Creating a Carriageway

This process is discussed as part of the Quick Setup here.

Carriageway Settings

The global settings and edits available for carriageways are explained here and on a User by User basis here.

Carriageway Shape Configuration

Unlike some of the other shape, space and area related entities, carriageways have certain specific configuration processes.

1. Under the Config tab, select the carriageway whose shape you wish to adjust.
2. Select Edit.
3. The carriageway can be moved in its entirety through Ctrl+Click+Drag when the🕂move icon appears. 
4. But for more complex adjustments, examine the multiple circular icons of differing colours now visible on the carriageway. We call these points.
5. The different functions of the points can be discerned by their colour:
   1. Section Points: pink.
   2. Lane Points: orange.
   3. Nodal Points: green and blue.
   4. Virtual Area Points: red.
6. To isolate specific points, the Point Filter box has a dropdown of options:
   1. Show All: all points visible and available for configuration.
   2. Sections: section points visible and available for configuration.
   3. Lanes: lane points visible and available for configuration. 
   4. Nodes: nodal points visible and available for configuration.
   5. Virtual Area: VA points are always visible and available for configuration, despite any of the above being selected. However, this option leaves solely VA points visible.

7. All points can be moved through Click+Drag. However, certain movements are constrained:
   1. Section points: can only move up and down the carriageway.
   2. Lane points: can only move from side to side of a carriageway, along a node.
   3. Node points: can only move as far as the opposing side of the carriageway. The corresponding VA point moves with a node point, but the opposing node point remains in position - to move one node point just stretches a node.
      1. To move the entire node (both nodal points), select Ctrl+Shift+Click+Drag over the blue node point.
   4. VA points: cannot move inside a carriageway, so a Virtual (detection) Area is always maintained inside the carriageway.
