Transitioning a Roadway

To transition a road, you can create plan and profile transition regions

on your finished roadway design. For example, if your highway design

includes a passing lane on a hill, you can add the additional lane to

the plan view of the roadway, define the edge of pavement as a

transition alignment, and then update the cross sections using the

Edit Design Control command.

You can also design vertical alignments in the profile view that

represent vertical transitions, su/jointfilesconvert/425361/bgrade surfaces, or ditch elevations,

and then you can attach these vertical alignments to the cross

sections, updating them with the new elevations.

Key Concepts

■

In order to create transition regions, you need to define transition

control points on the template using the Edit Template command.

■

You can create horizontal and vertical transition alignments to

attach to the cross sections.

■

You can use commands in the Cross Sections

➤

Ditch/Transition

menu to define plan and profile transition alignments. However,

you can also use commands in the Alignments and Profiles menus

to define and edit these transition alignments.

■

If you make changes to the transition alignments using the

View/Edit Sections command or the Edit Design Control command,

then you can use the Cross Sections
