Creating Roadway Transitions with Templates

and Cross Sections

To create transition regions for a roadway, such as lane widening, use transition

lines. An overview of the steps you need to take to create transitioning are

described in the following list:

Use the Edit Template command to define the transition regions of the

template.

Draw and define the plan view transition lines as alignments if you are using

horizontal transitioning. Or, use the Edit Design Control command to define

these transitions in an editor dialog box. You can also edit the transitioning

for each station with the View/Edit Sections command, and then re-import

the edited values back into the plan view of the alignment with the Import

Plan Lines command.

Draw and define the profiles of the transition lines if you are using vertical

transitioning. Or, use the Edit Design Control command to define these

transitions in an editor dialog box. You can also edit the transitioning for

each station with the View/Edit Sections command, and then re-import the

edited values back into the profile view of the alignment with the Import

Profile command.

Use the Edit Design Control command to attach the offsets from the

horizontal alignments and/or the elevations from the vertical alignments.

Or, you can define this information manually for each station with the

View/Edit Sections command.
