Urban Road Design

Instructions for use

The Urban Road Design function can quickly build urban road and intersection models based on the Source Data set (with Network Dataset as the best) and Parameters information.

Function entrance

  • 3D Geode sign Tab-> Rule-based Modeling Group - Procedural Modeling drop-down menu-> City Road Design button

Operation steps

  1. Open the Target Datasource containing the Source Dataset (preferably Network Dataset) in Workspace Manager to create or open an existing scene. Note: The Source Data set must contain the Road Grade (or Road Type) field, the Road Name (or other road marking information) field, and the Type is text.
  2. Click Road in the Procedural Modeling drop-down menu in the Rule-based Modeling group on the 3D Geode sign tab Design button.
  3. In the pop-up Project Path Setup "dialog box, Custom Settings Urban Road Design the project storage path, which is C: \ SUModelingWorkDir by default. When the setup is complete, click OK. The Urban Road Design tab opens.
  4. Set Road Rules: Click Project under the City Road Design tab Management group road style button, set the Road Design rule in the pop-up road style panel. If the default rule applies to the existing data, you can skip directly to step 5.
      All road styles are listed in the
    • panel, and the corresponding field values of road styles in the Source Data set should be included.
    • The panel toolbar provides buttons for adding, importing, exporting, and deleting.
      • Add: Adds a road style with the specified name.
      • Import: Select Specify Road Rule File (*. XML) into the program.
      • Export: Export all road styles contained in the panel to the specified path in the form of Road Rules files (*.xml).
      • Delete: Delete the selected road style.
    • After double-clicking a road style, a dialog box will pop up, in which all road elements included in the road style will be listed, including lanes, bus lanes, Non-Motor Vehicle lanes, sidewalks, shoulders, and median strips.
      • The dialog toolbar provides the Rollback, Forward, and Delete buttons. The Rollback button is used to undo the previous step. The forward button is used to resume the previous single-step operation. The Delete button is used to delete the road element selected on the preview page.
        • A road element button is provided at the bottom of the
      • dialog box. Elements can be added by dragging them directly to the preview page of the dialog box. Select an element in the preview page and drag it directly to change the layout of the element.
        • Double-click a specific element
      • on the preview page to adjust the element attribute values in the Lane Attributes dialog box that pops up, including Road Type, Road Width, Orientation, Stop Line, Guiding Arrow, etc.
      • Road Type setting: Select Road Type from the drop-down menu on the right.
      • Road Width: Set the Road Width in meters by typing the value directly.
      • Orientation: Select the road orientation, including front and back. The front represents the direction facing the screen inward, and the back represents the direction facing the screen outward.
      • Stop line: set whether there is a stop line and the thickness of the stop line, in meters.
      • Guiding Arrow: Sets whether there is a Guiding Arrow and its Initial Distance and Step Size. Initial Distance lets you set the distance, in meters, from the stop line for the Guiding Arrow. Step can be used to set the separation distance between Guiding Arrows in meters.
  5. Import road network data: Click Project under the Urban Road Design tab Management group Import Road Network button, and the Import road network data "dialog box pops up. The specific operations are as follows:
    • Datasource: Click the Drop-down Button on the right to select the Datasource where the source Network Dataset is located.
    • Dataset: Click the Drop-down Button on the right to select the target Network Dataset.
    • Road style: Click the Drop-down Button on the right to select the field representing the road style.
    • Road Name: Click the Drop-down Button on the right to select the field representing Road Name.
      • When the
    • settings are complete, click OK.
  6. Once set up, the Source Data set is loaded into the scene and the city road is constructed based on the Road Rules.
  7. The road details can be adjusted as required. After selecting a specific road, select the " Road Editing " panel in the Context Menu to list the road elements contained in the road.
    • Toolbar: The toolbar provides the Add, Move Up, Move Down, and Delete buttons to add, sort, and delete road elements.
    • General Properties: Set the Road Type and Road Width. Set the Road Type through the drop-down menu. Set the Road Width by typing directly. The unit is meters.
    • Lane Attributes: Set the lane orientation. Set the road orientation to front or rear by checking the radio box.
    • Stop line: set the stop line thickness in meter. After checking the stop line check box, type the specific value directly in the thickness dialog box.
    • Guiding Arrow: Set the Initial Distance and Step of Guiding Arrow. When the Guiding Arrow check box is checked, type a numeric value directly in the Initial Distance dialog box to set the distance of the Guiding Arrow from the stop line; type a numeric value directly in the Step dialog box to set the separation distance between the Guiding Arrows.
  8. Import Project File: Click the Project Management group Import under the Urban Road Design tab Project File button to open an existing Urban Road Design Config File (*.srd) in the current scene.
  9. Export Project File: Click the Project Management group Export under the Urban Road Design tab The Project File button can export the design results in the current scene as Urban Road DesignConfig File (*.srd) and store them in the specified path with the specified file name. The Urban Road Design Config File records the design content in the current scene.
  10. Generate Tiles: Click the Project Management group Generate under the Urban Road Design tab Tiles button will generate the design result as S3MTile Data under Project Path.
  11. Auxiliary Functions：
    • Locate: Click Auxiliary under the Urban Road Design tab The Functions group navigation button will display the current design results panorama.
    • To exit: Click Auxiliary under the Urban Road Design tab The Functions group exit button will exit the Urban Road Design process.
