Corridor Models
Preferences (Site Defaults)
Overview
Establish default values for all alignments to use upon initial creation using the dialog below. Local road configurations are specified separately from divided road parameters.
General Settings Tab
This page exposes controls that affect the overall corridor model creation for all alignments, such as section thickness, surface output position (Top or Subgrade) and sampling resolution, in addition to a variety of other settings that affect performance.
A brief description is also provided in a dedicated window located in the lower-right-hand-corner of the dialog. Hover over a setting for information about that setting.
Assembly Schematic
Shows an approximation of the section of the current corridor configuration relative to the top or datum surface.
Curb Control
Sets the reference point for the assembly at the Base Map Control system of choice. Options include the following:
-
Back-of-Curb
-
Top-Face-of-Curb
-
Flow line
-
Edge-of-Pavement
Export Reaction Protocol
Determines what processing will/will not occur after closing the dialog.
-
Generate/Update Rds.
-
Delete Expired Models
Output Surface
Controls which surface of the corridor assembly is output to the drawing editor:
-
Top
-
Datum
Pavement Thickness (Feet)
Provides a control to specify the thickness of the pavement section from top surface to sub-grade. Separate values are stored for corridors based on their classification:
-
Local Roads
-
Divided Roads
Refresh Depth
Determines how much information will be refreshed when the assemblies are regenerated in the drawing editor. Separate values are stored to control either:
-
Rebuild Horizontal Control
-
Rebuild All Corridor Models on Close
Surface Resolution
Allows the user to control the resolution of the output corridor model geometry
