  It defines the max width for a road's side slope (cross section) starting from the edge of a roadway outward. Cut slope and Fill slope are for controlling the side slope.

Regards,

Where do you specifiy which Aashto table to use?

I believe that you set Road Design Standards using the Model Properties dialog box, which is found via:

Click InfraWorks (orange "I") icon > Click Create and Manage > Click Model Properties.

Found these instructions at: http://help.autodesk.com/view/INFMDR/2015/ENU/?guid=GUID-0F194B8A-F337-4463-8115-94E68AAFA5C3

It would be nice to set AASHTO that way for corridor optimization.  Currently, AASHTO is hard coded for corridor optimization.
