Create the Side Road Corridor

Documentation for Side Road/Driveway Design is composed of four documents, this is Part 4.

Side Roads and drive ways are designed after the Main line corridor has been completed. The horizontal and vertical geometries will match into the Main line.

Note that references to "12345" in file names refer to the project's five digit Project Number.

After the civil cell has been modified, you can create the side road corridor.

  1. Open 54321 Cor - Side Road.dgn. Open the Default model.
  2. Set the active element template to Corridor.
  3. Use Element Selector, with the Individual and New toggles active, and Select the side road geometry to be used to generate the corridor.
    element selector dialog box
  4. Hover over the alignment and the Context Menu popup will appear. Select Create Corridor or go to the Corridor Modeling task menu to select Create Corridor then hit on the alignment.
    context sensitive menu
  5. Reset to use the active profile of the selected alignment or choose another as needed. Set the Design Stage in the box, then type a Name for the corridor into the on-screen tool tip, hit <enter> and left click the mouse to accept.
    create corridor dialog box
  6. After the corridor is created, the Create Template Drop toolbox becomes active. The first prompt is for the template (name). Use the <Alt> <down arrow> to bring up the Pick Template box. Select the Template and hit OK. Left click on the screen to accept the template, then define the start (hit on the centerline limit of the civil cell) and end point. Set the template drop interval = 5 and set the transitions to 0.
  7. After the template is created you can create additional template drops by selecting another template and following the prompts again. Reset to finish placing templates. After each drop is defined, the template is applied to the stations indicated and added to the corridor.

Your corridor has now been created and can be refined using the other corridor creation tools. Many tools work by hitting on the 2D lines that were created. Shut off the display of all the 3D design strings by opening the level display, expanding the tree under the Default-3D model, highlighting the Default-3D model and then right clicking in the levels pane and selecting All Off.

Save Settings and Save the drawing.

To continue this process, follow the Corridor Design documentation beginning at Modify Parametric Constraints.
