CTDOT Highway Manual Figure 11-8B

 

Civil Cells for Driveways have been created to comply with the CT DOT Highway Manual 11-8.0 Driveways.

Both Commercial Driveway and Residential Driveway Civil Cells are similar in Civil Cell Reference requirement and placement. The workflow described will be same for both Civil Cells.

CIVIL CELL REFERENCE REQUIREMENTS

1. Edge of Road (EOR) of main road. EOR should have its own profile.

2. Driveway Centerline drawn perpendicular to Baseline of main road.

3. Driveway Matchline at the back of driveway

NOTE: The number of reference elements can vary for each civil cell.

 

PLACE CIVIL CELL

1. The design file should have Baseline Alignment, Baseline Profile and roadway corridor in order to place civil cell. Profiled Edge of Road will come from template of Corridor.

2. Activate the OpenRoads Modeling workflow from the pick list next to Quick access toolbar in the upper left corner if it is not already active. The ribbon menu will reflect the OpenRoads Modeling tools.

3. From the ribbon, select Geometry Tab.

4. From the Horizontal Group Select Lines > Line Between Points

5. Select Feature Definition > Driveway (Alignment > Center > Driveway) 

6. Using the perpendicular snap draw a Line perpendicular to Baseline of Main Road towards the Proposed Driveway. This is Driveway Centerline. Default name is DCL. User can change it as required.

7. From the Horizontal Group Select Lines > Line Between Points

8. Select Feature Definition > Driveway Match Line (Linear > Roadway Geometry > Driveway Match Line)

9. Draw line crossing the Driveway Center line. This line is the limit of the driveway where it matches the existing driveway or ground. Default name is DrivewayMatch_Line. User can change it as required.

10. Now we have all three references required for placing the Driveway Civil Cell. We can place the civil cell.

11. From the ribbon, select Model Detailing Tab.

12. From Civil Cells Group Select Place Civil Cell.

13. In Civil Cell Name dialog box, click the browse button to open civil cell library.

14. Two options can be chosen from, Commercial Driveway or Residential Driveway as per requirement.

a. For Commercial Driveway, expand the CV_Commercial_Driveway_CivilCells.dgnlib and Select Commercial Driveway (No Provision for Sidewalks) without curb civil cell.

• The dialog displays the planimetric layout of the selected civil cell with black lines
• The dialog also shows the reference lines on which the civil cell is based. These are the red lines and represent the references that must be present within the design file to place the civil cell.

 

b. For Residential Driveway, expand the CV_Residential_Driveway_CivilCells.dgnlib and Select Residential Driveway (No Provision for Sidewalks) without curb civil cell.

 

15. Click OK.

16. Follow the heads-up prompts:

a. Locate Reference Element: EOR (Profiled)(1/3), select the Main Road Edge of Road element.

b. Locate Reference Element: DRV CL (Perpendicular to Baseline) (2/3), select the Driveway Centerline element.

c. Locate Reference Element: DRV ML (3/3), , select the Driveway Matchline element.

d. Select Elements to View Alternatives (Reset to Skip) , there are couple of options according to  the direction of the driveway cell

i) If the direction of driveway cell is correct, then right-click to reset.

ii) If the direction of driveway cell is incorrect, see figure below, hover over the Edge of Road, the arrow should appear over the EOR, left-click on the arrow. This should cause the curb return to flip to the correct side. Note the arrow’s change of direction.

iii)

    

Hover over the EOR until the arrow appears over EOR then left-click on arrow.

The curb return will flip to the correct side.

e. Select Corridors To Be Clipped (Reset To Complete) , right-click to reset.

f. Accept Civil Cell Placement , left-click to accept.

g. The Civil Cell is placed.

ADJUST THE CIVIL CELL PLACEMENT

Series of edits can be done to the Civil Cells which demonstrate the flexibility and the ability to edit their component.

If the capabilities of Civil Cells seem confining, user can use the Drop Civil Cell  tool to drop the placed Civil Cell into the components that make it up.

Add Template Drops at Civil Cell Locations

It is preferred to add template drops over clipping the corridor when blending the civil cell to the corridor.

Note: Issue with Civil Cell Clipping

Driveway Civil Cells can be used to clip the corridor where it is placed. But this method does not work every time. Civil Cell clipping does not clip out 2D graphics of the corridor but only in 3D view. Template edit of the main road corridor is recommended. Dropping elements outside of the curb from the corridor template at driveway limits is recommended for this civil cell.

There is various method to edit the template drop. One method is shown below.

1. From the ribbon, select Corridors Tab.

2. From the Create Group Select Copy Template Drop.

3. Follow the heads-up prompts.

4. At Locate Template Drop, Select the Main road Corridor Template Drop.

5. For Start Station, keypoint snap at start of right-side radius of driveway. For end station, keypoint snap at end of left-side radius of driveway. This will create copy of existing template drop at the driveway portion.

6. This newly copied template drop needs to be edited. From the Edit Group Select Edit Template Drop.

7. For Locate Template Drop, Select the Newly Copied Template Drop.

8. Editing Roadway Designer Template Drop Window appears along with the existing template used at the template window.

9. Delete the end conditions component from the template. For this right-click in the template window and select Delete Components from the drop-down menu.

10. Draw a line across each of the elements you wish to delete.

 

 

11. Click OK to close the Editing Roadway Designer Template Drop dialog.

12. Review the driveway location. Notice the side slopes have been removed along the right side of the main road or across the newly placed driveway civil cell. The designer needs to add and transition the side slope at the curb return.

       

ADJUSTMENT OF REFERENCE ELEMENT

The placement of Civil Cells can be edited by editing the reference elements from which it was placed.

     

Users are advised to draw the Driveway Centerline perpendicular to Baseline of main road. But Driveway Civil Cell can be placed at a situation when there is slight angle between Driveway Centerline and Main Road Baseline.

1. Using the Element Selection tool, select the Driveway Centerline 

2. Move the end point of the Driveway Centerline by using the element handlers, (the circles and arrows on the selected element).

Click on the circle at the end point of the Driveway Centerline element and modify the angle of the intersection.

3. The civil cell will update.

 

Edit Horizontal Geometry

1. Turn off the display of the Referenced 3D model, if it is not already turned off.

One “challenge” in editing Civil Cells is that sometimes it is hard to select what user want to select, especially with full 3D Civil Cells. User may have multiple overlapping 2D features overlapped with multiple overlapping 3D Features in the reference 3D Model. User may have to right-click a couple times to select the intended element.

Depending on user needs, user can turn off the Level of the 3D Model Reference or turn off its Display entirely. User can also turn off levels with graphics user find “unnecessary” right now. Construction Class element display can be turned on and off via View Attributes.

2. Widen the Lane of Driveway Civil Cell.

a. Use the Element Selection tool and Click on the right Edge of Driveway of the Civil Cell.

Tip: It may be easier to select it by hovering over its “gap”. Element at gap is not visible until user hover over it.

The Edges of Pavement are full-length offsets from the centerline. The curb returns create “gaps” where the edges are trimmed back, but trimmed features are still able to be selected in its “gaps”.

b. Once the edge is selected, click on the midpoint Offset text manipulator.

c. Type desired value say 14’ and hit Return. The pavement is widened, and all dependent geometry and modeling is updated.

     

To widen the Left Lane of Driveway Civil Cell, the steps to follow are same as widening right Lane.

3. Change the Curb Return Radius of Civil Cell.

a. Click on the right Edge of Driveway curb return. This might require multiple right-clicks until the Radius value is visible.

b. Click on the Radius text manipulator.

c. Type desired value say 25’ and hit Return. The Curb Return Radius and all dependent geometry and modeling is updated. 

     

4. Change the Width of Driveway Shelf or Ramped Section of Civil Cell.

a. Use the Element Selection tool and Click on the DRV Shelf Line.  

b. Once the line is selected, click on the midpoint Offset text manipulator. 

c. Type desired value say 15’ and hit Return. The ramp section is widened, and all dependent geometry and modeling is updated.

     

Edit Vertical Geometry

As per CTDOT standards, the driveway is provided with 1½” lip at the Edge of Road and Driveway Shelf line is placed 4” vertical offset from the edge of roadway. Driveway match line takes the elevation from the existing terrain.

1. Select the Driveway Centerline (1-CC_Pr DRV CL).

2. Hover over the selected element until the Context Tool Bar pops up.

3. Click open profile model. 

4. On Select or Open View model prompt, select one of the views and left-click on that view window.

ADJUSTMENT OF REFERENCE ELEMENT

The placement of Civil Cells can be edited by editing the reference elements from which it was placed.

     

 

Users are advised to draw the Driveway Centerline perpendicular to Baseline of main road. But Driveway Civil Cell can be placed at a situation when there is slight angle between Driveway Centerline and Main Road Baseline.

1. Using the Element Selection tool, select the Driveway Centerline.  

2. Move the end point of the Driveway Centerline by using the element handlers, (the circles and arrows on the selected element).

Click on the circle at the end point of the Driveway Centerline element and modify the angle of the intersection.

3. The civil cell will update.

 

EDIT HORIZONTAL GEOMETRY

1. Turn off  the display of the Referenced 3D model, if it is not already turned off.

One “challenge” in editing Civil Cells is that sometimes it is hard to select what user want to select, especially with full 3D Civil Cells. User may have multiple overlapping 2D features overlapped with multiple overlapping 3D Features in the reference 3D Model. User may have to right-click a couple times to select the intended element.

Depending on user needs, user can turn off the Level of the 3D Model Reference or turn off its Display entirely. User can also turn off levels with graphics user find “unnecessary” right now. Construction Class element display can be turned on and off via View Attributes.

2. Change the Width of Driveway Shelf or Ramped Section and Sidewalk width of Civil Cell.

a. Make sure Constructions option is turned on in View Attributes window.

 

b. From the ribbon, select Home Tab.

c. From the Primary  Group, Select Level Display.

 

d. Turn on the display for Level “CIVILCELL_Const” if it’s not on already.

 

e. Use the Element Selection tool and Click on the Sidewalk Front Line whose feature name is 2-CC_Const_SW Ft.

f. Once the line is selected, click on the midpoint Offset text manipulator.

g. Type desired value say -4’ and hit Return to coincide with the existing Sidewalk front. The driveway shelf section is widened, and all dependent geometry and modeling is updated.

  

h. Use the Element Selection tool and Click on the Sidewalk Back Line whose feature name is 2-CC_Const_SW Bk.

i. Once the line is selected, click on the midpoint Offset text manipulator.

j. Type desired value say -4’ and hit Return to coincide with the existing Sidewalk back. The sidewalk is widened, and all dependent geometry and modeling is updated.

 

 

3. Widen the Lane of Driveway Civil Cell.

a. Use the Element Selection tool and Click on the right Edge of Driveway of the Civil Cell.

Tip: It may be easier to select it by hovering over its “gap”. Element at gap is not visible until user hover over it.

The Edges of Pavement are full-length offsets from the centerline. The curb returns create “gaps” where the edges are trimmed back, but trimmed features are still able to be selected in its “gaps”.

b. Once the edge is selected, click on the midpoint Offset text manipulator.

 

 

c. Type desired value say 14’ and hit Return. The pavement is widened, and all dependent geometry and modeling is updated.

d. Sidewalk Matchline also moves as driveway width is changed. Designer needs to adjust the limits of Template drop.

To widen the Left Lane of Driveway Civil Cell, the steps to follow are same as widening right Lane.

 

4. Change the Curb Return Radius of Civil Cell.

a. Click on the right Edge of Driveway curb return. This might require multiple right-clicks until the Radius value is visible.

b. Click on the Radius text manipulator.

c. Type desired value say 25’ and hit Return. The Curb Return Radius and all dependent geometry and modeling is updated.

ADJUSTMENT OF REFERENCE ELEMENT

For this section please refer to previous civil cell as the process is identical.

Designers may need to adjust the curb transitions manually after the adjustment of the Reference Element.

 

EDIT HORIZONTAL GEOMETRY

1. Turn off the display of the Referenced 3D model, if it is not already turned off.

One “challenge” in editing Civil Cells is that sometimes it is hard to select what user want to select, especially with full 3D Civil Cells. User may have multiple overlapping 2D features overlapped with multiple overlapping 3D Features in the reference 3D Model. User may have to right-click a couple times to select the intended element.

• Depending on user needs, user can turn off the Level of the 3D Model Reference or turn off its Display entirely. User can also turn off levels with graphics user find “unnecessary” right now. Construction Class element display can be turned on and off via View Attributes.
