About Rehab Corridor Sections

Use the Rehab Corridor Editor to view and modify rehab corridor sections and to visually inspect how rehab subassemblies are applied at various stations within rehab corridor regions.

When you select a rehab region within a rehab corridor, three default viewports will be displayed, allowing you to view the corridor cross section for the station (cross section view), the vertical profile for the section (profile view), and the location of the corridor cross section along the rehab corridor's alignment (plan view).

Note: The cross section view for the station is displayed in the cross section viewport. Critical points such as lane width, accepted cross slope, offset, milling and/or leveling depth, and any associated design geometry violations are identified. For the plan and profile views, the station tracker identifies the selected station within the rehab corridor region. The selected station is also displayed in the Rehab Corridor Editor ribbon tab. For example, in the image above, all three viewports are displaying views for station 1+80.00'.

Cross Section View

The cross section view shows important information such as width, slope, offset, mill and/or level depth, and any potential violations.

Note: You can use Code Set Style in View/Edit Corridor Section Options to customize the information displayed in the cross section view.

• Width: The width of the lane at the selected station.
• Slope: The accepted cross slope (%) for the selected station.
• Offset: The distance of the outside edge of the lane from the road centerline.
• Mill/Level Depth: The depth of the milling and/or leveling layer at the selected station.
• Violations: Hover your cursor over a violation icon to view violations.
  

  Note: There are four possible violation types:

  • Slope

    If the absolute value of Slope Difference is greater than the absolute value of Slope Tolerance, a violation is displayed.

    If Corrected Cross Slope is not equal to Ideal Cross Slope, a violation is displayed.

  • Relative Gradient

    If the change in corrected slope between two stations relative to the distance in length between the stations is greater than the maximum relative gradient, a violation is displayed.

  • Lane Break

    If the difference in accepted slope between two lanes is greater than the maximum lane break slope, a violation is displayed.

Plan View

Profile View

• Existing Ground (EG)

  Elevation of the existing ground profile for the selected station.

• Design Profile

  Elevation of the design profile for the selected station. The design profile elevation for a rehab corridor region is defined by the vertical baseline that was assigned to the rehab corridor in Corridor Properties during rehab corridor creation.

• Adjusted Elevation:

  For an undivided rehab corridor section, Adjusted Elevation is equal to the crown point elevation for the selected station.

  For a divided rehab corridor section, the Adjusted Elevation is equal to the elevation of the highest elevation crown point of any other crowned subassembly in the assembly. If no crown point exists in the assembly, Adjusted Elevation is set to equal to the Design Profile elevation. If the assembly has a median on the centerline that separates the right and left lanes, the adjusted elevation is equal to the design profile elevation. If there is not a subassembly attached to the baseline, the adjusted elevation is equal to the design profile elevation.
