USAGE:

Suppose the cross sections are transitioning from a median concrete curb island typical section to an undivided typical with left turning lanes with a raised monolithic concrete island. The Geopak shapes are still configured as a median.

If you create a Geopak shape to the span up to or through the concrete island (red shape), Criteria will not work properly because your are still using the median curbing criteria (mdncc01.cri) and their is no "room" to form a median definition (space or gape between the Geopak shapes (blue shapes) and center line.

At station 35+00, the cross section would look like this without the AutoSwitch variable.

Note that this cross section is not correct.

At station 35+00, the cross section would look like this WITH the AutoSwitch variable.

With the AutoSwitch variable enabled, Roadway Designers can continue to use the median curbing criteria, without manully switching to a new configuration criteria. In addition, NO Additional Geopak Shapes were warranted to process the cross section!
