Urban Road Design

Instructions

The Urban Road Design function can quickly construct urban road and intersection models based on the original dataset (a network dataset is recommended) and relevant parameter information.

This function currently only supports use on the Windows operating system.

Function Entry

  • 3D Geographic Design Tab -> Regularized Modeling Group -> Procedural Modeling Drop-down Menu -> Urban Road Design Button

Operation Steps

  1. In the Workspace Manager, open the target datasource containing the original dataset (a network dataset is recommended), and create a new scene or open an existing one. Note: The original dataset must contain a road level (or road type) field and a road name (or other road identification information) field, with the field type being text.
  2. Click the Urban Road Design button within the Procedural Modeling drop-down menu of the Regularized Modeling group under the 3D Geographic Design tab.
  3. In the popped-up "Project Path Setting" dialog box, customize the storage path for the urban road design project. The default is C:\SUModelingWorkDir. After setting, click OK to open the Urban Road Design tab.
  4. Set Road Rules: Click the Road Style button in the Project Management group under the Urban Road Design tab. Set the road design rules in the popped-up Road Style panel. If the default rules are suitable for the existing data, you can skip directly to step 5.
    • The panel lists all road styles, which need to include the corresponding field values for road styles in the original dataset.
    • The panel toolbar provides Add, Import, Export, and Delete buttons.
      • Add: Adds a road style with a specified name.
      • Rename: Renames the specified road style.
      • Import: Selects a specified road rule file (*.xml) to import into the program.
      • Export: Exports all road styles contained in the panel as a road rule file (*.xml) to a specified path.
      • Delete: Deletes the selected road style.
    • Double-clicking a road style will pop up a dialog box listing all road elements included in that style, including lanes, bus lanes, non-motorized vehicle lanes, sidewalks, shoulders, and central dividers.
      • The dialog toolbar provides Rollback, Forward, and Delete buttons. The Rollback button is used to undo the previous single-step operation. The Forward button is used to restore the previous single-step operation. The Delete button is used to delete the road element selected in the preview page.
      • The bottom of the dialog provides road element buttons. Dragging an element directly to the preview page of the dialog can add the element. Selecting an element in the preview page and dragging it can change the element's arrangement.
      • Double-clicking a specific element in the preview page opens the Lane Properties dialog box, where you can adjust element attribute values, including road type, road width, orientation, stop line, guide arrows, etc.
      • Road Type Setting: Select the road type from the drop-down menu on the right.
      • Road Width: Set the road width by directly entering a numerical value, in meters.
      • Orientation: Select the road orientation, including Front and Back. Front represents the direction facing inward toward the screen, and Back represents the direction facing outward away from the screen.
      • Stop Line: Set whether there is a stop line and the thickness of the stop line, in meters.
      • Guide Arrows: Set whether there are guide arrows and their initial distance and step length. The initial distance can be used to set the distance from the stop line for the guide arrow, in meters. The step length can be used to set the interval distance between guide arrows, in meters.
  5. Import Road Network Data: Click the Import Road Network button in the Project Management group under the Urban Road Design tab. The "Import Road Network Data" dialog box will pop 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 the road name.
    • After setting, click OK.
  6. After setup is complete, the scene will load the original dataset and construct urban roads based on the road rules.
  7. Road details can be adjusted as needed. Select a specific road and choose Edit from the right-click menu. The Road Editing panel will list the road elements contained in that road.
    • Toolbar: The toolbar provides Add, Move Up, Move Down, and Delete buttons to add, sort, and delete road elements.
    • Basic Properties: Set the road type and road width. Set the road type via the drop-down menu and set the road width by directly typing, in meters.
    • Lane Properties: Set the lane orientation. Set the road orientation to Front or Back by checking the radio button.
    • Stop Line: Set the stop line thickness, in meters. After checking the Stop Line checkbox, directly type the specific value in the Thickness dialog.
    • Guide Arrows: Set the initial distance and step length for the guide arrows. After checking the Guide Arrows checkbox, directly type the value in the Initial Distance dialog to set the distance from the stop line for the guide arrow; directly type the value in the Step Length dialog to set the interval distance between guide arrows.
  8. Import Project File: Click the Import Project File button in the Project Management group under the Urban Road Design tab to open an existing urban road design configuration file (*.srd) in the current scene.
  9. Export Project File: Click the Export Project File button in the Project Management group under the Urban Road Design tab to export the current design results in the scene as an urban road design configuration file (*.srd) and store it with a specified filename at a specified path. The urban road design configuration file will record the design content in the current scene.
  10. Save as Dataset: Click the Save as Dataset button in the Project Management group under the Urban Road Design tab to save the design results to a specified datasource.
    • Datasource: Select a datasource in the workspace via the drop-down menu to save the result dataset, or create a new datasource at a specified path via the New button to save the result dataset.
    • Save Model: Set whether to save the design results as corresponding model datasets, such as road, divider, motorway lane, non-motorized vehicle lane, crosswalk, etc. Checked by default.
    • Save Vector: Set whether to save the design results as corresponding vector datasets, such as saving road centerlines as 3D line datasets, and dividers, crosswalks, etc. as 3D region datasets. Checked by default.
  11. Generate Tiles: Click the Generate Tiles button in the Project Management group under the Urban Road Design tab to generate S3M tile data from the design results under the project path.
  12. Auxiliary Functions:
    • Locate Road Network Data: Click the Locate Road Network Data button in the Auxiliary Functions group under the Urban Road Design tab to display the panorama of the current design results.
    • Exit: Click the Exit button in the Auxiliary Functions group under the Urban Road Design tab to exit the Urban Road Design process.
