Summary
The median curbing criteria provides for medians with curbing on both sides with a raised concrete or grass area in between. The designer has the ability to specify the type of curb and /or gutter to be used on either side of the median. Curbing can be oriented on the edge of the template or if shoulders are used, on the shoulder point. Note: The median curbing criteria can be used to create a concrete monolithic island by defining both curbs types as 9 (Median Curb) and "MCC01 COVER" as 1.
User Defined Variables:
"MCC01 LEFT CURB TYPE"
"MCC01 RIGHT CURB TYPE"
The designer should define the value of these variables according to the desired curbing type for the left side and the desired curb type on the right side of the median. For curbing type numbers, see Table 4-17.
The default definition for both is 1.
"MCC01 LEFT CURB ORIGIN"
"MCC01 RIGHT CURB ORIGIN"
These variables are obsolete and not used in this criteria library version. Their presence in existing input files will be ignored.
"MCC01 COVER"
Define as 1 when concrete cover on median area is desired. Default definition = 0.
"MCC01 BASE DEPTH"
Define as the depth of the base course under the curb. This definition is used
on both sides of the median. Define as inches or meters. Default definition
= 3 feet.
"MCC01 CONCRETE ISLAND AUTOSWITCH" New!
When defined as 1, criteria will automatically switch from a divided typical
section to a undivided typical configuration. This variable is applicable to
a divided facility with the grade point at the centerline, common on projects
with grass or concrete median islands. This variable must be accompanied by
the "Concrete Island" variable described below. If the "Concrete
Island" element is found and this variable is defiined as 1, then the median
curbing criteria is negated. The finished pavement is drawn to the grade point
and the subgrade is drawn at full depth to the centerline. A Concrete Island
(Surface Mounted), 2006 STD. 852.01, is then drawn at the intersection location
corresponding to the plan view on the cross section. If the "Concrete Island"
element is not found, then criteria will revert back automatically to the default
median curbing criteria.Note that the Geopak shapes can remain in a divided
configuration. This variable assumes that the concrete island is located between
the two Geopak shapes (in the median). Default definition = 0.
Example:
DEFINE "MCC01 CONCRETE ISLAND AUTOSWITCH" 1

a sample file and usage of this variable.
"CONCRETE ISLAND" New!
This variable is defined via a DEFINE_DGN statement, and specifies
the level name of concrete island elements in the a plan view graphic design
file. Note that the DEFINE_DGN "CONCRETE ISLAND" line statement is
used in conjunction with the "MCC01 CONCRETE ISLAND AUTOSWITCH" variable.
Example:
DEFINE_DGN "CONCRETE ISLAND"\
DGN = R2006_RDY_DSN.DGN\
LVNAME = PROP CONC 5IN
MONOLITHIC KEYED IN ISLAND
The following variables are local versions of global variables. They define standard level/symbology values that should usually remain static. These variables are listed here for documentation and thereby make them available for pre-definition over-rides.

Technical Notes
The median curbing criteria must be able to set the slope on some types of gutters according to the pavement slope at the edge of the gutter using previously marked points. It is also designed to work with and/or without shoulders. Therefore, it must have a way to tell whether to set the gutter slope by using template points or shoulder points.
This is accomplished by using the internal variable _d_PreviousCriteriaType . The value of this variable specifies whether the mdncc was included after tmplt or shld criteria. After this determination has been made, mdncc can set the internal variable _d_MCC_SlopeAtOrigin to the value of either _d_TM_PavementSlope or _d_SH_ShoulderSlope .
